Sharpening Of Band Saws For Metal

Setting the cutting elements of the band saw

Divorce is the bending of band saw blades in different directions. This significantly reduces the friction of the blade and prevents it from pinching. To ensure free movement of the blade against the walls of the material being cut, its width must be greater than the thickness of this material.

Band saw set types

Divorce can take several forms. It may have different names from different manufacturers. Most often it can be:

• Standard, which is characterized by the opposite bending of the cutting elements in various directions. It is most commonly used for band saws that cut hard material.
• Wavy, which belongs to the category of complex structures. Divorce in this case has a variable meaning. In this case, a kind of wave is formed.

Divorce consists in folding not the entire canvas, but only a certain part of its top. The parameters are determined strictly by the tool manufacturers. Their range is 0.3 to 0.7 millimeters.

Protecting. The divorce consists in bending two teeth. In this case, the third remains in place. Designed for band saws for extremely hard material. In shape, every third tooth resembles a trapezoid. The location is the center of the canvas. With its help, the most correct direction of the saw band is carried out.

Woodworking machines are characterized by a versatile sawing tool design. The spread for soft rock processing must be larger than for hard rock equipment. But the divorce should not be such that the wedge is located in the center without a cutout. The divorce must be characterized by the same arrangement of all cutting elements. It is necessary to spread the teeth in such a way that the deviation is no more than 0.1 millimeter. If the saws are unevenly positioned, this will lead to the fact that the band saw equipment will move to the side during operation.

Saw band design

Band saws are a special continuous design characterized by the presence of cutting elements on one side. This is the cutting element with which woodwork is done. Most often, band saws are used in a variety of band saw blades. With their help, cutting of various parts is carried out. With the help of these blades, a sufficiently high cut quality is ensured. All this is provided only if the saw has a good set. Also, the tool must be serviced in a timely manner.

Band saws are made of heavy-duty metal, which ensures not only high cutting quality, but also the saw’s durability. The teeth have a universal angle, which allows for the highest quality cutting of the material.

Sharpening and setting band saws

In order for the processing of various materials to be carried out correctly, it is necessary to look after and monitor the condition of the band saws. For this purpose, machines are used for sharpening and setting band saws. Timely care will ensure long-term use of instruments.

Shapes of the cutting part and the angle of sharpening of blades

The geometry of the cutting elements of band saws can be varied, which directly depends on the material that is intended for cutting. Woodworking machines are most often equipped with special saws, with which you can carry out:

• Carpentry work;
• Sawing logs and beams;
• Use on dividing saws.

The sharpening angle is determined strictly by the tool manufacturer. The rake angle will be as small as possible when using hardwood. Band saws for metal are equipped with saws with different blade shapes, which directly depends on the metal used for sawing. If it is necessary to cut thin-walled metals and at the same time have thin chips, the rake angle when sawing will be equal to zero, then standard cutting is used. The sharpening angle can be varied. It directly depends on the structure of the device.

A tooth that has a positive rake angle is found in saws commonly used for cutting thick-walled metal. The step of the blade, with the help of which the sawing of thin metal is carried out, is rather small. In order to cut thick-walled metal, it is necessary to use devices that have a large number of blades. In some cases, the equipment has a variable pitch to eliminate the resonance effect. The change in the distance between the teeth directly depends on a certain group.

Sharpening recommendations

During the work of the canvas, its break is very often observed. This is due to the fact that it is poorly sharpened. This is due to the concentration of stress in the blade profile, if the sharpening is carried out at a low-quality level. The need for the procedure is determined by the condition of the band saws. If the surface roughness of the cut increases, this leads to a blunt tool.

Sharpening of the tool is carried out using diamond, electrocorundum, CBN discs. Their choice directly depends on the characteristics of the material being processed. The sharpening of the blade, the production material of which is tool steel, is carried out with corundum wheels. The procedure for bimetallic tools is carried out correctly if a diamond or CBN wheel is used. The instructions will tell you how to carry out this procedure. The most important thing is that the angle does not change in the process.

Wheels of various diameters can be used for sharpening. The choice of one of them is determined by the parameters of the device. For this purpose, profile, flat, dish-shaped, cup circles are most often used. Sharpening is correct if the peripheral speed is 20 to 25 meters per second.

The principle of sharpening tape blades

If there are chipping on the tool, chipping will be observed on the edge of the workpiece. That is why it is imperative that sharpening is carried out correctly. During this process, it is necessary to work not only with the front, but also with the back of the canvas. Sharpening devices can be carried out in different circles. In this case, it is necessary to take into account the angle of the canvas. If you want to carry out the procedure correctly, then you need to learn it from a specialist.

In order for the band saw equipment to work efficiently, it is necessary not only to select it correctly, but also to sharpen it in a timely manner. For this purpose, special circles are most often used. This procedure is as simple as possible, which allows it to be easily performed by a master without appropriate experience.

2 Setting and sharpening band saws is the essence of the process

The cutting edge of the tool loses its properties after each use for its intended purpose. It is impossible to correct this situation, the natural wear of the saw during operation is considered inevitable. In this regard, the wiring carried out before sharpening the cutting attachment and the sharpening itself have a great influence on the functionality of the tool.

Set is the procedure for bending the teeth of the cutter to the side to reduce friction on the blade and prevent it from pinching. This operation is performed in three ways:

• Stripper: every third saw tooth is left in the starting position, this setting method is recommended in cases where the band saw machine processes very hard alloys and materials;
• Classic: alternate bending of the teeth to the left and to the right;
• Wavy: the most difficult type of procedure, in which the bend rate of each hotel tooth is highly individual.

Wiring is carried out by means of adjustable special devices. Its value, as a rule, does not exceed 0.7 mm (in practice, teeth are divorced by a smaller amount. from 0.3 to 0.6 mm). Note that 2/3 or 1/3 of the tooth is folded back, not the entire tooth.

After a well-done wiring, you can send the tool to the band saw sharpening machine and start sharpening it. It is known that more than 80 percent of cases when a saw loses its operating parameters is associated with improper sharpening or the fact that it was not done in a timely manner. It is not difficult to determine the need to perform the procedure visually. by the increased roughness of the saw cut walls, or by the type of teeth.

The hardness of the teeth directly affects which wheels should be fitted to the band saw sharpener. For bimetallic devices, borazon or diamond wheels are usually chosen, for tool steels, corundum wheels. But the shape of products for sharpening is determined by the characteristics of the saw. From this point of view, circles can be:

When sharpening teeth, you must adhere to the following mandatory requirements:

• Burrs should not appear;
• Metal removal along the tooth profile should be uniform;
• Use liquid to cool the sharpening unit;
• The profile of the tooth and its height should not change as a result of the procedure;
• Excessive pressure on the wheel is unacceptable, since in this situation there is a high risk of annealing formation.

Before sharpening, it is advisable to leave the tool in an inverted suspended state for 10–12 hours. This will greatly facilitate the process.

In most cases, home sharpening is performed on the back surface of the saw teeth, although the manufacturer’s recommendations allow the operation to be performed on the front surface.

Saw band cutting

There are several types of wiring, the names of which may differ from different manufacturers. Basic types.

Sharpening of band saws for metal. Metal Band Saw Sharpening

Saw band sharpening

The low cut width results in relatively low energy consumption for cutting material. And finally, with a band saw, you can cut a workpiece of almost any thickness, while the geometry of the circular saw limits the thickness of the material it cuts. However, to reap all these benefits, band saws must be able to properly prepare for the job. The main preparatory operations are sharpening and routing of band saws.

1 General information about band saws

Such saws, which are closed-type toothed band saws, are understood as the cutting tool used in various band saw installations. They have a number of differences from disc cutting devices.

This is important in cases where valuable wood species and expensive metal are processed.

With band saws, you can cut any part. At the same time, their use guarantees minimal chip waste, excellent cut quality, and a fairly high speed of work. But, all these advantages can be personally verified only if the sharpening of the band saw is performed regularly and competently. In other words, the tape tool will perform its tasks efficiently with its timely maintenance in accordance with the recommendations of specialists.

The geometry of the teeth of the saws we are considering is different. It depends directly on the mechanical and other characteristics of the material to be cut. As a rule, for the processing of metal blanks, tools are used from steel 9HF and B2F, wooden ones. from tool steel with an HRC of at least 45.

over, saws for wood are additionally divided into dividing saws, carpentry, for sawing logs. Each of these tool subtypes has its own tooth configurations and overall dimensions. The sharpening angle of such saws is set taking into account various factors. The main trend in this case is that the rake angle of the tool is made the smaller, the harder the wood is to be cut or sawn.

Often, bimetallic band saws are used to cut metal parts. In them, the tape with teeth is made from compositions in which tungsten and molybdenum are present in sufficiently high quantities, and the blade is made from spring high-speed steels. Such devices are more expensive than standard devices in terms of their cost, since the technology of their production is very laborious. It involves using an electron beam to connect the base of the tool to solid steel.

Saw material

Wood sawing machines are made of tool steel with a hardness of 40-45 HRC. Domestic manufacturers use steel 9HF, B2F (for band saws for metal), etc., foreign. Their steel (C75, Uddeholm UHB 15, etc.). When extinguishing the teeth of such saws with high-frequency currents, they can acquire hardness up to 64 HRC and higher.

Saws for cutting carbon steels and non-ferrous metals of small thickness are also made of tool steel with obligatory hardening of teeth by high-frequency currents. However, more often for cutting metal, bimetallic saws are used, in which the blade is made of spring steel, and the strip on which the teeth are cut is made of high-speed steel with high tungsten and cobalt. After hardening, it acquires hardness up to 65-69 HRC. High speed steel electron beam welded to the saw blade.

Bimetallic saws are capable of cutting thick metal from tools, stainless, heat-resistant and other steels, titanium alloys and other metals.

Teeth with greater wear resistance are obtained by fusing them with stellite (an alloy based on chromium and cobalt with additions of tungsten and / or molybdenum) or by soldering carbide plates to them. Such saws are superior to their bimetallic cutting ability. They are used to cut fiberglass, tires, cables, reinforced plastics, high temperature alloys, graphite, aerated concrete, bricks and other difficult cutting materials.

Band saw geometry

Three types of teeth are used for sawing wood: for carpentry, for separating saws, for sawing logs and logs.

The specific values ​​of the sharpening angles of band saws are determined by manufacturers based on a number of factors. In general, we can distinguish such a dependence. The harder the wood, the smaller the rake angle (γ).

For metal saws, a different tooth shape is used depending on whether they are for cutting metal. Constant pitch saws distinguish between two basic shapes.

Standard, designed for cutting thin-walled metal with short chips with a rake angle (γ) of 0 °.

Positive rake (γ) tooth used in long chip saws for cutting thick walled metal.

For thin walled material, use relatively fine pitch saws (teeth per inch, 4 to 18). Saws for cutting thick-walled material do not require a lot of teeth, their number is 1.25-6 teeth per inch.

To eliminate the resonance effect that leads to blade vibrations, some saws are made with variable pitch, in which the distance between the teeth changes in a separate group. The step size is indicated by the largest and smallest values.

How is band saw sharpening

When sharpening band saws for metal, the first thing to check is. This is the correct setting of the sharpening machine (position of the sharpening disc relative to the saw). The sharpening device has a special device for this purpose. If you do not have it, then you need to check the perpendicularity of the plane of the sharpening disk to the saw, and what is very important. the alignment of the disk and the plane of the saw.

Sharpening the saw is needed not only to sharpen the cutting edge, but also to remove numerous microcracks that have formed in the sinuses of the teeth. Most often, their greatest number is formed in a place equidistant from the ends of the teeth. For saws, this is the narrowest part of the saw.

A few words about the band saw sharpening specialist. The candidates for this position must be selected with the utmost care. It should be a diligent and conscientious worker, trained, meticulously following all points of the sharpening instructions. If you have such a person, then the problem of breaking saws is familiar to you only by hearsay. If you have not found such a specialist, we recommend purchasing a sharpening machine with a borazon disc. this will reduce the dependence of the sharpening quality on the human factor.

When sharpening band saws, it is important to remove such an amount of metal from the sinuses of the teeth so that microcracks are removed along with it. over, the metal should be removed evenly along the entire tooth profile. Failure to comply with this condition, in addition to increasing the risk of saw breakage, also leads to a change in the saw parameters (saw profile and tooth height).

If the saw has been in operation longer than recommended by the manufacturer, the amount of metal removed in one sharpening must be increased. When performing this operation, make sure that the pressure of the sharpening wheel on the saw is not excessive. Otherwise, annealing of the saw blade will occur, reducing its strength characteristics. And it is absolutely unacceptable to sharpen the saw without using a special coolant in the saw sharpener.

Sometimes, even if a small amount of metal is removed, annealing still occurs. In this case, it is necessary, using a dressing stone, to clean the working surface of the grinding wheel from metal particles covering it during the sharpening process. This operation must be repeated after the saw has gone through one sharpening cycle.

After sharpening band saws for metal, check the result (profile, geometry) using a new saw as a reference. If the saw is sharpened correctly, its profile does not change, the height of the tooth remains unchanged, there are no rough risks from abrasive particles of the grinding stone in the axes of the teeth and at their tops, there are no traces of metal annealing, the burrs are completely removed, the cutting edge of the tooth has the correct shape and sufficient sharpness.

Sometimes you can find recommendations that there is no need to carefully remove the burrs after sharpening. This is not true. The fact is that, in addition to distorting the wiring results, burrs provoke the formation of microcracks in the saw blade.

Sharpening band saws for metal

Sharpening band saws for metal is essential if you are working on a band saw. During operation, the saw teeth gradually wear off, which affects speed and overall productivity. Therefore, periodic maintenance is required, which boils down to setting the teeth and sharpening them. Thanks to the timely implementation of such work, it is possible to significantly extend the life of the cutting tool. But at the same time, you still need to know how to properly sharpen the band saw. Failure to comply with the sharpening technology leads to the fact that further use of the tool will be impossible.

First, let’s consider the possible reasons that can lead to a decrease in the efficiency of the band saw:

• The saw teeth point in the opposite direction to the blade rotation, i.e. The blade is installed back to front. Install the blade correctly. Turn the saw inside out if necessary;
• The canvas was not run in (rolled in) or was run in incorrectly. Run in the saw band correctly;
• Solid inclusions in the material. Check the hardness of the material and the presence of solid inclusions (scale, traces of flame cutting.);
• The material was subjected to strain hardening. Increase the supply pressure;
• Wrong choice of coolant. Choose the right coolant;
• Incorrect cutting fluid concentration. Check oils in coolant;
• The web speed is too high. Set the blade speed according to the material;
• Insufficient supply pressure. Increase supply pressure.

Band saw blade

A few words about the grinding wheel. Savings are inappropriate here. By using cheap grinding wheels, you will be losing a lot of money and asking yourself a question. Why does the band saw break. The fact is that cheap sharpening discs grind off very quickly and, as a result, cannot ensure uniform metal removal within one working cycle. The sharpening of band saws for metal, which was produced by such discs, can be determined without difficulty. the height of the teeth and the profile change in them when moving from tooth to tooth. By the way, changing the adjustments of the sharpening machine during sharpening leads to the same result. Follow a simple rule: after setting the necessary adjustments, grind one circle of the band saw and only then make adjustments.

Cutters for metal are:

• Carbide
• High-speed (cylindrical, end, disk)
• Cut and slot
• Shaped (with pointed teeth and with recessed teeth)
• End
• End
• Circular saws
• Disk gear cutters
• Worm Gear Cutters

SHARPENING OF CIRCULAR SAWS FOR ALUMINUM, PLASTIC, METAL

Circular saws, depending on their purpose, have different sharpening methods. Using various equipment

• Saw for sawing plastic
• Saw for sawing non-ferrous metals and plastics
• Saw for non-ferrous metals
• Cut-off saws for cutting distance frame HSS
• Scoring saws for cutting PVC bead
• Scoring saws for cutting PVC glazing beads with HW solders
• Saw blade for trimming the end of the impost
• Band saws for metal and wood

For sharpening circular saws used for roughing work, a rough cut, it is allowed to use a semi-automatic special saw sharpening machine. For example such as SSG 600-M-LF SSG 600-A-DC. The SSG-600 series machines are designed for sharpening saw blades and circular milling cutters with a diameter of 100 to 700 mm along the front and back edges of the saw tooth at various longitudinal and transverse angles. One of the advantages of this type of machine is the ability to quickly reinstall the abrasive wheels, depending on the material and the required roughness of the sharpened surface.

• Thus, we get the opportunity to sharpen the following types of teeth:
• – F straight teeth
• – WS alternately beveled
• – TR trapezoidal
• – TR-F tapetzia-straight tooth
• – FZ half-trapezoidal teeth
• – DS triangular teeth. for metal. types A, B, C, AW, BW (only plane sharpening). HZ duplex (only on the back edge). etc.
• For saws used to process chipboard, MDF, plastic, i.e. For materials that are not inaccurate, it is recommended to use an automatic CNC sharpening machine. On such equipment, it is possible to sharpen all of the above types of teeth, but with a much higher quality of the processed surface. In slang. “in the mirror”.
• It is strongly not recommended to sharpen circular saws “manually”.

PROMA PPS-170H 25017000

Differs in excellent performance and ease of operation, gives excellent quality of work on metal. Equipped with an emergency button that turns off a powerful three-phase motor in case of malfunction. It has a simple saw band tension mechanism. It is chosen for serial and small-scale production.

Jet HVBS-712K 414459M

The American type metal band saw is equipped with a reliable and powerful motor that can work for several years without breakdowns. It has quick-clamping and swivel discs, a built-in lubricating-cooling fluid system, which cools the workpiece during cutting to avoid overheating. The machine can work not only horizontally, but also vertically. With the help of a belt drive, one of four belt speeds is selected. Connects to 220V power supply.

Resilience and speed

The durability of the saw band depends on:

• Correct cutting mode.
• Quality of the tape.
• Saw designs.
• Body material and shape.
• Quality of the cutting fluid.

If the machine suddenly vibrates, then you need to change the feed rate in the right direction. The duller the teeth of the belt, the higher the feed should be.

Jet HVBS-712K 414459T

Unlike the above-described machine for metal, this semi-professional one works from a power supply of 380 V. It has a hydraulic feed system and an automatic cut-off switch. Thanks to the powerful motor, this machine can withstand heavy loads and can work for a long time. Quick-clamping and firmly locking vise rotates up to 45 degrees. The kit includes a wire brush for cleaning the workplace from shavings.

Tooth setting

Routing is the alternate bending of the teeth: one to the right, the next in the center, the third to the left, and so on. The stronger their inclination, the higher the required engine power, the wider the cut and the less friction between the saw and the material, which means that the machine will not overheat.

Correct dilution prolongs saw life, produces an even cut, and reduces blade vibration and noise. The band saw blade for metal must be sharpened every time after finishing work or as they become dull. The duller the saw, the lower the quality of work and the higher the required motor power. Blades with teeth are sharpened using special machines with abrasive discs.

Situations in which you need to wire:

• Transition to summer or winter period. In winter, the slope of the inclination of the teeth should be up to 90 degrees, in the summer such a strong slope is undesirable to use.
• If the teeth are damaged.
• For cutting specific metal.

When working with hard metal such as steel, coarse-toothed blades are selected. Soft metal, such as aluminum, is treated with a fine-toothed tape, otherwise the large edges will make it uneven. The pitch of the teeth is variable and rhythmic, the first is suitable for cutting thick pipes, and the second for delicate work.

Recommended cutting data

High speed is fraught with the fact that the machine can make a lot of noise and vibrate, and the web from overload will at best become dull, at worst. it will burst or deform. Therefore, it is necessary to control the feed according to the chip shape:

• Thick, curly, elastic. perfect shavings. Feed rate and speed are right.
• Thick, hard, short or fragile. reduce saw speed and pace. Check coolant.
• Thick, hard, elastic and short. slightly reduce the feed rate, check the correct tooth pitch.
• Thick, hard, elastic and long. increase feed rate slightly, check blade teeth.
• Slim, straight, elastic. increase feed rate.
• Powdery. decrease saw speed and increase feed rate.
• Thin, tightly curled. reduce feed rate and use a coarser tooth pitch.

Top 10 best models

The top of the best models includes both floor and table band saws. If the former are massively used in production, the latter are purchased for households or private workshops. The best metal band saws have a powerful motor and can easily handle hard metal.

Selection and operation of equipment

When choosing a band saw for metal, you need to consider these factors:

• Saw thickness. it should be between 0.9 and 1.1 mm. The smaller the thickness, the lower the feed should be. The standard thickness is 1 mm.
• Saw width. it can be from 14 to 80 mm, most often blades with a width of 31-41 mm are used. Wide band saws handle thicker metal more easily.
• Tooth pitch is the distance between sharp edges of adjacent teeth. The shorter the distance, the more precious the work. Long distance is suitable for working with hard metals, in which case a low speed is used. When regrinding, it is necessary to ensure that the step remains the same.
• Tooth shape. the best shape is considered if the rake angle of the tooth has 10 degrees, the clearance angle and the height of the tooth have little effect on the result.
• Number of teeth. the more teeth, the smoother the cut of thick-walled metal workpieces.
• Notch size. large teeth are chosen for deep cuts, medium ones for curly cuts, small ones for thin metal sheets.

General rules of equipment operation:

• Ensure that the teeth are always sharpened and correctly set.
• Do not work on a faulty machine, otherwise the result will be ruined.
• There must be sufficient light in the work area.
• Follow the shape of the grinding wheel.
• Thanks to individual adjustment, you can achieve impressive results from a conventional machine.
