The disk machine is a rotating disk, on the plane of which an abrasive is fixed (sandpaper). Grinding is carried out by applying the edges or lateral surfaces of the part to the disk, for which approximately in the middle a table or support bar is installed. This design is optimal for grinding straight or convex edges.

The strip type is two drums installed either vertically or horizontally. One of them is driven, the second. stretch. The abrasive is a loop of sandpaper, which is glued along the template.

The loop is installed on both drums and stretches. After starting the engine, she forms a constantly moving abrasive strip. Grinding occurs by pressing the tape to the surface of the part with a special press (“iron”).

It moves left and right, ensuring the pressing of sandpaper to all sections of the processed surface.

The drum machine is used to grind the concave edges. It is a rotating cylinder of a relatively small diameter (6-8 cm), on which an abrasive is installed.

The simplest designs are disk and drummer. The manufacture of a strip machine is much more difficult, but the effectiveness of it is much larger. Such installations allow you to polish the shields and parts of a large area qualitatively, providing high surface quality.

To install a strip machine in the workshop, you need a large area, which must be taken into account when choosing a design.

Features and technical characteristics

The main feature of wood grinding machines is a specific method for adjusting the quality of processing. It occurs by changing the granularity of the abrasive.

Typically, the process begins with sandpaper with large grain, then sequentially reduce its size and complet the procedure with a fine skin with a fine skin.

2-3 shifts are used in total, but there may be more gradual methods.

The second feature is the method of installing an abrasive. If a glued loop is installed on the strip machine, then on disk structures you need to fix the circle from sandpaper to the plane. The optimal way is to use “Velcro”, but the easiest way is to stick abrasive on the adhesive composition or bilateral tape. The second method is simpler, but also more expensive.

Technical characteristics of each machine are somewhat different from each other.

• The width of the tape.
• The value of the working base (the distance between the centers of the drive and stretch drums).
• The speed of the loop.

• The range of movements of the desktop in the vertical and horizontal plane.
• The length of the blank for gluing the loop.

All these parameters depend on the planned performance, the size of the installations, the size of the processed parts. It is necessary to take into account the volume of expected work, the size of the parts, the specifics of processing.

The cleaner the surface should be as a result of grinding, the better the machine should be made. Beats, irregularities and other flaws will cause the appearance of guns that can significantly worsen the quality of processing.

The advantages of grinding machines include:

• Quality and speed of processing.
• High performance.
• The ability to get the surface of the desired roughness.
• The ability to process not only the wood itself, but also the preliminary grinding of the finish layer.
• Highlighting a large amount of dust requiring the organization of a dust system.
• Large quantities of consumables (abrasive) of several sizes.
• Difficulty in manufacture and maintenance (especially this applies to tape installations).

Given the existing shortcomings, before starting the assembly, you need to decide how much the machine is needed. If it is used only occasionally, it is impractical to spend time on manufacturing. you can do with a manual tool.

Consider the methods of assembling grinding machines of different types:

The easiest way to create a disc machine is an electric drill mounted on the table with an installed grinding circle. Another affordable option is the manufacture and installation of a grinding disk on the shaft of a circular saw. At the same time, it is necessary to assemble a device to reduce the speed of rotation (a system of lowering pulleys or an electronic device).

If you need to make a machine “from scratch”, you will have to collect:

• Support site with a stand for an electric motor.
• Stand.

• Disk for installing an abrasive with the possibility of mounting on the engine shaft.

As a rule, plywood discs are made, which are installed on the shaft using a coupling and threaded fastening. This node will have to be ordered from a turner. The height of the table should be such that the fastening of the disk is below its plane.

To assemble such a grinding installation, it is necessary to act in stages:

• Collect the bed. It is two cabinets on which a drive drum with an electric motor and a drive drum with a stretch device will be installed.
• Connect the cabinets with a frame on which the desktop will move (horizontally, perpendicular to the movement of the tape).
• Collect a desktop lifting device to adjust the height when processing large parts.
• Make a device for moving “ironing”.
• Make a protective casing and connect a dust system pipe to it.
• Assemble the electric launch system and stopping the machine (button “Start”, automatic, etc.P.).

The drums for installing an abrasive, tensioning devices to them and the table of lifting/lowering the table are the greatest difficulty. They will have to be partially ordered from the turner, partially collect on the spot. Finding ready.made nodes is unlikely to be possible, since they are very specific and rarely found on common mechanisms.

The device of the machines

Drolling type of drum type belongs to the group of flat.grinding equipment. It is intended for the finishing of all kinds of wooden and wood.containing materials with an abrasive skin of various granularity. The cutting process takes place at high speeds and with a high release of abrasive dust and dust from the cut part of the workpiece.

The use of powerful ventilation systems allows for work on such drum equipment, under relatively comfortable conditions. Structurally, such woodworking equipment is:

• Portal or console type mechanisms;

• On the drum machines of the console type, it is possible to make parts with their turn, which increases the width of the processing;
• The portal design of the drum machines increases its stiffness, allowing you to work with maximum mode indicators without reducing accuracy;

• Starting control of cutting depth;

• with adjustable or stationary supply speed;

The process of grinding wooden materials is to execute the following technological techniques:

• selection of grinding tape of the corresponding grain in accordance with the necessary purity of processing;

• for maximum shooting or peeling. 36 units;
• for the standard process. 80 units;
• finish or final processing. up to 220 units;

• It is possible to wind the tape of various granularity on equipment with paired cutting drums;

The use of an abrasive skin of various grainness, on paired shafts, makes it possible to get the best quality indicators in one pass. Especially when processing a tree with your own hands.

Work principles

The drum grinding machine is quite simple both when performing technological operations and in its maintenance. The order of work on it looks as follows:

• set the necessary cutting parameters;
• With your own hands, season the sandpaper on the cutting drums equipped with its tensioners;
• make calibration of the cutting part;

• Such an operation is necessary for the exact setting of a working drum regarding the supply table;
• Perform this process using 2 calibrated wooden bars located on the width of the supply table under different sides of the drum;
• Having achieved a symmetrical touch of the main shaft of 2 bars, they begin directly to the very technological process of manufacturing the part.

After several passages, in order to maintain the performance and quality of the surface, it is very useful with your own hands to conduct preventive cleaning of the abrasive tape with a special pencil. All similar machines are equipped with such a pencil, including models 10-20. It can be purchased separately.

Homemade drum grinder

Such a drum machine has a specific, very applied purpose. It is not universal and it is quite rare, use in ordinary farms does not contribute to the growth of popularity. The relatively high cost, dimensions and difficulty in preliminary tuning make a similar technique in a poor stepdaughter among the “Bulgarians”, drifts and vibration machines.

Sometimes it makes sense to make a similar table, grinding machine with your own hands, taking as a basis the light series of jet drum equipment. The design of such a home.made, drum mechanism is not complicated:

• The bed and body of the main, cutting part is made of multilayer plywood or good wood with a thickness of 10 to 20 mm;
• It is well suited for these purposes and the engine from the old washing machine, disassembled by yourself;
• It will be difficult to make a working drum, although it will be homemade, the functions will remain the same;

• The grinding drum of a homemade machine is made of a plastic thick-walled pipe of a suitable diameter (like JET model 10-20 plus);
• From a calibrated metal rod (up to 20 mm), the main axis of the cutting node is made;
• They adjust wooden plugs under a plastic pipe and a central axis with their own hands;
• A homemade bearing node will have to be ordered to specialists;
• Having collected the drum node and fixing its parts with each other with fixed elements, glued with a rubber sleeve;

• DIR.handed, from the table, from the side of the feed, is attached to the piano loops;
• On the output side of the grinding machine, an adjustable stubborn screw is installed;

This will look homemade, made with your own hands, a grinding machine for wood considered in an article type. Although, to be honest, it is still dangerous to deal with such homemade.

How to make a drum.type grinding machine yourself?

Grinding various wooden details is the need for everyone who wants to make repairs in his home, or create some element of decor with their own hands.

Of course, you can also polish small parts with ordinary sandpaper, but in order to cope with a large amount of work, the sandpaper should be changed to a grinding machine. It will help to save time significantly and quickly lead the part into the appropriate type. One of these useful devices is the drum grinding machine.

Classification and structure

Type type grinding devices belong to calibration class machines. Such a grinding machine is most often used to work on wood, but they can also process other materials.

Cylindrical grinding circle (drum) allows you to calibrate boards and slats of various lengths and configurations. The workpiece can also be made of different materials: wood-brown slab, veneer, etc. D.

• Cylindrical grinding drum.
• Filefish for serving.
• Dust device.
• Working surface.
• The drum speed converter.
• Engine that drives a grinding cylinder.
• Stannoy for attaching key nodes of the machine.
• A drum height regulator.
• Operator protection device.

The main elements of the structure of the drum machine are listed here. Depending on the specific model of the device and the specifics of its purpose, the configuration may change slightly.

The main models of devices

Drum machines can be purchased in a ready.made form. There are several most popular and common brands for the production of these devices. It makes sense to imagine their individual models.

Jet company. The American company specializes in the production of modern machines of various types, including drum. There are several grinding machines with a cylindrical shape of a working circle in the line of its goods.

• Jet DDS-225. This machine is one of the most powerful devices of this type in the manufacturer line. It is used both in home workshops and in small industries. Characteristic feature. double grinding drum.
• Jet 10-20 Plus. Compact grinding device that allows you to process up to 50 centimeters of surfaces. Great for small home workshops.
• Jet 16-23 Plus. It is considered one of the most universal machines of its type. It is used to process building materials, kitchen devices and even musical instruments. Most often, such a machine is used in small furniture production enterprises.

Corvette 57. Chinese.made machine, which is characterized by quite high build quality and wide functionality. The machine is designed to grind flat surfaces of wooden blanks and wiping parts to the required size. The machine has a rather democratic price. 24 thousand. rubles.

In addition to these machines, there are also good options from German manufacturers. It is worth noting that, depending on the price, German companies also offer appropriate sets of opportunities for their devices. The minimum amount for which you can purchase a grinding machine in the basic configuration-15-16 thousand. rubles.

How to make a grinding machine with your own hands?

If there is no way to lay out a fairly round sum for a worthy version of the drum grinding machine, then you should try to make it on your own. For a person who is well versed in mechanics is not a very difficult task. In addition, you will be able to save significant cash resources.

In order to assemble a drum grinding machine at home, it is necessary to acquire the following parts:

• Grinding drum. The device can be created on the basis of “garbage” building materials in a cylindrical shape. For these purposes, even pieces of wooden bars are often used, which are evenly attached to a special metal axis with glue. In this case, special attention should be paid to the density of the fit of these bars to each other. Also, the drum can be made on the basis of a polyvinyl chloride pipe with a diameter of up to 10 cm, which is put on an iron rod with a diameter of 1.5-2 cm. In length, it should be a little shorter than the rod itself. In the ends of the pipe, insert special plugs with holes for the rod. We recommend fixing the plugs with screws. We extend and fix the rod. We wrap a dense layer of rubber on the pipe, on which sandpaper will be attached.
• Engine. It is best to use a working engine from an old washing machine (like pulleys, belts, etc. D.). The optimal power of the motor should be from 200 to 300 watts. It is desirable that the engine is also asynchronous and single.phase. Revolutions-2000-3000.
• Frame. By design, it should be simple and convenient. It is best for the machine to consist of two side panels, spacers and the table itself. Particular attention should be paid to the strength and stiffness of the desktop, which should not be deformed when the processed workpiece is pressed on the drum. The desktop should consist of the base and the mobile part.

After the main parts of the machine are collected separately, you can start the final assembly of the entire device. First of all, the engine should be attached to the lower part of the machine body at the site of pre.drilled holes. The grinding drum is installed in the upper part of the case and attached to two bearings, which are located on the side walls of the case.

Then we fasten special pulleys on the drum and the motor and pull the drive belt. After all the necessary preparations with electrical wires, we screw the desktop with special bolts that will keep it at the required level. Specialists persistently recommend mounting a protective casing on the machine.

Varieties of machine tools

If we talk about grinding machines in general, their classification is based on two parameters: the scope and the functions performed.

• Round grinding machines. Designed for processing parts with a round section;
• Planning grinding. Their task is to polish flat details. This type of drum machine also includes;
• Intraining. Using such mechanisms, the processing of the internal surfaces of the product is performed. For this purpose, drills are often used;
• Specialized. Designed for processing complex surfaces. threads, grooves, teeth, etc.

Different machines can perform different functions:

2.1 We make a drum machine with our own hands

The drum grinding machine on the unprocessed tree is difficult to make with your own hands, but it is quite possible.

To do this, take a list of the necessary elements and look for suitable material and spare parts.

• Stanin. For these purposes, any stable workbench or table, to which you can fasten other elements of the machine. It is better if the bed is metal. If you have to use a wooden structure, it needs to be strengthened with your own hands efficiently.
• An electric motor with a capacity of 200-300 watts. The speed of the revolution should be 1,500-2000 revolutions per minute. It is better if it is a single.phase asynchronous engine. For these purposes, a mechanism is suitable from the old washing machine (in this case, we take from it and pulleys with a belt), a drill, an angular grinder and t.D.
• Grinding wood drum. This is perhaps the most important and most difficult part of the machine, on which the quality of the work performed will depend. We will talk about how and from what to make a home.made grinding drum with your own hands.
• Racks for the drum. A device that fixes the drum and its height controls can be made of wooden beams. A mechanism that regulates the height can be made with your own hands in two versions. The first option is through holes on the racks through which the drum will be attached. This option is more simple, but it allows you to work only with a fixed adjustment step of about 1 cm. The second option is long screws installed perpendicular to the drum. In this case, clutching the screws, we will be able to raise a grinding device, releasing. lower. In the second option, it is possible to adjust the height with an accuracy of a millimeter.

We will not make a conveyor tape with our own hands. This is possible, but this is not necessary. Feed on homemade machines, as a rule, is carried out manually. To the menu

2.2 We make a drum

Before starting the manufacture of the drum itself, you need to clearly understand what functions our machine will perform. The fact is that the smaller the size of the cylinder, the easier and faster it will rotate the engine from the drill.

For the manufacture of a grinding drum, we need a piece of anything that has a cylindrical shape, the required length and diameter. It can be a wooden beam with a round section, PVC pipe, metal pipe and much more.

Homemade workers’ drum

We will consider the PVC pipe as a material for the manufacture of a drum with our own hands.

• We take the plastic pipe required in size. We also need a metal pin, acting as an axis, wooden or plastic plugs that match the diameter with the inner diameter of the pipe, screws, rubber, glue.
• We take the plugs and make holes in them, corresponding to the diameter of the thickness of the rod.
• Holes in the plugs should be strictly in the center. The slightest eccentricity of the drum will lead to improper operation of the machine.
• We tightly put the plugs in the pipe and fix it using screws.
• Insert the pin into the holes in the plugs. The axis should protrude from the cylinder 2-3 cm on each side. It will be the role of attachment to the adjusting racks.
• We glue the rubber on the drum. It will be easier to fix the grinding tape to it.

2.3 We collect the machine

• Install the racks on the bed.
• Attach the drum to them so that the height of its rise can be adjusted.
• Connect the engine to the drum using a belt or chain drive.
• You can start work.

DIY home.made grinding machine

During the manufacture of wooden structures, it is necessary to clean their surfaces. Manual labor will take a lot of time and will not be productive. Factory grinding centers have a high cost. Therefore, in some cases it is more advisable to make a machine with your own hands.

Production should start by studying the design features of this type of equipment. Drolling type grinding machine is designed for processing wooden surfaces, equalizing and removing the burr.

The device belongs to the type of flat.grinding machines for wood, which perform the function of calibration. There are many models and types of equipment. But the main task of making the unit with your own hands is to choose the optimal design. The best option is a detailed familiarization with factory analogues and drawing up a manufacturing scheme based on the data obtained.

Structurally, the machine should consist of the following components:

• frame. The main parts of the equipment are attached to it;
• power unit. Most often, an asynchronous electric motor is installed for this;
• Grinding drum. It is important to choose the right diameter, the way of removing the chips. With your own hands, you can make the basis on which the sandpaper is installed. Or order a cylindrical head with a cutting edge from a professional turner. It all depends on the type of work;
• device for changing the frequency of engine shaft;
• Desktop. It will be located on it. Experts recommend this component to make this component in the manufacture of a machine from fiberglass;

Additionally, in a drum.grinding equipment, it is possible to provide a mechanism for removing dust and chips from the processing zone. It is also recommended to make a desktop with a variable height relative to the working drum. This will make part of the end of the wooden workpiece.

If you need grinding the outer or inner plane of the board. the drum should be located horizontally. In this case, it is possible to adjust it in height.

Cut the main parts of the frame

I used to cut out parts of my project one at a time at a time, immediately checked whether it was suitable for others, and made another incision. But it takes too much time. So this time I tried to cut everything in one sitting. This means that I need to measure everything very accurately and cut off. But is it really possible to do this on a lobby, like me? Yes, later I needed to cut only a few pieces. It happened much faster. Having cut out all the parts from plywood 12 mm thick, I placed the main parts of the frame and made several more cuts.

Glue the details and make a hole for the vacuum cleaner

We glue the details one after another. It takes a lot of time, but it is easy to achieve perfect results. Having glued only one side, I made a hole for the vacuumber. His design is simple. Since the external diameter of my vacuum connector is 35 mm, there will be three parts of plywood (including a hole on the side) with holes of 35 mm. The last hole will be a diameter of 25 mm, as this is the internal diameter of the connector. He will also act as a stopping unit for maximum depth.

Making a machine for grinding with your own hands

The desire to independently make wood structures always pushes to equip your workshop with grinding and sawing machines. They are produced in a large assortment by modern manufacturers. Such machines have excellent characteristics, as well as a high degree of reliability. The most important and significant drawback is the greater cost. For this reason, many masters try to collect grinding machines from what is at hand.

The most experienced are trying not to limit themselves to a machine that performs only one function, and collect a universal device that can cut wooden blanks, polish and polish, remove the old coating and prepare surfaces for updating. This is real due to the fact that the basis of each machine is a bed that is fixed by an electric engine, a driven and drive drum, a set of additional equipment (mills, rila, grinding circles, etc.

Calculation of the power of the machine

Before starting the assembly of the machine, you need to calculate the power.

To do everything right, you need to determine the following parameters:

• Power consumed by an electric engine.
• The speed of rotation of the motor.
• The area of ​​contact of the surface of the part and the moving abrasive tape.
• Grinding coefficient.
• The friction indicator of the back of the applied tape with the surface of the twisting drums.

Based on data on such parameters, you can determine the power of the future device.

How to make a grinding ribbon machine

To make a grinding machine with your own hands, you will need to take into account many points. The basis of the machine will be a powerful base that can withstand the weight of the equipment and perform the function of damping the emerging vibration. The frame of the bed should be stuck with welding. At the top, attach the plate, and in the role of such a stove you can use a wood-brake plate, which is not less than 2 in a thickness.2 cm. Next, attach an electric engine to the bed, and its power should not be lower than calculated earlier. The number of revolutions of the motor should be at least 15,000 revolutions in 1 minute. Anchor attach the gearbox to transmit rotation to the leading drum. The desired diameter will depend on the speed of rotation of the motor, and this will determine the speed of the tape during friction at the time of friction on the surface of the parts.

From what to make the base (bed)

The frame, to which all other machine elements are attached, is a stable, good bed. It should be with a large margin of safety, and also have an excellent mass.body characteristics. It is made of sheet steel, with a thickness no more than 0.5 cm. The most acceptable are the dimensions of a dock made by yourself about 50182 cm. For the founding of this size, the optimal size of the working site will be 18161 cm. For the convenience of future work, markings should be made on the work site, and for fastening, you should make three holes, and then use three bolts to attach everything to the bed.

The selection and installation of the engine for the machine

The calculations and the experience of using this kind of device shows that an electric engine must have a power of at least 2.5 kW, but no less. The speed of rotation of the shaft should be from 1,500 revolutions in 1 minute or more. The speed of the abrasive tape will depend on the speed of the electric motor rotation. This greatly affects what the assembly quality will be. In turn, the speed of movement of the tape will affect the diameter of both drums. In the role of a finished device, you can use an engine, which is usually used for washing machines. You can also choose an electric engine from another economic unit, for example, a very powerful pump or other device that is suitable in terms of revolutions and power.

Leading and leading drum

The leading drum must be fixed tightly on the pulley of the electric engine, and the driven drum will be fixed on a separate axis. In order to ensure free rotation between the drum and the shaft, the bearings should be attached.

Tape for grinding

In the manufacture of a mini.grinding machine, you should take care of the abrasive tape for grinding in advance. Usually they have a fabric base, and a calico or other, but similar fabric is used as a basis. Abrasive crumbs are applied on the surface of matter on one side with a special glue, and depending on the size of the crumb grain, it will be divided into large, medium, small and zero.

Types of grinding machines

The next step is the choice of the design of the wood machine. The main parameter is the shape of the wooden workpiece and the degree of processing. The drum.type homemade equipment is intended for the formation of even and smooth surfaces with a small area.

For factory production lines, special processing centers are needed. They have complex functionality, can simultaneously perform several operations. However, their main drawback is the high cost. Therefore, as home equipment, it is impractical to consider them.

The following types of processing centers exist:

• Planning grinding. Processing is performed in one plane. Can be used as an example for independent manufacture;
• Round grinding. Designed for processing cylindrical surfaces. For this, several nozzles with various diameters are provided in the configuration;
• planetary. With their help, the formation of a flat plane on products with a large area occurs.

To equip a small home workshop, they most often choose flat.grinding models. They are characterized by a simple design, accessibility of components and relatively quick manufacturing.

In addition to aligning using drum grinding machines, you can remove a layer of paint or varnish. They are used to restore old furniture or wooden interior details with your own hands.

Self.manufacture of a grinding machine

With your own hands the simplest model of the machine is a drill that is mounted on the bed. Grinding cylinders are pulled out of wood and sandpaper is attached to their surface with the required grain indicator.

But such a design has a small functionality. For processing medium volumes, it is recommended to make wood equipment according to another principle. First of all, it is necessary to choose the right power unit correctly. Most often used an electric motor with a capacity of up to 2 kW and a speed of up to 1500 rpm. Asynchronous models meet these requirements, which can be taken from old household appliances. a washing machine or vacuum cleaner.

The procedure for making a home.made machine.

• Frame. It should be stable enough. Therefore, it is made of sheet steel with a thickness of 1.5 mm or more. As an alternative, you can consider an plexiglass 10 mm thick.
• The engine is installed in such a way that the shaft is in the vertical plane.
• Drum for processing. If it is planned to perform only grinding work, an abrasive tape is installed on it. For deeper processing, you need to make a steel cone with a cutting edge.
• Desktop. It is located in the upper part of the scheme. It is recommended to make it adjustable relative to the motionless cylinder.
• Control block. DIY structures rarely provide for the possibility of adjusting the speed of engine rotation. Therefore, the block will consist of the buttons of turning on and off the unit.

During the operation of the equipment, shavings and wooden dust will inevitably form. The structure can be improved by installing a household vacuum cleaner pipe in the processing zone.

In the video, you can familiarize yourself with the example of the design made by yourself:

Drum drum grinding machines, with your own hands. turner

In this review, the master shows how, using simple and affordable materials, make a drum grinding machine with your own hands.

For the manufacture of a grinder, a 20 mm thick plywood will be required, as well as some other materials.

First of all, the master cuts off two pieces of plywood. Having put a gap between them, the author connects them with the help of four door loops.

It is necessary to attach wooden bars to the lower sheet of plywood, which serve as limiters for the top sheet and ramps for shaft.

The main stages of work

At the next stage, two guides must be screwed to the lower sheet of plywood.

Between them, the author sets a movable support platform, with which you can adjust the angle of inclination of the upper sheet.

Cabinet bearings are attached to the side racks, into which a wooden shaft is inserted.

Then it will be necessary to install an electric motor (for him the master made a separate platform that is attached to the base).

At the last stage of work, it will only remain to wrap a grinding tape of suitable grainness onto the shaft.

The advantage of this design is that you can grind large furniture shields.

The device of the machines

Drolling type of drum type belongs to the group of flat.grinding equipment. It is intended for the finishing of all kinds of wooden and wood.containing materials with an abrasive skin of various granularity. The cutting process takes place at high speeds and with a high release of abrasive dust and dust from the cut part of the workpiece.

The use of powerful ventilation systems allows for work on such drum equipment, under relatively comfortable conditions. Structurally, such woodworking equipment is:

• Portal or console type mechanisms;

• On the drum machines of the console type, it is possible to make parts with their turn, which increases the width of the processing;
• The portal design of the drum machines increases its stiffness, allowing you to work with maximum mode indicators without reducing accuracy;

• Starting control of cutting depth;

• with adjustable or stationary supply speed;

The process of grinding wooden materials is to execute the following technological techniques:

• selection of grinding tape of the corresponding grain in accordance with the necessary purity of processing;

• for maximum shooting or peeling. 36 units;
• for the standard process. 80 units;
• finish or final processing. up to 220 units;

• It is possible to wind the tape of various granularity on equipment with paired cutting drums;

The use of an abrasive skin of various grainness, on paired shafts, makes it possible to get the best quality indicators in one pass. Especially when processing a tree with your own hands.

Work principles

The drum grinding machine is quite simple both when performing technological operations and in its maintenance. The order of work on it looks as follows:

• set the necessary cutting parameters;
• With your own hands, season the sandpaper on the cutting drums equipped with its tensioners;
• make calibration of the cutting part;

• Such an operation is necessary for the exact setting of a working drum regarding the supply table;
• Perform this process using 2 calibrated wooden bars located on the width of the supply table under different sides of the drum;
• Having achieved a symmetrical touch of the main shaft of 2 bars, they begin directly to the very technological process of manufacturing the part.

After several passages, in order to maintain the performance and quality of the surface, it is very useful with your own hands to conduct preventive cleaning of the abrasive tape with a special pencil. All similar machines are equipped with such a pencil, including models 10-20. It can be purchased separately.

Homemade drum grinder

Such a drum machine has a specific, very applied purpose. It is not universal and it is quite rare, use in ordinary farms does not contribute to the growth of popularity. The relatively high cost, dimensions and difficulty in preliminary tuning make a similar technique in a poor stepdaughter among the “Bulgarians”, drifts and vibration machines.

Sometimes it makes sense to make a similar table, grinding machine with your own hands, taking as a basis the light series of jet drum equipment. The design of such a home.made, drum mechanism is not complicated:

• The bed and body of the main, cutting part is made of multilayer plywood or good wood with a thickness of 10 to 20 mm;
• It is well suited for these purposes and the engine from the old washing machine, disassembled by yourself;
• It will be difficult to make a working drum, although it will be homemade, the functions will remain the same;

• The grinding drum of a homemade machine is made of a plastic thick-walled pipe of a suitable diameter (like JET model 10-20 plus);
• From a calibrated metal rod (up to 20 mm), the main axis of the cutting node is made;
• They adjust wooden plugs under a plastic pipe and a central axis with their own hands;
• A homemade bearing node will have to be ordered to specialists;
• Having collected the drum node and fixing its parts with each other with fixed elements, glued with a rubber sleeve;

The disk machine is a rotating disk, on the plane of which an abrasive is fixed (sandpaper). Grinding is carried out by applying the edges or lateral surfaces of the part to the disk, for which approximately in the middle a table or support bar is installed. This design is optimal for grinding straight or convex edges.

The strip type is two drums installed either vertically or horizontally. One of them is driven, the second. stretch. The abrasive is a loop of sandpaper, which is glued along the template.

The loop is installed on both drums and stretches. After starting the engine, she forms a constantly moving abrasive strip. Grinding occurs by pressing the tape to the surface of the part with a special press (“iron”).

It moves left and right, ensuring the pressing of sandpaper to all sections of the processed surface.

The drum machine is used to grind the concave edges. It is a rotating cylinder of a relatively small diameter (6-8 cm), on which an abrasive is installed.

The simplest designs are disk and drummer. The manufacture of a strip machine is much more difficult, but the effectiveness of it is much larger. Such installations allow you to polish the shields and parts of a large area qualitatively, providing high surface quality.

To install a strip machine in the workshop, you need a large area, which must be taken into account when choosing a design.

Features and technical characteristics

The main feature of wood grinding machines is a specific method for adjusting the quality of processing. It occurs by changing the granularity of the abrasive.

Typically, the process begins with sandpaper with large grain, then sequentially reduce its size and complet the procedure with a fine skin with a fine skin.

2-3 shifts are used in total, but there may be more gradual methods.

The second feature is the method of installing an abrasive. If a glued loop is installed on the strip machine, then on disk structures you need to fix the circle from sandpaper to the plane. The optimal way is to use “Velcro”, but the easiest way is to stick abrasive on the adhesive composition or bilateral tape. The second method is simpler, but also more expensive.

Technical characteristics of each machine are somewhat different from each other.

• The width of the tape.
• The value of the working base (the distance between the centers of the drive and stretch drums).
• The speed of the loop.

• The range of movements of the desktop in the vertical and horizontal plane.
• The length of the blank for gluing the loop.

All these parameters depend on the planned performance, the size of the installations, the size of the processed parts. It is necessary to take into account the volume of expected work, the size of the parts, the specifics of processing.

The cleaner the surface should be as a result of grinding, the better the machine should be made. Beats, irregularities and other flaws will cause the appearance of guns that can significantly worsen the quality of processing.

The advantages of grinding machines include:

• Quality and speed of processing.
• High performance.
• The ability to get the surface of the desired roughness.
• The ability to process not only the wood itself, but also the preliminary grinding of the finish layer.
• Highlighting a large amount of dust requiring the organization of a dust system.
• Large quantities of consumables (abrasive) of several sizes.
• Difficulty in manufacture and maintenance (especially this applies to tape installations).

Given the existing shortcomings, before starting the assembly, you need to decide how much the machine is needed. If it is used only occasionally, it is impractical to spend time on manufacturing. you can do with a manual tool.

Consider the methods of assembling grinding machines of different types:

The easiest way to create a disc machine is an electric drill mounted on the table with an installed grinding circle. Another affordable option is the manufacture and installation of a grinding disk on the shaft of a circular saw. At the same time, it is necessary to assemble a device to reduce the speed of rotation (a system of lowering pulleys or an electronic device).

If you need to make a machine “from scratch”, you will have to collect:

• Support site with a stand for an electric motor.
• Stand.

• Disk for installing an abrasive with the possibility of mounting on the engine shaft.

As a rule, plywood discs are made, which are installed on the shaft using a coupling and threaded fastening. This node will have to be ordered from a turner. The height of the table should be such that the fastening of the disk is below its plane.

To assemble such a grinding installation, it is necessary to act in stages:

• Collect the bed. It is two cabinets on which a drive drum with an electric motor and a drive drum with a stretch device will be installed.
• Connect the cabinets with a frame on which the desktop will move (horizontally, perpendicular to the movement of the tape).
• Collect a desktop lifting device to adjust the height when processing large parts.
• Make a device for moving “ironing”.
• Make a protective casing and connect a dust system pipe to it.
• Assemble the electric launch system and stopping the machine (button “Start”, automatic, etc.P.).

The drums for installing an abrasive, tensioning devices to them and the table of lifting/lowering the table are the greatest difficulty. They will have to be partially ordered from the turner, partially collect on the spot. Finding ready.made nodes is unlikely to be possible, since they are very specific and rarely found on common mechanisms.

Wood grinding machine: how to make it with your own hands?

Grinding wood is a mandatory procedure preceding finishing. To perform work, special machines are used, acting on different principle and polishing material in different directions. However, the price of such devices is quite large. It is not always advisable to purchase equipment that will be used from case to case to case to case. It is more correct to make a wood grinding machine with your own hands, which will cost much cheaper and will allow you to get a completely effective device.

There are three main designs of wood grinding machines:

The disk machine is a rotating disk, on the plane of which an abrasive is fixed (sandpaper).
