Proper sharpening of tape saw in winter. Divorce of the teeth of the saw

The angle of sharpening of the strip drain in the winter. DIY DIY DIY DIY DIY and Sharpening

To reduce the friction of the saw on the walls of the cut and exclude clamps in the propyla, it is necessary that the width of the cut is slightly larger than the thickness of the saw blade. To ensure this requirement, the teeth of saws are diluted or flattened. The divorce of the teeth is that the teeth drank alternately bend on both sides: odd in one, and even in the other. Distinguish between two methods of divorce of teeth: direct divorce and turn with a turn.

SV-80 MN 39000 /pcs

The SV-80MN divorce device is designed for simultaneous bilateral wiring of the teeth of tape saws up to 80 mm wide, used on horizontal and vertical tape sawmills and tape-dentic machines.

It is carried out according to the repeated scheme: to the tooth to the left, directly (without wiring) to the right to the right. Teeth diluted to the left and right serve for sawing. and a straight tooth without wiring serves to remove sawdust.

In this type of device, simultaneous wiring of teeth in both directions is provided (left and right). In this case, the center tooth, as expected, remains direct and not divorced.

The divorce is about 0.5 saw thickness with a deviation from size by 0.02. 0.03 mm. over, for soft wood, the size of the divorce is greater than for a solid. It is recommended to check the size of the wiring of new saws, as well as sharpened, After sharpening, the wiring is reduced.

Distinctive features: wiring of teeth simultaneously in both directions; When rotating the handle, pushers of the supply of saw and divorce of teeth are driven into motion; Two types of teeth divorce: left-right; left-right. The possibility of wiring tape saws of any brands of simplicity and reliability of the structure; High accuracy of stripping ribbon; Low cost and fast payback.

Divorce ribbon machine “Taiga

The necessary equipment for maintaining tape saws is a machine for wiring tape saws.

The machine is mechanical, easy to maintain and reliable in operation.

Taiga’s divorce machine, made by our enterprise, has a number of design features that distinguish it from other machines:

Light adjustment of the installation of tape saws in height processing. Fixation of the switch indicator by means of reliable fastening. The possibility of free installation of adjustable supports to support the saw in length. A plate of high.alloy steel (65 g) on ​​the supporting matrix is ​​installed. it does not allow the hot teeth of the tape saw to wash the metal in an important site. The presence of a string pitch fixer. Control of the accuracy of a divorce of teeth immediately after pressing the machine lever.

It is important to remember that for a perfectly prepared for high.quality sawing, a saw prepared according to the following technology is a saw: Dear divorce. Sharpening of teeth- dentition divorce (refinement).

There are such concepts as winter and summer divorce of tape saws. For frozen and solid wood, the size of the teeth divorce is increased, for soft and fibrous wood, the divorce is reduced.

Sharpening of tape saw

First of all, starting to sharpen tape saws, you should know.

The fact that the correctness of the implementation of this process depends on how high.quality your lumber will be. boards, timber, rails, etc.D.

As a result, the sharpening of strip saws, the process is responsible, but not very complicated.

Observing the recommendations below, you will quickly learn this simple, but very useful process in logging. First of all, it is necessary to inspect the tape for the presence of visible cracks, broken teeth. To do this, take the tape into your hands with teeth from yourself and moving your hands, slightly wringing the tape, start viewing.

If defects are detected, the tape must be sent for repairs, or just throw it away. Secondly, the tape must be cleaned of dirt and wood resin sticking to it.

And only after all these procedures the tape is ready for sharpening. First of all, carefully take the tape to avoid injuries. Because the teeth have a sharpness capable of damaging your hands. And insert it on the machine for sharpening. The tape must be installed on all holders on the machine and fixed with a special clamp.

The tape must be installed on all holders on the machine and fixed with a special clamp. In the groove between the teeth we lower the pusher bar, using this bar the feed is adjusted.

At this moment, a sharpener is lowered on top of the tape, it is fixed with a rod that regulates the depth of sharpening. Before starting the launch of the sharpening machine, put the angle of sharpening.

Typically, for summer forests, this angle is 55-60 degrees, and for the winter 70-80. The angle is set by turning the bed on which the stone is fixed, according to the divisions, on the body of the machine.

Make Any Saw a Track Saw #shorts

Pay attention, the sharpening stone has a chamfer at an angle of 45 degrees. During preparation for the sharpening process, you must correct the stone if the chamfer does not correspond to the above corner. Note that the edit is made by a diamond tool or a simple large stone.

Immediately note that the editing with a simple stone is more difficult and requires some skills. Also does not comply with safety regulations. You have prepared a machine and a saw to start sharpening, now let’s proceed to the very process of sharpening the strip saw.

First of all, turn on the feed at the lowest speed. To do this, there are a toggle switch to turn on the engine and the supply speed regulator. It reduces or increases engine speed. Using a screw on the supply rod, take the saw tooth forward or backward. And we follow the stone with the flat side (without a chamfer) began to touch the direct side of the tooth.

Then we turn on the second toggle switch, which sets the engine with a stone. Little by little without sudden movements, you begin to lower the stone. With the help of a screw rod that fixes it, until the stone passes the from one tooth to another.

In no case should the tape be blocked, so try not to lower the stone much.Also, pushing the stem of feeding back or forward, otherwise the stone you just “eat” the tooth should pass smoothly according to the factory profile of the tooth.

Manipulating the feed screws and the rod of lowering the stone must achieve the complete absence of burrs on the tip of the teeth.

The finished work of the machine can be considered after passing the strip saw of at least two circles. Winter sharpening is practically no different from summer with the only difference.

The angle of inclination of teeth more straight reaches 90 degrees, depending on the freezing of wood.

The stronger the wood freezes, the greater the angle of sharpening. But keep in mind that in the summer the load on the saw is enhanced with such an angle and it is possible to quickly get out of the system.

Machines that divorce two teeth are immediately made of the following types: along with a sharpening machine; separately, only a divorce machine operating from the engine; Separately, only a divorce machine with a manual feed in the form of a wheel (photo 1) or lever.

The machine with manual feed in the form of a wheel machine for this option is most advertised by sellers, because they seem to facilitate the work of the sharpener, conducting the divorce of two teeth immediately on both sides of the strip saw. This is a very good advertising “noodles” for the ears of those who have never made tape saws on their own.

Those who at least once prepared a saw for work know very well that each tooth on the saw is divorced individually. The tooth is always diverted with a pusher to a value, greater than the necessary divorce.

When the pusher is withdrawn back, the tooth always shifts to some value back.

over, even for one saw, it can fluctuate backing back of each specific tooth within 5. 25 indicator units. Therefore, the sharpener almost always has to make two or three presses, often to different values ​​of the indicator each (that is, with different effort), to obtain the required divorce value.

There are also teeth that spring worse than others and already at one or two presses before the indicator of the indicator, as on well-springing teeth, remain on values ​​that are large than the necessary divorce, and they have to be specially bend back.Now you should understand that it is just impossible to make two teeth well with one pressing.

There are also teeth that spring worse than others and already at one or two presses before the indicator of the indicator, as on well-springing teeth, remain on values ​​that are large than the necessary divorce, and they have to be specially bend back.Now you should understand that it is just impossible to make two teeth well with one pressing. But the machines are well sold, and some are even satisfied with the result.

Drawing a saw on such a machine, you always need to know: you will never get a guaranteed good divorce of a strip saw.

Divorce will always be unpredictable. With small feeds of the carriage, a accidental batch of a drank with more or less equally spring.loading teeth, a new clean mechanism sometimes manages to saw normally. But problems necessarily arise later.

But they begin to look for the reason for these problems anywhere, but not in the divorce, believing that he is very good. For almost all such divorce manufacturers, even indicators do not put. Explaining this by the fact that you install everything once, and then only breed: the hammers always beat the same and what to check here.

proper, sharpening, tape, winter, divorce, teeth

And you check and see for yourself what a large scatter in the values ​​of the divorce actually.In addition, the accuracy of the resulting divorce in these machines is strongly affected by the same reasons as in the classic ones: the getting of dirt into the mechanism, the risks on the pusher and support plates. The height of the diluted part of the tooth is especially affected.

DIY DIY DIY DIY DIY and Sharpening

Despite numerous attempts to use the saws of other manufacturers, Wood-Mizer could not find a saw that could provide a high-quality cut.

Then it was decided to invest in the development and creation of an innovative product. a band sawdown designed specifically for wood.

It was experimentally discovered that the best alloy is not cheap steel used by other saw manufacturers, but a more expensive alloy from which the famous Wood-Mizer saws of the Doublehard series are now being produced. Also, in the course of research, an optimal tooth profile of 10/30 was developed, which today is the standard in the woodworking industry. Despite the external simplicity, in fact, the Wood-Mizer strip saw is an intellectually capacious product that is tested on millions of sawed cubic meters of wood.

The geometric parameters of the saw are strictly balanced and optimally correspond to the type of sawing wood, engine power and a number of other factors. The Wood-Mizer engineer team is constantly working on the development and improvement of this product.

If earlier, Wood is one tooth profile, now there are four options. Previously, saws of 32 mm and 38 mm wide were made. now saws of 35 mm wide, 45 mm and 50 mm were added to them. That is why the Wood-Mizer saw is copied-after all, they always fake only the best. Today, the Wood-Mizer strip saw is a product that is used in 220 countries by more than 50.000 tape saws.

Today, the Wood-Mizer strip saw is a product that is used in 220 countries by more than 50.000 tape saws.

And everywhere in the world this saw stably and with high quality cuts wood, and its service life provides users with minimum tool costs in calculation for the volume of sawn products.

Material for the manufacture of tape saws

The strip saw for wood is made of instrumental steel with a hardness of 45 HRC, and for metal it is the basis of steel B2F, 9XF, C75, UDDEHOLM UHB 15, and others, for carbon steels, the cutting tool is the tool steel, while hardening of teeth is carried out for which are used high frequency currents.

I would like to note that for cutting metal you can also use a bimetallic saw, which after hardening has a hardness of 65-69 HRC.

Having sorted out a little with the materials from which the strip saws are made, we smoothly move on to the teeth of the cutting tool and their sharpening.

Sharpet teeth and angles

The strip saws have various geometry of the teeth due to various types and properties of the processed material.

If we consider the wood, then the teeth are divided into:

As for the sharpening angles, here the manufacturer determines this parameter. It is mainly accepted that the harder the material, respectively, the less the front angle.

For ribbon saws for metal, teeth usually have a shape. standard or with a positive front angle. I will explain this moment a little: the standard shape of the teeth is used in order to cut thin.walled material, and the form with a positive front angle, as it is already easy to guess, for cutting thick.walled material.

I propose to look at a small picture that can explain what profiles in the tooth can be and where they, these very profiles are applicable.

In addition, a step of teeth is important. So, for example, for thin.walled material, you should use a tool with a small number of teeth, and for thick.walled, on the contrary, with a large number of teeth per inch.

Now let’s take a look at the picture, in which we will clearly see how the saws with a variable pitch of teeth from saws with a constant pitch of teeth are distinguished.

Often, the saws are taken precisely with a variable step in order to eliminate the resonance effect.

Next, I propose to find out what types of string saws are there.

Sharpening of tape saw on wood video.

In previous publications, we started a conversation about the specifics of the acquisition and subsequent operation of sawmills, ribbon-leading machines for the production of chanters and ribbon-saw machines for furniture enterprises. We dwelled in detail on the consideration of the classic method in which the teeth are sharpened by a sharpening circle. And reflected two factors that affect the quality of sharpening. technical and instrumental. The third factor, the last in the list, but the main thing in fact, is the human factor.

When choosing a person to work by a sharpener, pay first of all attention to his character. Hot, explosive, trying to make everything quickly a person will never become a good sharpener. Here you need a calm, attentive, reckless, responsible person who is able to do a long time to monotonous work. But even this is not enough. Good sharpeners are obtained only from those who can literally feel the saw and only by rumor to configure a hiding machine. No wonder the people say that a good sharpener should be born. And indeed it is. Since it is simply impossible to mechanically sharpen the strip saw in this way for the above and below reasons is almost impossible.

Now we will show what exactly it is necessary to do the sharpener in the process of work.

The sharpening process must be started with the inspection of the machine:

  • It is necessary to check the alignment of the sharpening circle and the plane of the strip saw so that they are strictly perpendicular. Otherwise, the tooth will sharpen the bevel to the side.
  • Put a hubby circle to the desired angle in relation to the plane of the saw, that is, set the front angle of the tooth along the limits of your machine. Since these limbers never correspond to reality, setting the saw, check the corporator received the real angle. If he does not suit you, slightly change the installation of the corner to the required side. Pot the saw again and check the resulting angle. And so until you get the necessary angle. It is advisable to do this with great hardness, so that during the installation the circle does not lose its shape. Otherwise you will have to rule it and thereby knock down preliminary installations. After you got the required angle on the saw, take a note on the machine. It will then come in handy with new reinstates to other angles.
  • All moving parts should have minimal backlash, and it is better that they are not completely, otherwise they will be accelerated by the profile of the teeth and a hiding circle.
  • The cooling fluid should be supplied in such a way that the entire hidden tooth is washed, otherwise the part of the tooth will necessarily be used where the fluid will not get.
  • The hollow circle must be installed the desired size and sufficient hardness so that its profile does not change at least one full pass, otherwise the saw will have a different tooth profile along the entire length.
  • During sharpening, it is impossible to change the adjustment of the sharpening circle until the full passage is protected, otherwise a different profile will turn out to be a different profile and the circle will either burn the profile or pass without touching it without touching it.

Settings of the sharpening circle are made by two screws:

After preparing the sharpening circle, install the strip saw and, scrolling the circle with your hand or at a minimum feed, check how accurately it goes through the profile. If necessary, discover the circle again.

After the end of the work, it is necessary to clean the mud, metal sawdust and rust mechanism of the saw clip, a pan for coolant; check the fluid level and, if necessary, add it; Wipe the whole machine.

The main reason for the incorrect sharpening of the strip saw is the loss of the sharpening circle of its shape.

How to SHARPEN a SAW. “Take Time to SHARPEN the SAW”! For your LIFE and your PRUNING.

If the technical problem can be solved using the high-quality manufacture of the machine itself (for example, the Vollmer company produces very good machines), if the instrumental problem can somehow be solved by the proper selection of a sharpening circle, then the problem of forming the profile of the sharpening circle cannot be well solved even theoretically.

Only very experienced sharpeners or people with an inner instinct can come close to understanding and the most accurate execution of the profiling of the end of the sharpening circle. I will explain this by example. Spend a horizontal fishing line for a trimmer on a sheet of paper. Now, from this line to the right side, draw two vertical lines to the eye: one at an angle of 10 °, and the second after 3 mm at an angle of 40 °. Now connect the left fishing line for a trimmer with a horizontal straight line through a radius of 1.5 mm, and the right fishing line for a trimmer is through a radius of 1-2 mm. Do this several times and check with the help of the transporter that you did. For clarity, you can combine these sheets. Keep in mind that the discrepancy between the data is only 0.5 ° already leads to inaccurate protrusion of the profile. And inaccurate connection of the left straight line also leads to a change in the pile of the saw. Now imagine that the sharpener should do all this not on paper, but on a rotating circle, where to withstand exactly the size is even more difficult. But it is not enough to form it once. It is necessary that when repeated sharpening after sawing, the profile of the end of the circle is exactly the same as with previous sharpening, which is almost impossible. Therefore, it is not so important what quality you are sharpening around. Even if you have a very good circle and you can stand them without additional interchange of tape saws for a whole shift, you can almost never repeat exactly the same profile of the end of the circle in the following sharpening, which means that you will not be able to accurately set the profile of the teeth of the saw after her dullness. Now you understand why the exact formation of the end of the circle profile is not just a difficult, but an extremely difficult task. In order to somehow facilitate its decision, you can sharpen with bakelite reinforced circles with a thickness of 3-4 mm. But they are difficult to find the desired quality of manufacture.

Therefore, the profile of the circle must be monitored very carefully. Otherwise, this leads to the following changes in the body of the strip saw:

  • A change in the radius at the base of the tooth, which entails a change in the step and the impossibility of the next passage of the normal sharpening of the saw. The circle begins to unevenly crash into the front line, without touching the rear, or vice versa, that is, it becomes impossible to grind the full saw profile at once. For two or three passes, the sharpener has been trying to pave at least the cutting edges of the teeth, while a microhorb or microvpadin occurs at the place of transition, which lead to microcracks, and also do not remove when sawing microcracks, which leads to premature gap of the saw over the body.
  • Changing the angle of sharpening, tooth heights, shallow shapes that affect the productivity of sawmills and the quality of the resulting lumber.

Whole and at once

If you carefully read how the work is going in the first way, you should have understood how really it is really difficult to sharpen the saw high.quality.

There are constant conversations that it is impossible to quickly and well saw with narrow tape saws. The saws are torn quickly. For proper preparation, it is almost impossible to find a sharpener. Pilomaterial at the output is obtained with a large wave, which negates all the advantages of thin cut.

So, in order to radically solve all these problems at once, Wood-Mizer was offered a way to not consistent tagging of each tooth of the strip saw, and at once the entire tooth profile only one entry into it of a special specialized disk.

In this way, three main problems are solved at once:

  • No need to look for a highly qualified sharpener. on such a machine, almost any person can sharpen a saw on one pass with factory quality. He only needs to bring the disc to the saw. The rest of the machine will do it itself, which makes it possible to maximize the influence of the human factor on the quality of the result.If the profile of the saw tooth does not correspond to the profile of the sharpening disk, then at first the profiles of the teeth are formed over two or four passes, deepening the disk by one pass by no more than 0.1 mm. Further sharpening is in the usual order.
  • Ribbon saws operate two to three times longer, since the saw along the entire length is obtained with a completely protected and exactly the same profile of each tooth without bruises, micronerings and scs, that is, without voltage points.
  • Pylorama can work with its maximum performance, since the saw along the entire length is obtained with the same front and rear angles on each tooth. But, despite all the listed advantages, this method of sharpening was practically not used on sawmills for a long time.

This happened for the following main reasons:

  • Very high price. Therefore, such a machine was bought mainly by service centers.
  • Not very convenient technical solutions of the sharpening process itself. A warm room, special oil was required, only with which a weak oil pump could work. This oil began to burn with intensive sharpening, so a mandatory hood was required and much more.
  • But the biggest restriction was the inability to drag the profiles of tape saws of others, except Wood-Mizer, manufacturers, as Wood-Mizer made relevant discs only for its saws. There were no other manufacturers.

one. Cheap group Some manufacturers of classic sharpening machines simply change the phases of movement on a fist. Now the disk is already moving along the tooth, but only up and down. This gave them the opportunity when installing a profile disk to sharpen the entire tooth at once. But none of them understood that to sharpen a saw with a specialized disk, it was necessary not only to change the phases of movement of the fist, but also to make the whole machine in a different class of accuracy. Many of those who contacted us for help have already come across this. Therefore, I want to immediately warn about the meaninglessness of the acquisition of such machines. The worst thing for the disk is the backlash of the machine. If they are (and they are on all ordinary sharpening and, accordingly, remain on those sharpening machines that simply, with the help of another fist, try to convert to work with the Elbor discs), then the disk begins to be unpredictably beaten on the front line, then on the posterior, then on the posterior and accordingly and break the profiles of the teeth of the saw. Then the sharp ends of the teeth begin to cut the disk, several times reducing its service life.

Backlash can ruin the disk after 500 m. So it turns out from those who have already purchased such machines. At first, sharpening goes well, but very quickly, an expensive embrace disk becomes inoperative (it is simply cut to the base of the front part or risk is cut out). You need to buy a new disk, which is already becoming economically unprofitable.

In Fig. 3 shows the phases of the profile disk. He must enter into the profile of the tooth all at once and sharpen the whole plane. The thickness of the applied Elbor layer is only 0.25 mm. But this layer is enough for a long normal operation. If the front of the disk at the entrance to the profile crashes into the top of the tooth. then the sharp cutting edges of the teeth are relatively quickly pierced in risk coating or generally ripped off in this place completely to the base, making the disk unemployed. In this case, the breakdown of the tooth profile also occurs.

Dear group These are the manufacturers who simply copied the Woodser machine. At the same time, they got the machine at the price of the original, and the quality of manufacture is the same or even worse. With this option, it seems to me, it is better to purchase a proven original. However, this is already deciding.

Land machine with a borazon circle

A machine for sharpening tape saws with a borazon full.profile circle This machine is for sharpening in our service center.

Sharpening in this way is especially relevant when the saw on the tape-leading machines, since the saw there, unlike the pylors, works all the time, without stopping, and any non-converse voltage points there affect much faster.

However, this method of sharpening is now economically beneficial and when preparing a strip saw even on one sawmill.

Here is an approximate economic calculation of the payback provided to us by the owner of one of the pylors.

Обычный заточный станок. Примерная .

  • The salary of the sharpener is approximately 10-15 thousand. rubles a month. To prepare for one shift, 10 tape saws are required full time.
  • Small saw resource-sawing approximately 15-25 m 3 rounds on a trim lumber.
  • With poor or medium quality of the preparation of the saw, the productivity of the sawmill on the sawing of wood on the overlated lumber is usually 0.2-0.5 m 3 per hour of the round, that is, approximately 100 m 3 rounds per month.
  • The average cut 20 m 3 is multiplied by the number of saws (5 pcs.), we get 100 m 3.
  • We will take the average profit from 1 m 3 of the rubberized lumber equal to 400 rubles, with an average or poor quality of the surface and, accordingly, not the highest price for lumber.

Divorce devices

For a divorce, there are special divorce devices that are characterized by a wide variety and functional capabilities. Today, many experts are appreciated by the device for wiring “cedar” for its reliability, simplicity and ease of work, as well as a low price.

It is a manual machine that provides a wiring accuracy of 5 μm. The machine is equipped with special supporting racks to facilitate its use. The presence of an hour.long type indicator on the machine, the wiring accuracy increases as much as possible.

The carefully thought.out design of the Kedr divorce device provides a productive and efficient use of the entire saw resource set by the manufacturer. It can be easily configured for the necessary divorce parameters to ensure the optimal saw width. As a result, you can do with a lower engine power, t. to. friction forces are reduced when sawing.

This divorce machine easily and simply provides wiring in which the resistance of sawing is minimal.

Each of the wood of the tree has a characteristic rigidity. Depending on this characteristic, the pitch of the drain of the saw should vary. For hard breeds, the step should be less.

Despite the obvious advantages of this machine over other devices of a similar purpose, it has an affordable price, which also contributes to its increasing recognition in the vastness for wiring the cedar tape saws has the following technical characteristics:

Recall about simpler devices for divorcing saws. Their use for strip saws is fraught with low accuracy and great labor capacity. Their use is justified only in the absence of special devices.

Operation of tape sawmill

General information about the machine (ribbon sawmill spectrum-70) machine ribbon horizontal “Spectrum-70 ″ rice.1 (in the future in the text of the “tape sawmill”) is used to saw wood of any hardness on boards, timber, rail. Sawing is moving a saw frame with a cutting tool (strip saw) along a fixed rail guide of a tape sawmill. The use of tape sawmill allows: to make boards with high surface quality of material up to 700 mm. in diameter; Get a board with an accuracy of 2 mm. With a length of 6 m.; Ribbon sawmill allows you to reduce waste by 2-3 times, reduce energy consumption; quickly adjust the size of sawing, tape sawmill can saw short blanks (from 1.0 meters) and receive products up to 2 millimeters thick. The tape sawmill operates in the conditions of UHL 4 (GOST 15150-69). The ribbon sawmill is equipped. 2. “Ribbon sawmills”. work and device: 2.1 main nodes and parts of the strip sawmill: a bed that moves along the rail guides in a horizontal direction; Frame saw; The mechanism lifting the saw frame; Electric cabinet; Log clamp; Mobile slider of the driven pulley; The leading pulley; The pulley of the led; Wedge.rephid transmission; Rail guides of tape sawmills; A mechanism pulling the strip saw; Installation connector of the strip saw; Pulp of pulleys of tape sawmill tank tanks for crook guide saw a fixed guide saw, a movable ribbon pylorama, a shaped shape and sole with rollers of moving the saw frame on rails and felt brushes, which are cleaned of guide from sawdust. The lift of the saw frame is carried out by two sliders located on the racks of the bed. The movement is carried out by a bilateral, synchronously connected chain transmission, driven by an electric motor, through a gearbox. The frame has two channels, which are located in parallel and interconnected. The leading saw pulp is motionlessly fixed at one end of the frame, which has the possibility of longitudinal movement. The saw of the tape sawmill is pulled by the spring-screw mechanism, the spring damps the thermal expansion of the saw tape. In the manufacture of tape sawmill, a 35 centimeter.width tension is rated. The risks of the tensioner and the puck are equal to the tension force of 525 kilograms. In the front beam of the tape sawmill and on the slider of the driven pulley there are two locks for the picking and installing saw tape. On the brackets of the frame located in the middle of the frame, two guides of the strip saw (mobile and motionless) are installed, which are equipped with support rollers and the adjustment system and the bar. Twisting the moment is transmitted from the engine engine to the leading pulley. wedge.rephid transmission. Backet for coolant is fixed on top of the protection of saw schools. The supply of fluid is regulated by the taps located on the tank. The tape sawmill control panel is located on the upper jumper of the machine. Directed collapsible from 3 sections, which is convenient during transportation. Below are supporting plates into which anchor bolts are screwed. Top guides of the strip sawmill of the log of logs. The log on rail guides is fixed with four screw clamps and an emphasis that provides 90 degrees. 3. Fore pulp regulation The machine provides for the adjustment of the position of both pulleys in relation to each other in horizontal and vertical planes. It is necessary to ensure that the strip saw when tension is 6-8 kg/mm ​​kV. In the section on one branch did not go from the rims of saw pulleys. 3.2. First of all, the pulleys are adjusted in the vertical plane, exposing them at right angles in relation to the saw frame. To do this, on the slider of the driven pulley, the ML0 bolt is screwed from below to its axis, and on the leading pulley, adjustment is carried out due to the installation of seamy washers or plates. This operation.It is produced by the manufacturer. 3.3 To regulate the position of saw pulleys of the horizontal plane in the ends of the frame from the side of the leading pulley, two ML2 bolts are screwed, and one to the axis of the driven pulley is one. It is necessary to adjust the pulleys of tape sawmill in the following sequence: 3.3.1 Turn off the power supply machine on the control panel. 3.3.2 Open protective casings of saw pulleys. 3.3.3 install the strip saw on the pulleys so that it protrudes beyond the edges of the pulleys by a height of the tooth plus 2-5 mm. 3.3.4 Close movable connectors (locks). 3.3.5 pull the strip saw, turning the nut of the tension mechanism to the value of the optimal type for this type of ribbon saw (at the rate of 6-8 kg/mm ​​kV.). 3.3.6. Rotating with a hand for the driven pulley along the sawing (counterclockwise) you need to look at what position the tape saw will take on the pulleys. If the tape runs out to the equal size from both pulleys, then without weakening the saw tension, release the locking nut of the ML6, fastening the axis of the led pulley to the saw frame (slider of the saw frame). 3.3.7 Then release the M12 locknut and plunge the ML2 bolt to a small size, then tighten the M12 counter and the lock nut M16. 3.3.8 Repeat paragraph 3.3.6 and when the tape is running, repeat the adjustment until the correct result is obtained. 3.3.9 If the tape runs inside to an even value, then it is necessary to loosen the tension of the strip saw. 3.3.ten. Release the locking nut of the ML6, the M12 Ringia and turn out the M12 bolt to a small size, then tighten the m12 and M16 nuts and M16. 3.3.11 If the tape took the situation according to the instructions, then the adjustment is performed correctly. 3.3.12 If the strip saw immediately runs off the leading pulley, then the adjustment should start with it. 3.3.13 For this, depending on the direction from running the tape (outward or inside), release the left or right locks of the ML6 and adjust in the same sequence as on the ledness of the pulley. 3.3.14 after adjusting all the nuts tighten. 3.3.15 Close the doors of the casing of saw pulleys. 3.3.16 Turn on the email machine. energy on the control panel. 3.3.17 Turn on the drive of the saw pulleys briefly and make sure that the position of the saw tape is correct. The machine is ready to work. four. Requirements for saw tapes 1. During the operation of the strip sawmill, to increase the service life of the strip saw, it is necessary to carry out its proper tension on the pulleys. one.1 tension value, depending on its width, is determined by the “Tenzometer” device. one.2 attention! The strip saw should not be in the work for more than 2 hours. After this time, it should be removed from the machine and posted in a free state for at least 24 hours to relieve fatigue stresses. 2 Use the correct lubricant for the blade of the strip saw. As a lubricant-cooping fluid (coolant), in most cases, there is just enough water, or water with the addition of a detergent (“Fairy” and t.P.). However, at low temperatures, it is best to use a mixture of 50%.80% diesel or kerosene and 50%.20% of motor oil, or oil lubrication of tires of chainsaws. Good results in sawing coniferous rocks also gives the use of turpentine. In the case of using water as coolant, it is necessary to wipe the pulleys and tape with oil at the end of the work. 3. Always weaken the tension of the strip saw. When you finish the work, remove the tension from the saw. During operation, the blades are heated and stretched, and then when cooling, they are compressed to tenths of a millimeter during each cooling period.”Therefore, the tapes left on the pulley under load overload themselves, and they form a print from two pulleys, which causes cracks in the hollows between the teeth. four. Use the correct divorce of teeth. The divorce is correct if you have 65-70% of sawdust and 30-35% of air in the space between the canvas and the wooden wood. If you have too much divorce of teeth for the existing mass or thickness of wood, then there will be too many air in the propyle and not enough sawdust. You will have overly large losses on sawdust, and as a result, a large roughness of the processed wood. If the divorce is insufficient, you will not get a strong enough air flow to remove sawdust from the cut. A sign of this is hot sawdust. This can do the most destructive harm to the saw: working intervals will be short, the saw will fail prematurely. Sawdust should be cold to the touch. And finally, with insufficient divorce and improper angle of sharpening, the saw will cut out the wave on the board. From our point of view, you cannot work with the same wiring of teeth with logs of different diameters, drill forest and timber. You must sort timber. For every 20-25 centimeters of an increase in size, it is necessary to increase the wiring by about 18%, depending on whether the wood is hard or soft, wet or dry. The only way to achieve the necessary wiring is to carry out control cuts of a certain log. Increase wiring by 5-8 hundredths of millimeters on each side until you become, traces of teeth are visible. This means that you work with mixed air with sawdust in a ratio of 50/50. After that, reduce the wiring of the teeth by 8-10 hundredths on each side, and you will achieve the desired result. Please note: you must breed only the upper eighth of the tooth, not the middle or lower. You do not need that the cavity between the teeth is filled completely when sawing. When you work with soft wood, whether it is wet or dry, the chips increase in volume by 4-7 times compared to its condition at the cellular level. Solid rocks of wood, wet or dry, increase in volume only 1/2-3 times. This means that if you saw 45 centimeter pine logs, you will need to dilute the teeth 20% more than when you work with 45 centimeter oak logs. Always make teeth before sharpening. 5. Take the saw correctly. There is only one way to sharpen tape saws. The stone should pass along the surface of the tooth down, around the base of the hollow between the teeth and up along the back of the tooth with one continuous movement. You must save the profile of the tooth and interdental cavity. The space between the teeth (galllet) is not a litter for sawdust. The power flow of air, cooling of steel and the removal of sawdust depends on it. If you have the correct divorce of the teeth, the air is supplied along the log at the same speed as the saw, as a result of the sawdust, are sucked into a gall. Sawdust significantly cool it, passing around the inner and outside of the next tooth. It is necessary that the space between the teeth is filled by 40%, which will provide the necessary cooling and increase the operation of the saw. 6. Install the correct angle of sharpening. Thanks to deep gallets, we can use the reduced sharpening angles that transmit less heat to the tip of the tooth. The ribbon series uses an angle of inclination of a hook of 10 degrees, which is able to penetrate into most surfaces of wood from medium hard to medium soft. The general rule is this: the harder the wood, the smaller the angle of sharpening. Caution: Do not trust the scales and measuring ruler on your machine machine! Pins and guides wear out on it. In the process, the profile of the stone changes. To control the correct angles of sharpening, use the transporter. Attention; We recommend changing saws every two hours of continuous work, letting them rest at least a day. During the operation of the machine, there is a need to regulate individual components in order to restore their normal operation. In Fig. 1 shows some parameters of the canvas that determine its durability and performance where: a is the angle of sharpening, this is the angle between the front surface of the tooth and the plane of the perpendicular back of the saw; B. tooth cavity; C. the back surface of the tooth; E. divorce, this is a deviation of the tooth from the vertical. Fishing line for a trimmer of divorce (place of bending) is located at a distance of 1/3 from the top of the tooth; R is the radius of the hollow;

The first drank

Important is the choice of the edge of the sawing wood to start processing. When sawing a timber and circular processing, the masters use 2 methods.

The worst line is the first to cut the first, the tag of the log is not taken into account. Taking into account such a feature means tilt, raising the log so that the saw works parallel to the bark. Short boards and a large number of humps will come out of this part.

Since the conical is not taken into account, on the best edge of the log, sawing will go parallel to the bark without tilt and lifting, this approach will allow you to get a maximum of long boards of good quality.

Drawing boards of different cuts

Start with the best edge of the log, but the cones to take into account. That is, set a log so as to direct the saw parallel to the bark.

The result will turn out the same, but in the second method the sawing worker is easier to choose the best line, as it is visible. In the first method, the best part is hidden and inaccuracies are possible when installing a log. If the sawn wood of high quality, both methods work the same. With lower quality raw materials, it is better to use the second method.

The strip saw is a fairly common cutting equipment that is used to process various materials. Only with proper preparation and maintenance of such equipment can one count on the fact that it will work correctly and for a long time. To do this, you may need an automatic divorce machine for strip saws that can be purchased or created with your own hands.

Divorce and sharpening procedure

When choosing a strip saw for organizing production activities by processing wood, a lot of attention is paid to what characteristics the saw has: size, material of the cutting edge, production technology, and so on. However, it is worth remembering that, regardless of the type of cutting element, divorce and sharpening have to be carried out periodically. Homemade raising saws for ribbon saws

To begin with, we note that a home.made divorce machine for strip saws is extremely rare.

This is due to the points below:

The efficiency of equipment depends on the correctness of sharpening and divorce. If the work was not done correctly, then sawing can take place with the rapid wear of the teeth.It is important to work with maximum accuracy. Modern models can sharpen and wiring with an accuracy of 0.1 millimeters. Such high accuracy allows you to simplify sawing, make it more smooth.Depending on the workload of the production line, the procedure has to be carried out with a large frequency. Therefore, a divorce machine for strip saws should work quickly, the entire process is automated if possible, which also eliminates the likelihood of marriage when performing work.

Recently, a double.sided divorce machine for ribbon saws of various manufacturers has been increasingly using. The wave during sawing and why it is not when the saw is divorced on RS30/60.

Industrial equipment

On sale you can find a fairly large amount of equipment that can be used to solve the problem of bringing the geometry of the saw to the correct indicators. An example can be called an imported engine for Silicon Setting Machine tape saws or a Wood Mizer double.sided machine.

When choosing equipment, attention should be paid to the following points:

Producing country. As a rule, equipment of imported origin is more expensive, but its quality is significantly higher. Among domestic representatives, one can distinguish a tiega double.sided machine, which has a relatively low price and high quality manufacturing.The width of the saw. Each model of astronomer or taiga, another manufacturer, has a range of possible width of the cutting tape, which is usually indicated in millimeters.There are several types of saws. When buying, you should pay attention to the fact that the selected equipment should be intended to work with the ribbon type of saws.Wood Mizer Divorius Two.way can operate in manual or automatic mode.Considering the Taiga Vigati or RWM RWM Divorce machine, you need to pay attention to the principles of work. The most common and popular can be called a design that is designed to breed 2 teeth at the same time.In addition, when choosing a manual or automatic divorce machine for strip saws, attention should be paid to the power of the installed engine. Not only performance depends on this, but also electricity costs. The manufacturer also indicates the mass of the structure, which determines the presentation of the requirements for the installation. A double.sided divorce machine for strip saws can weigh about 200 kilograms.

Is it worth making a homemade dumping machine for strip saws. a fairly common question.

Note that a home.made version of the performance will not have the desired accuracy class, and the work on sharpening and divorce of the teeth will mean not effective.

Features of setting

Setting up a tape saw of tape saws is carried out depending on the features of its design. If we consider several models of the equipment in question, then you can pay attention to the fact that it is constructively different. Some compact, others have large control units.

Considering how to configure a divorce machine for strip saws, we note that it is important enough to consider the saw width and the step of the tooth, its height. It is these parameters that are taken into account when setting up the equipment in question.

Rules for sharpening tape saw on wood

Ribbon saw. a closed.type cutting tool used on sawmill equipment.

The unconditional advantages of these elements are high performance and minimum amount of production waste. It is possible that when sawing ordinary boards, the last fact does not play a significant role, but if we are talking about processing wood of valuable species, the width of the cut and the quality of the cut directly affect economic benefits.

Proper sharpening of wood tape saw is a guarantee of the effectiveness of production and durability of the tool. Typically, such services are provided by specialized companies, but if you know the procedure and subtleties of the procedure, you can sharpen the blunt saw yourself.

  • Characteristics
  • What you need to know about the angles of sharpening teeth
  • How to sharpen a strip saw
  • Wiring
  • Sharpening


Three distinctive features are characteristic of strip saws. They are made only of special varieties of instrumental steel, which provides high indicators of strength and wear resistance of teeth. Manufacturers usually use steel of 9XF and B2F categories, foreign companies prefer the C75 series. In any case, the hardness of the material should be at least 45 HRS.

The width of the cutting of the canvas of the tape saw is much already already than that of disk analogues. As mentioned above, this is a fundamental factor in the processing of valuable wood and business wood.

Saws can easily cope with blanks of any length and diameter. At the same time, a properly sharpened strip saw provides high production productivity.

It must be clarified that the reliability of closed saws is explained by the heterogeneity of the material that is used to make the canvas.

In particular, the body of a saw instrument is usually made of spring steel, which has incredible resistance to stretching and dynamic loads. Varieties of steel with a high molfram and cobalt go to the manufacture of the cutting edge. Individual parts of the canvas are welded to each other with high.frequency currents. Tools made using this technology can be used to saw metal.

What you need to know about the angles of sharpening teeth

The geometry of the teeth of tape saws can be modified depending on the characteristics of the processed material. This is expressed in the shape of the tooth and the distance between the individual elements of the cutting edge.

The profile of the strip saw is determined by the marking that the manufacturer applies. It looks like this:

  • WM is a universal version designed for sawing soft and solid wood;
  • AV. is used for longitudinal cut and sawing of solid materials, such as frozen wood;
  • NV. is distinguished by a narrow width of the canvas, so it is ideal for curly cutting;
  • Nu is a cutting edge with a wide pitch of teeth, which provides high performance when sawing soft wood;
  • PV is an almost complete analogue of the previous canvas, but has a flattened shape of the teeth;
  • KV. the profile is used for wide strip saws intended for soft wood;
  • Pu. a wide saw for sawing solid wood.

The step of the teeth is selected individually, depending on the material. For example, for sawing solid wood and metal, only fine.toothed canvases are used to avoid damage to the cutting edge. Soft raw materials and thick.walled materials are treated with saws with a large distance between the teeth, which allows you to accelerate the production process.

How to sharpen a strip saw

Immediately note that if there is no experience and skills of performing such work, it was better to entrust the sharpening of sawing professionals. Violation of the geometry of the teeth of the cutting edge, the appearance of scale on the metal or incorrect wiring significantly reduce the life of the canvas.

Having decided to sharpen the strip saw with your own hands, it will be useful to first familiarize yourself with key definitions, the knowledge of which may be required in the process. So, for the correct formation of the cutting edge, it will be required:

  • wiring. deviation of the teeth from the plane of the main canvas of the saw;
  • tooth height. the distance between the upper point and the base;
  • Step-the distance between the teeth, usually varies within 19-25 mm.
  • angle of sharpening. depends on the target purpose of the tool; For example, the recommended angle of sharpening of the carpentry is 35 °, dividing-18-22, designed for sawing a beam-no more than 15 °.

The angle of sharpening is determined by the manufacturer, therefore, with independent editing of the saw, it is recommended to adhere to these parameters.

Let us give a detailed instruction that will help to properly sharpen the closed saw without resorting to the services of specialists.


Divorce of tape saw on wood. this is the first stage of restoration of the profile of the cutting edge. During operation, the location of the teeth may change, so the proper geometry has not yet been achieved, it makes no sense to grind the saw part.

  • classic. teeth alternately deviate into the right and left side;
  • cleanser-1st and 2nd teeth deviate in different directions, the third remains even. This profile is created for sawing solid materials;
  • wavy. the most difficult option resembling a wave in shape. Here, each tooth is given an individual form, and this type of wiring is usually performed only in specialized workshops.

It should be noted that during the wiring, not the entire tooth is enveloped, but approximately 2/3 of the upper part. The procedure is performed on a special machine for wiring tape saws. The cost of such a tool is quite high, because it is bought if you need to establish several tools. Its availability may become the basis of the sharpening business.

Of course, the first time everything may not work correctly on the first time, therefore, at least the profile geometry should remain the same as before the start of work.


This is the main stage of editing the cutting edge, which can be performed in two ways.

Full.profile sharpening of the saw is performed by the Elboron Circle installed in a special sharpener machine.

Features of sharpening tape saws

If you use a strip saw, keep in mind that it is not difficult to sharpen it yourself. At the same time, you do not have to pay for sharpening services provided by specialized workshops.

Basic information about ribbon saws

The strip saw is a cutting tool made in the form of a gear tape having a closed circuit. Its maintenance needs a special sharpening machine for strip saws. In addition, ribbon saws have a number of other significant differences from traditional disk models. The most significant of these differences is the ability to get a cut with a minimum width using such a tool. It should be noted that this is especially true when it is necessary to cut wood of valuable rocks and blanks of expensive metal.

Equipped with a strip saw can be successfully used to process parts made of different materials and having various configurations. Such processing is characterized by the minimum amount of waste of the processed material, exceptional cut quality and high process speed. However, such processing parameters can be achieved provided that the sharpening of strip saws on the machine is performed not only correctly, but also regularly. When servicing a strip tool (especially if you deal with this on your own), you must strictly adhere to the recommendations of qualified specialists.

Ribbon saws, depending on the characteristics of the processed material, can be made of different materials, differ in the geometry of cutting teeth. If we talk about the separation of metal blanks, two stamps used for the manufacture of saws: 9XF and B2F are most widespread here. Equipment for sawing wood is equipped with saws made of tool steel, the hardness of which on the HRC scale is at least 45 units.

Ribbon tools for sawing wood are additionally divided into three types: carpentry, dividing, for processing logs. Tools related to different types, of course, have different parameters (the dimensions of the canvas, shape and angle of sharpening). The stronger wood of wood is treated with a tool with a smaller angle of sharpening.

Today, bimetal.type ribbon saws are increasingly used, which are necessary to separate the blanks made of solid varieties. Such saws are called bimetallic because they consist of two different metals: cutting teeth. of steel with a large molfram and molybdenum, and the canvas itself is made of spring steels. Of course, such canvases are much more expensive than standard models, since they need special equipment in which the connection of two heterogeneous metals occurs under the influence of an electronic beam.

Types of stripping ribbon saws

Like any other tool, the strip saw is worn after each cutting cycle. This is a natural and inevitable process. That is why each drain type saw needs regular and qualified maintenance. wiring and sharpening. Such maintenance allows not only to maintain a cutting canvas in working condition, but also to significantly increase its life.

Increase the service life of the cutting canvas and significantly improve its functionality allows the correct wiring. The meaning of this operation is as follows: the cutting teeth of the saw bend in different directions, which allows reducing the friction force during cutting, as well as minimize the risk of closing the canvas with a processed part. Warring the strip saw can be performed according to three schemes, the choice of which depends on the type of material processed.

  • With the so.called cleaning type of wiring, the teeth are bent in such a way that every third of them remains untouched. Such a scheme is used if the cutting canvas is used for the cut of particularly solid metals and alloys.
  • The classic type of wiring involves an alternate extension of each cutting tooth.
  • With wavy wiring, each cutting tooth is bent to a certain angle. It is clear that this type of wiring is the most difficult of all others.

To bend the teeth of the strip saw, special equipment is used to perform such a technological operation quickly and as accurately as possible. According to generally accepted standards, the maximum wiring of the teeth should not exceed 0.7 mm, but usually its value is in the range of 0.3–0.6 mm. It is important not only to choose the type of wiring, focusing on the characteristics of the material that has to be sawed, but also to perform it correctly, bending the teeth only by 1/3 or 2/3 of their heights.

After wiring, you can send a cutting canvas to a machine for sharpening tape saws. As statistics show, tape saws most often lose their functionality due to the fact that their sharpening was done incorrectly or untimely. The indicator that the strip saw needs wiring and further sharpening on the machine, is increased roughness of the surface of the saw. The need for such a procedure can also be determined by the appearance of cutting teeth.

The main elements of any grinding machines are circles, the choice of which, first of all, depends on the hardness of the material used for the manufacture of cutting teeth. In order to sharpen hard materials, it is necessary to use the corresponding circles. So, for sharpening with bimetal.type paintings, sharpeners consisting of borazon or diamond elements are chosen, and to put the saw made of instrumental steels in order, corundum circles are quite suitable.

Tools for sharpening the ribbon.type saws are chosen both in composition and in constructive performance. For different in design and the size of paintings in machines, circles of the following types can be used:

A set of Wood-Mizer devices for sharpening and wiring tape saws

Pilla wiring methods

The second mandatory operation to prepare a saw for work after sharpening is their wiring. From a technical point of view, it consists in bending the teeth to the sides of the required angle. The meaning of this procedure is to reduce the friction force between the teeth. This allows you to ensure the free movement of the tool canvas on the sawing surface.

The most common peel is the standard. With this method of wiring, the saw link is bent in different directions at a distance of no more than 0.4 mm. It is quite possible to carry out such wiring at home, while it will be necessary to check that the angle of deviation of the teeth is the same.

Another type of wiring is protecting. It is usually not used at home, t. to. To do this, bend 2 teeth in different directions, leaving the third in place. In terms of difficulty with it, wavy wiring is similar. Here the links of the canvas are bent in one direction, while creating a kind of “wave” on the canvas. Only an experienced master can perform these types of turning, so in everyday life they are practically not found.

When engaged in this work, it is necessary to remember that different types of saws require an individual approach.

In this regard, it is necessary to carefully study the instructions for the operation of a saw of one or another. In particular, this document indicates the density of the metal of the canvas, as well as the recommended angle of deviation of the teeth. It is usually equal to 30-60%, although for some products it can be increased.

Selection of a saw master for sharpening

T. to. The ribbon saw intended for the cut of a large volume of wooden products is almost impossible to dilute and sharpen it independently, the question arises with the selection of a specialist who will carry out such a job. It will be better if he does these work on a professional machine. Therefore, be sure to clarify this moment by placing your order.

In addition, the master should be able to perform all types of sharpening and wiring, and not just the simplest. This will allow you to save your tool from premature wear and get a quality incision. If the master tells you that there is only one type of sharpening. immediately refuse his services, t. to. He is not a professional.

This professional must have a corresponding certificate. You will have to focus on its presence or absence when selecting a specialist in sharpening tape saws.

Types saw

Ribbon saws can be distinguished by the type of teeth, taking into account the configuration of which the necessary sample for processing material of a certain type is selected. The selection of saws of the saw tooth teeth is based on the characteristics of lumber, in particular, on the parameters of its hardness: the denser the wood, the smaller the front angle of the tape incisions and the step between them.

Observing this rule, it is possible to significantly improve the quality of the rapids and extend the operational period of the tool.

The sawing of thin materials is usually carried out using a saw canvas, which has a standard or small step between the cutters, otherwise the risk of damage to the working tool increases repeatedly. The saw with a big pitch of the teeth is designed to cut metal or wooden thick.walled blanks with it, which must be fixed tightly before proceeding with the processing process.

Working rules

If you decide to sharpen the strip saw at home without resorting to the services of a specialist, read the rules for performing this procedure.

To perform the correct pointing of the strip saw, you will need a special sharpening machine and the instructions given below. The configuration of the sharpening circle, which can be flat, profile, plate or made in the form of a bowl, is selected depending on the technical characteristics of the saw. We draw your attention to the fact that strict adherence to safety rules will protect you from injuries, and the tool from breakdown. To protect the respiratory tract from characteristic heavy dust, work must be carried out in a respirator or a special mask. So, let’s move on to the phased performance of the work.

  • Starting to sharpen the strip saw, be sure to check the sharpener for uneven abrasion and all kinds of defects, the presence of which will not allow the removal layer of metal and lead to undesirable consequences in the form of damage to the cutter.
  • To tighten the dull tool without jerks and a sharp movement of the tool on the surface of the abrasive circle, otherwise the structure and height of the teeth will be broken.
  • The third rule is more likely to concern the mechanism of the grinding circle, which should contain a coolant that prevents the overheating of the unit. Such an option will protect the sharpener from failure and will help to carry out accurate sharpening of a saw blade.
  • Upon completion of work, you must carefully inspect the surface of the saw and make sure that there are no hooks and chips on it. If such defects are detected, the saw must be sharpened on the circle again, bringing it to the machine at a certain angle, or bring to the necessary parameters on a grinding machine.

Turning methods

Sharpening of tape saws on wood is performed in two ways: on professional equipment (full.profile) or by focusing faces of incisors. In the first case, we are talking about the most accurate machine of sharpening, during which the entire process is carried out using automation. In order to sharpen the tool properly, here it will be enough to choose the main element of the machine. the Elbor Circle, everything else is controlled by electronics. The cost of such work is quite high, and it is hardly suitable for those who often face the need to sharpen the saw due to their intensive use, unless, of course, the master owns such a machine. It is worth noting the fact that buying a set of abrasive circles for all types of tape saws also requires additional costs, and for one.time manipulation there is no sense in acquiring it.

The second method involves exclusively sharpening of the teeth, and can be performed both in manual and automatic mode using a special device. For proper manual sharpening, the presence of an engraver and certain skills of a person who works with him is required. In order not to spoil the metal and avoid damage to the teeth, the movements of the master must be accurate and fast enough. For the first time proceeding to such procedures, it is advisable to carry out a trial sharpening on an unnecessary sheet of metal to avoid damage to an inconsistent tool.

Proper sharpening of tape saw canvases involves the processing of the rear and front faces of the incisors, although most masters performing this process manually are limited exclusively by pointing the rear edges. This method will allow the use of the tool for its intended purpose, in addition, it is implemented much easier than double.sided sharpening. The focus of the front edges can be carried out correctly in the presence of a sharpener machine. Here, as well as in the case of full.profile sharpening, it is necessary to choose the right size of a sharp.circled circle, and then the cutting tape will gain the necessary sharpness. There is a winter method of focusing the tape, in which the angle of sharpening is 90 degrees, and instead of water, a coolant or diesel fuel is poured into the machine.


Unfortunately, standard sharpening is sometimes not enough to return the saw the necessary degree of severity, an important condition of which is the size of the cutting of the incisors, called in the professional language wiring. The essence of this condition is that at the time of sawing when the tool is in contact with lumber, the friction force is reduced, and the material could freely move between the teeth of the canvas.

In most cases, standard wiring is used, during which alternating extension of the incisors in different directions relative to each other is about a distance not exceeding 0.4 mm. It is quite possible to breed a saw at home, while it is necessary to exercise strict control over the angle of deviation of the cutting elements. it should be the same.

There is also a protective wiring to which they resort mainly in professional workshops. With this procedure, two incisors should be bent at different angles, while the third tooth remains not touched. No less complicated is wavy wiring, and its essence is fully reflected in the name. In this case, the teeth are delicately bent in one direction and close tightly, and the tape acquires a wavy configuration. In the video you can see how ribbon saw is carried out at home.
