If you need to achieve the most even and smooth plane, you can not do without. With its help, the work, if not done by itself, then, in any case, will require much less time and effort. One thing remains - to understand how to choose a grinder from a great variety of types.

The basic principle is this: the design determines the scope. Consider different types grinders, starting with the most popular. We hope this review will help you understand which sander is best for your application.

Designed for roughing large surfaces or removing rust or paint. Distinctive feature- high level of productivity.

Provides good machining quality for both rough and fine grinding. Equipment - abrasive sheets with Velcro or simple sandpaper, which is attached to the clamps.

They differ from the previous type in the shape of the sole - in these grinders, it is deltoid (ironing). Ideal for advanced tasks such as sanding stairs, furniture, skirting boards.

They are used for finishing grinding, including complex and curved surfaces. The speed of work is also impressive.

LBM is more often used for cutting. However, the grinder will cope with grinding with a bang. She is able to process materials such as concrete, stone, ceramics or metal. Don't expect very high surface quality.

Tool for professionals

Above are the 5 types of grinders that a DIYer may need. Next, let's look at more specialized varieties.

A tool for decorative surface treatment. Helps to accentuate the texture of the wood. Also used for cleaning surfaces from rust or paint. The name is given by the type of equipment - hard brushes made of metal, nylon or polymers.

The main purpose is to clean weld seams, remove burrs and rust. Designed for intensive work.

With their help, they level hard surfaces of materials such as concrete, granite, stone. Dust extraction is required. Wet sanding is possible on some models.

Top 3 most popular grinders

It is quite difficult to choose which grinder from the presented ones is better. We have compiled a short rating of the best models (according to users):

• MAKITA BO3711 - surface grinder. Recommended for finishing.
• HAMMER LSM810 - belt sander. It stands out against the background of other models with its power (810 W).
• HAMMER OSM430 is an eccentric sander. Suitable for working with a variety of materials.

Leading manufacturers

Before choosing a grinder, we recommend that you pay attention to the brand.

The wood sander is an indispensable tool when carrying out finishing works... Thanks to its use, the process of polishing and grinding wooden surfaces is significantly accelerated. The unit itself is convenient and compact, which makes it possible not only quickly, but also to level the walls, floor, furniture and other wooden surfaces with high quality.

At the moment, there are four types of grinders, which differ in terms of application, design, operating principle and other criteria. The following types of grinding machines can be used for carpentry and joinery, as well as repair and construction works:

1. LShM - belt grinders;
2. VShM - vibration grinders;
3. OShM - orbital sander;
4. Delta sander.

The choice of the machine is directly influenced by the scale of the upcoming work (for home or professional use).

Belt sander

The belt sander is ideal for professional use.

The belt-type design includes two rollers (leading and driven), which, in the course of their movement, actuate the belt attached to the sole of the tool. Depending on its pricing policy, this tape can be made of various materials.

An important technical characteristics all grinders have their operating speed, which depends directly on the power of a particular model. For LSM, this value can be in the range from 500 W to 1200 W at a speed of 75-500 m per minute. Most of the manufacturing firms equip their products with a special regulator to control the belt speed.

The dimensions and other features of this tape also depend on the capabilities of the tool. Therefore, in the selection process, the following factors must be taken into account:

1. Lenght and width. The more their values, the more functional the model is. However, with the growth of these indicators, the mass of the machine, as well as its parameters, increases.
2. Granularity. Usually, professionals recommend keeping in stock several of their varieties, which are designed for fine and rough grinding. Thus, you can count on the expected result of the work.

In general, LShM are industrial units with a sufficiently high power. With their help, it is possible to process large areas in a short period of time and, as a result, obtain an ideal smooth surface... It will be difficult for a person without experience to operate the grinder, which can lead to damage wooden surface.

The belt-type machines are ideal for rough and quick processing of wood, metal and plastic surfaces.

Vibratory sander

The most popular type among all grinders.

In terms of the frequency of processing wooden surfaces, the vibration machine is slightly inferior to the belt type. With its help, the final (finishing) stage of grinding wooden, plastic, metal or stone flat surfaces takes place.

The main part of the machine is a plate that makes frequent reciprocating movements. The very same shaft rotation is translated into translational movements of the platform due to the vertically located motor.

What to look for when choosing this tool:

• Outsole quality. The sander should have a perfectly flat, high-quality sole with a clear geometry. Cheaper options include a plastic or steel platform, while more expensive options include magnesium and aluminum alloys.
• The material from which the pad is made. A porous polymer pad is considered best, while rubber works worse with a plane.

The vibratory sander processes any surface with high quality. This is the best option for processing hard-to-reach places.

Orbital sander

The Bosch GEX 125–150 AVE model has 400 W of power, which can easily stretch the sole up to 15 square meters. cm.

The orbital or eccentric machine features a round sole, while the sanding element itself is attached with a special Velcro. The unit includes a counterweight and an eccentric that drive the sole in multiple directions.

The product can work in two ways:

1. By orbiting;
2. By rotating along the axis.

Axial movement in most models occurs by inertia, less often - forcibly. As a result of its complex movement and high speed of the machine, a high quality surface is obtained without any single flaws. Dust is discharged to the outside through special holes on the grinding wheel, as well as on the sole itself. Containers or a vacuum cleaner are used to collect it.

Features of the models:

• The power of the grinder can vary between 200-900 watts. The higher the value, the more productive the tool will be.

• The speed of the forward motion. Adjustable grinders can have this indicator in the range of 4000-14000 rpm, without adjustment - up to 12000 rpm.
• Sole type. If delicate sanding is required, then you should not choose a large sole, which also has a dead zone and an amplitude of up to 7 mm. For convex surfaces, it is advisable to use an elastic pad.

The compact outsole is capable of handling even hard-to-reach surfaces.

• Plate material. The best choice is a metal plate, which has high strength and reliability, conducts heat well, and is also particularly stable.

The orbital type is designed to carry out the polishing and grinding process at a high level.

Delta sander

This type of grinder is designed for the processing of surfaces not only made of wood, but also metal, plastic and stone. According to principle

Compact and versatile delta sander.

work they are similar to vibration models. Their feature is the shape of the plate, which makes it possible to perform high-quality grinding work even in hard-to-reach places.

The movements of the sole are carried out at high speed and have a reciprocating appearance. For both home and professional use, it is advisable to choose a powerful model with the ability to regulate the speed of its operation. Thus, it becomes possible to work with several types of surfaces.

A wide range of modern products allows you to choose models with special holes for removing dust, the ability to install additional attachments, rotating soles and other features of work.

The delta sander is designed for polishing and cleaning any surface, even in hard-to-reach places.

• Important details. Before choosing a particular model, it is worth checking all moving parts for backlash, as well as the degree of accuracy of fitting the components of the case.
• Noise and vibration levels. To evaluate these indicators, it is worth including the selected model directly in the store. This is the only way to evaluate the performance of its work.
• The cost of components. It is worth clarifying in advance what the cost will be possible repair, consumables and accessories that may be needed in the process.

Do not rush into choosing a sander. Only by carefully weighing all the pros and cons, you can purchase a quality tool that allows you to produce renovation work at a high level.

This article is for anyone who works with wood and wants to make sanding easier. A wood sander is perfect for this, which model should I choose?

There are several types of wood finishing tools on the market: belt sanders, eccentric, orbital. So, which grinder to choose, which type of device is best suited for specific purposes?

Before finding the answer to this question, you need to understand how different models differ and compare their functions with our needs.

How to choose a wood sander - tips

Sanding wood is a laborious process that can be made much easier using the right tools. For wood processing, belt sanders, oscillating or eccentric sanders, as well as deltoids, are best suited.

The correct choice of the device depends on the type of work being performed and on the characteristics of the workpieces: shape, size, grinding of corners and hard-to-reach areas, type of coating, etc.

For individual works different tools are better suited, namely:

• a belt sander is best for sanding large and flat surfaces;
• the eccentric sander allows you to conveniently handle convex and concave small wooden surfaces;
• the oscillating model has a similar application, with the possibility of processing corners thanks to the rectangular sole;
• The delta sander is ideal for complex surfaces not available to most sanders, while its small foot area is generally recommended for small wood surfaces.

Wood belt sander - how to choose?

Description and purpose of the model

If the surface we are dealing with is large and relatively flat, then it is better to choose a belt sander. It is designed for processing solid wood, varnished boards and veneered panels.

Belt sanders are characterized by the highest efficiency, they are most often used in workshops and rarely for household work.

Due to their high productivity, belt grinders can process large areas in a short amount of time with excellent results. The treated surface is smooth and uniform. In addition, since belt sanders are primarily used for linear motion, they are ideal for sanding along wood grain.

The disadvantage of belt sanders is the design of the base, which does not allow access to hard-to-reach corners. The edge of the tape is not at the same time the edge of the sole, so surfaces such as near a wall are inaccessible for this appliance. In this case, a deltoid model is needed.

Which belt sander should you choose?

To choose the right belt sander, you should pay attention to the following parameters:

• Working part speed - the higher the speed, the faster and more precisely the surface is sanded. Depending on the model, the speed can vary from 200 to 420 rpm.
• Belt size - this parameter affects the speed and accuracy of grinding. But be careful! The larger the size, the faster the grinding occurs, but at the same time, its accuracy decreases.
• Power - The higher the power, the better the tool will handle hard and more difficult surfaces such as hard hardwood (oak). Thanks to the high power, the tool can work longer without overheating.

If we need a wood belt sander, how to choose the right power? Belt sanders with motor power up to 1000 W are mainly designed for light jobs, while those with motor power over 1400 W will perform well under short-term but heavy loads.

Model overview

Below are the models of grinders recommended by specialists. Distinctive characteristics are highlighted for each model.

1. Grinder Graphite 59G394. The small diameter of the front roller (16 mm) and the additional handle with an adjustable angle make it easy to sand in hard-to-reach places.

2. The Makita 9920 is a powerful and professional belt sander with electronic speed control for optimum performance. Thanks to the automatic lateral adjustment of the belt, the surface can be sanded to the very edge.

Purpose of the tool

The eccentric sander is the most versatile tool for sanding convex and concave small wood surfaces and many other materials.

This model is used in the following cases:

Ideal for sanding wood;

Suitable for grinding metal surfaces;

Also useful for polishing, thanks to the possibility of installing a polishing disc;

Can be used to clean old paintwork.

An eccentric or orbital sander for wood is especially recommended for processing and updating furniture: dressers, tables. Orbital sander has a plate that rotates as well as oscillates. As a result, such devices work faster than oscillating sanders. However, this tool also has disadvantages, eccentric sanders are characterized by a round sole, which does not allow processing corners.

The diameter of the working part is usually 125 or 150 mm. Of course, the larger the work surface, the higher the productivity. However, the working surface of an eccentric sander is smaller than that of an oscillating one. This has its pros and cons: the advantage of a smaller outsole is that it is easier to work with in tight spaces, the cons is less performance on large surfaces.

How to choose an eccentric wood sander?

To figure out which orbital sander to choose, you need to analyze the following parameters:

• Eccentricity is a parameter that has a significant impact on tool performance and refers to the deviation of movement of the sole from the pivot point. The higher the value, the more precisely a tool works.
• Disc diameter - large diameters allow you to quickly process large surfaces. Small diameters, in turn, are better suited for working in hard-to-reach places.
• The number of revolutions per unit of time - the more the number of revolutions, the more accurately the tool works (as in the case of an oscillating machine).

Model overview

1. The Bosch PEX 400AE eccentric sander provides high-quality sanding, high efficiency and optimum polishing performance. The Paper Assistant function makes sanding paper easy to pull. Supplied in a suitcase with a set of sandpaper. An integrated suction unit transports the crushed dust directly to a container that can be easily emptied.
   
2. The Bosch random orbit sander 400W GEX 125-150 AVE is designed for professional use. Extremely versatile thanks to the choice of a grinding disc with a diameter of 150 or 125 mm. Supplied in a suitcase with a set of sanding pads
   

   Oscillating sander - advantages and disadvantages

   Main characteristics

   The oscillating sander is used for sanding flat and even surfaces. It is ideal for woodworking such as furniture, countertops and doors.

   In contrast to the eccentric model, the oscillating sander is equipped with a rectangular sole, thanks to which you can sand corners. More powerful are the larger models, the sole of which has a rectangular or square shape.
   

   How to choose an oscillating sander?

   Before buying, you need to pay attention to:

   Amount of oscillation - the higher this value, the better the tool performs. Usually referred to as the number of vibrations per minute.

   The size of the sole - the larger it is, the faster the surface will be processed. However, when working on small surfaces, it is better to choose an oscillating sander with a smaller sole, as this will allow you to more accurately machine hard-to-reach areas.

   
   

   How to choose a delta sander?

   Model Description

   The main difference between deltoid sanders and oscillating ones is the sole. In shape, it resembles the letter delta (hence the name of this type of instrument). This model is ideal for sanding in corners and other places that are difficult to access for oscillating, eccentric and especially belt sanders.
   

   Due to the small size of the sole, they are designed for sanding small surfaces. In addition, a spatula-shaped sole can be purchased for the deltoid model. Thanks to it, delta sanders will be useful when cleaning old paints and varnishes, especially from chairs.

   What to look for when choosing a delta sander?

   When choosing a deltoid model, one should analyze such a parameter as the amplitude of oscillations (oscillation) - usually indicated in millimeters and ranges from 1 to 2 mm. The higher the value, the more the sole deflects, and the tool works more efficiently.

   Model overview

   1.The DeWalt D26430 is designed for professionals. It guarantees high efficiency when sanding and polishing in corners and edges, in hard-to-reach places and on small surfaces. The design provides smooth maneuvering and precise grinding for more precise work. The dust collection system ensures convenient operation.
   

   2. The Bosch PSM 18 Li is primarily intended for home use. It has a bifurcated sanding pad and a pivoting Delta tip that allows optimal use of the sanding paper. An integrated suction unit transports dust directly to the microfilter container for a dust-free operation. The cordless sander offers virtually unlimited performance - no inconvenience with too short cables.
   

   How to choose a sander for your home - summing up

   1. Belt sander extremely efficient and works very quickly on large surfaces. For example, this appliance can quickly remove a very thick layer of paint from wood surfaces. The design is characterized by a very high power rating. The machine is extremely easy to use and safe.
   2. Orbital sander Is a good quality tool used for sanding flat and rounded surfaces. These models have the highest accuracy. However, the outsole does not reach hard-to-reach places such as corners. The machine has a circular disc that oscillates and rotates simultaneously, depending on the pressure. It is also easy to use, but requires a little more attention than oscillation. This instrument is held with both hands. Thanks to the combination of the two movements of the plate, the model is very efficient, fast, productive and, if used skillfully, leaves no visible sanding marks.
   3. Oscillating sander used for large flat surfaces. If we've never sanded before, it's best to start with this device. It perfectly smoothes the surface, while its work depends on the thickness of the sandpaper. The machine is very easy to use and safe. It doesn't require special attention.
   4. Deltoid machine- small triangular outsole makes it easier to work on surfaces inaccessible to large sanders. However, the small footprint also makes the model ineffective for large surfaces.

In this article we will talk about wood sanders, application features, types and consider the best models. Every owner needs such an apparatus to complete finishing work.

With the help of a sander, you can quickly do such processes as polishing and sanding wood, you can work with floors, walls, furniture and various decorative elements.

Such a tool is useful to anyone when performing various operations, because it has many functions. In general, sanding is hard and boring work, but a sander will help you cope with this difficult task quickly and with pleasure.

Wood grinder

The wood sander is an essential and multifunctional tool. It can be used for repair, construction, restoration of all kinds of wooden products.

The grinder makes it possible to speed up the process of sanding or polishing wood surfaces, whether it be walls or floors, furniture or other decorative elements, by several times.

The advantages of grinders:
• Convenience. When working with a sander, fatigue does not occur, and hands do not go numb. This is possible thanks to the ergonomic handles of the unit.
• Compactness. Most of the machines are small in size, which allows the unit to be lightweight with great functions.
• Versatility. With a sander, you can polish or grind both flat surfaces and, for example, convex ones.
• Accuracy. This tool allows you to smoothly and accurately level the wood surface.
• Speed ​​of execution. This tool is a great time saver compared to hand sanding.
• A flawless result. All elements, from beams to small decorative elements, will have a beautiful smoothly sanded polished surface.

Before choosing a tool, you need to understand its basic characteristics.

Grinder parameters:
1. Power. The performance of the grinder depends on this parameter. The power of this tool ranges from 600 to 2500 watts. The more power of the unit, the higher its quality indicators. They weigh more and the cost is much more expensive.
2. Working surface area. This value affects the speed at which work is done. The larger the area of ​​the working surface, the faster it will be possible to grind the desired plane. Belt options have a smaller working surface, and vibrating ones have a larger one.
3. Disc diameter. The area that can be processed at one time depends on the diameter. This parameter also affects the time of finishing work.
4. Additional equipment. Different models can be equipped with additional auxiliary elements.
5. Additional handle. The handle helps to evenly distribute the load and reduce vibration. Basically there are two-position, less often three-position.
6. Dust collector. Collects dust that forms during the operation of the mechanism. It can be either built into the unit itself, or be a removable element on the side. There are removable and permanent dust collector options.
7. Stabilizer of turns. It can be used to control the speed. The stabilizer allows optimal use of the grinding machine's performance.
8. Speed ​​controller. With its help, you can control and adjust the speed required for work.
9. Case. Convenient way to store and transport the tool.
10. Battery. For autonomous use of the grinder, some models are equipped with a removable battery.

Grinding machines come in a variety of designs and operating principles. These factors depend on their purpose.

LSHM is used for the initial processing of wood materials, for example, for quick removal of the first layer when grinding or removing outdated paint. Also, this type of grinder is suitable for precise fitting of furniture parts.

LShM works on the principle of a plane: a circle-shaped belt rotates on rollers and, when pressed, grinds the wooden surface. The layer that is removed from the surface depends on the grain size of the tape. The higher the grain number, the neater and thinner the layer being removed.

This type of grinder has a number of advantages:
• processing of rough surfaces, it can be used even for non-planed boards, but immediately proceed to sanding;
• can be successfully used in hard-to-reach places such as corners or curls in decorative items
• precise fit or trimming of parts along the marking line;
• with the help of LSHM, you can level a wooden surface or give the desired shape;
• allows you to make smooth rounding of elements.

In order to choose an LSM, you should first of all decide for what purposes you will use it in the future. The main distinguishing factor of LSHM is the classification of abrasive belts that are suitable for the grinder.

The smallest versions of LSHM can work with belts only 6, 3 cm wide. Their advantage is that they are very light in weight and can be used with one hand.

Bigger brothers can handle belts up to 12 cm wide. They can be used for large areas. They are ideal for leveling. The best option for a home craftsman may be a tape machine that works with a 760 mm tape.

The next parameter for choosing a LSM is the duration of its use. If you need it for light jobs such as finishing small items or hobbies, then a simple, inexpensive typewriter may also work.

For construction, it is better to take a more serious option. Naturally, it costs more, but they, as a rule, do not lend themselves to rapid wear and tear, and the proverb "The miser pays twice" is just what comes in handy.

When choosing an LSM, you should also pay attention to its additional parameters:
1. speed control;
2. automatic centering of the belt (prevents the abrasive from flying off the rollers);
3. dust collector.

The main difference between brush grinding tools is that the working part is represented not by a grinding cloth, but by a brush mainly made of metal. Therefore, such a tool for grinding or polishing will not work.

It is used to remove coatings. The wood brush sander is designed for working on large areas, such as removing varnish from parquet floors, renovating furniture or other bulky items.

Also, this type of grinding machine is used to "age" wood. With the help of a stiff brush, the wood is given an ancient look, and such an element looks antique.

The second name is the orbital sander. This tool is similar in principle to an orbital sander (VGM). The difference is that eccentric machines are more productive, grinding is more accurate and thinner, and the very principle of operation occurs due to the complex trajectory of the moving element.

Grinding is carried out with a disc with a diameter of 15 cm. Abrasive circles of different grain sizes are attached to the disc using the Velcro method.

This type of grinding tools has a significant drawback: education a large number dust. Manufacturers understand this and are working to improve the tools.

Some models have dust collectors. This model can be easily used indoors. Therefore, if you plan to work indoors, it is better to take this into account when choosing and look for models with dust collectors.

An orbital sander is often used for fine sanding or polishing wood surfaces. It is also suitable for removing coating material, varnish or paint. Grinding is carried out by oscillatory circular motions with a small amplitude.

In some models, the oscillation speed and amplitude can be adjusted. Sanding takes place with sheets or circles of sandpaper (which will be an abrasive material, a sheet or a circle depends on the model), which are attached with Velcro or a clip.

Which sander is better belt or vibration sander

For a beginner, it is not a tape tool that is more suitable, but a vibrator. There are many reasons for this, first of all, it should be noted that tape machines are used for rough surface treatment, since the thickness of the removal of a layer from the surface can reach several mm. In order to use a tape machine, it is necessary to take into account not only the size of the skin, but also to calculate the force with which you press the machine and, with small errors, arise big problems with a processed surface. Vibrators are easier to use, do not leave streaks, and with the correct selection of skins, even a child can handle this device.

Of course, it is much easier to work with a vibration machine, and making a hole on a wooden surface with a tape machine is a piece of cake.

Which sander is better eccentric or vibration

The vibration and eccentric sander are different in the shape of the sanding platform and are easy to distinguish.

The vibrating sander has a rectangular sanding platform, the eccentric sander has a round one. Accordingly, if you need to grind a flat surface in a corner closed on three sides (for example: a step of a staircase), the vibrating sander is out of competition here.

With a circular sanding platform - there are always untreated areas in the corners, But the eccentric sander has its own specialization: using a soft sanding platform, it is able to flawlessly process a convex or slightly concave surface (for example, a car wing).

The two tools also differ in labor movements. With a vibrating machine, individual grinding grains move in a circle with a diameter of several millimeters. The coarser the grain grinding wheel, the more noticeable the traces of processing.

When the eccentric sander is in operation, two independent movements are added. Therefore, the grinding grains are constantly moving, describing a complex path. As a result, the surface is polished more evenly and better.

Additional rotation also significantly increases productivity. But be careful, the fast rotating grinding wheel can easily damage the sanded surface if it is awkwardly moving. Deep scratches are very difficult to remove.

Eccentric Sanders at a Glance

For DIYers, there are eccentric sanders with a maximum grinding wheel diameter of 125 mm. Professionals prefer more powerful tools with a grinding wheel diameter of 150 mm.

Eccentric machines combine two working movements: circular eccentric plus rotation, which makes possible both high processing performance and the finest grinding. At a good price, both types of machines can be bought during frequent promotions in the skbtools.ru store, as well as other necessary construction tools.

The sanding pad brake will prevent the development of high rpm, which reduces the huge time spent on the operations - lapping. And even with a large thickness of the removed layer, deep scratches and scuffs do not remain on the treated surface.

By design, eccentric grinders are available with vertical and horizontal motor. Accordingly, they have a different design of the gearbox that transmits the movement to the grinding plate.

But the consumer is primarily interested in the usability of the tool, how comfortable the tool is in the hand. The weight, the shape of the arms and their number are all important.

Painters and joiners are more likely to use lightweight grinders with a vertical motor and a mushroom handle on top. Such a tool can be used with one hand, on vertical and overhead surfaces.

Craftsmen who make a living repairing cars prefer an eccentric sander with a horizontal motor and an additional handle, which can be guided with both hands. This requires precision and excellent handling.

The eccentric sander is usually used for grinding and polishing, that is, in finishing operations. It makes sense to use this type of machine loop when high requirements are imposed on the quality of processing, and the appearance of deep scratches on the treated surface is regarded as a defect.

Grit, or roughness, is a key parameter for any type of sandpaper. The grain size is always indicated on the back sandpaper after the letter P or the word Grit, sometimes both variants of designations are used at once. The grain size is defined by a number from 12 to 15000, sometimes even more.

In its simplest form, this figure is the number of abrasive particles per square inch, if they are scattered in a continuous uniform layer. In reality, this number is determined by the number of wires per square inch of the sieve through which the abrasive has been sieved.

The actual size of the particles ranges from visible to the naked eye (1–1.5 mm) to completely microscopic (whole and tenth microns).

Let's define the area of ​​application of sandpaper depending on the grain size:
• up to P80 - for rough roughing and grinding in order to level the surface;
• from P100 to P220 - used at the second stage of grinding, if you need to eliminate small grooves and scratches;
• up to P280 - used for fine grinding;
• smaller skins are already classified as polishing skins.

The rule for choosing sandpaper by grit is very simple - the higher it is, the smoother the surface will be after processing. But at the same time, the finer the sandpaper, the faster it grinds down, and the removed layer of material becomes smaller.

It should also be borne in mind that the greater the hardness of the processed material, the coarser paper can be used for finishing. At the same time, on soft wood, even with a grit in P220, quite distinguishable scratches can remain.

Dry and wet sanding

Depending on the abrasive material and its binder, the abrasive paper may differ in its tolerance for wet sanding. Besides the fact that wet sanding papers are more expensive than regular papers, there are a number of reasons why this distinction is important.

When removing particles from the treated surface, the friction forces at certain points can be so high that the generated temperature is sufficient for sintering metal dust.

This, in particular, is true for aluminum and most non-ferrous metals: if the skin is not periodically shaken off, it will quickly clog and become unusable.

In some types of paper, this problem is solved with a special abrasive material. So, silicon carbide, especially applied by electrostatics, is capable of crumbling, forming new cutting edges, so this paper practically does not clog.

However, there can be really a lot of particles of the removed material, for example, when processing plastic, and then it is necessary to prevent their adhesion by moistening sandpaper with water.

Resistance to wetting is determined by the standard, which is indicated at the end of the marking on the back. Paper in accordance with GOST 13344-79 allows work in a humid environment, and according to GOST 6456-82 it does not.

There are exceptions, because water resistance is generally determined by the type of binder, that is, glue. Although the type of binder is usually not indicated, abrasives bonded with synthetic substances: bituminous, polyester resins, phenolic varnishes, etc. are suitable for wet processing.

Very often the possibility of using paper for wet works is additionally indicated by the letter "B" or the word Waterproof.

For manual processing

Often, the home craftsman has to process his products by hand. So the quality of grinding is much higher, there are fewer untreated areas. For manual processing, paper is available in sheet, tape and roll formats.

Tissue paper P60, P80 and P120 are the most popular types for grain size on the farm. The finer skin usually has a paper backing. It is recommended to always keep in stock different numbers of fine abrasive papers up to P400.

Cloth-backed abrasives with a grain size greater than P300 are mainly produced for machine processing, although they can also be worked by hand with varying success.

The main difficulty is that the abrasive is covered with a solid layer of binder, and processing with such a belt by hand is extremely slow, especially with high grain sizes. However, it is a pleasure to carry out wet sanding with such paper.

Also, for manual processing, polyurethane sanding sponges will be very useful, with which it is very convenient to process parts with fine relief. If you are fond of woodworking, always have a supply of foam rubber skin, this is the effective remedy for preparation for painting or varnishing.

When buying consumables for grinding machines, it's hard to go wrong. All of them have a specific type and working dimensions - either length and width, or size number, or diameter.

For belt sanders and grinders, cloth-based paper rolled into a ring is used. Length and width in millimeters is the main parameter of such sandpaper, determined by the suitability for use with a particular tool.

If you can still play with the width, using a narrower tape or tearing off the excess, then tapes of any length can only be used on grinders with adjustable tension. Also note that only one direction of travel is valid for the ring belt, indicated by the arrow on the back.

It's even easier with abrasive papers for rotary and delta sanders. They either fit or not - the size of suitable consumables is clearly indicated in the equipment instructions. When choosing, you must also pay attention to the position of the dust extraction holes.

Since we are talking about a power tool, almost all sandpaper in consumables is designed for dry sanding. It remains only to choose the right grain size according to the type of material and the desired surface quality, and then gradually reduce it during processing.

It is not at all difficult to make a belt sander yourself, you must complete the following steps:
1. select suitable materials and parts;
2. do a solid foundation for fixing the tool;
3. install a suitable countertop;
4. fix the vertical struts with a tensioner and a drum;
5. mount the motor and drums;
6. fasten the sanding tape.

To process fairly large parts and elements, it is necessary to make a large copy of a serial grinder. For example, if we take an electric motor with a power of 2 kW or more powerful with a rotor speed of 1500 rpm, then the gearbox can be omitted.

The power of such an engine is quite enough to rotate a drum about 20 cm in diameter and process parts about 2 m.

You can also use Electrical engine from an old washing machine. In this case, the frame is made of a thick sheet of iron, preparing a place for installing the motor and carefully fixing it with bolts to eliminate vibration.

The design of such a machine consists of 2 drums, and one of them is fixed, and the second can be pulled and rotated on bearings around an axis. It is advisable to make the base for the machine from metal or several sheets of thick plywood.

Drums do on lathe from chipboard. The tape is cut from sandpaper sheets with a width of about 20 cm and fixed on the bed. The larger the table size, the larger the parts can be stacked and processed in the future. Drawings of finished products can be found online.

From the grinder

Many may say that the "grinder" is the same is an angle grinder, but there are some subtleties hidden here. It should be borne in mind that angle grinders have very high revs and often quite a decent weight.

To polish the surface with a grinder, you must have considerable experience in this matter and use special polishing discs and wheels. The sander has a much lower engine speed and weight. To work with a factory grinder, no particular experience and dexterity is required.

It is possible to independently make a good grinder out of a grinder, which is not inferior in its parameters to a factory machine, only by modifying it electrical circuit, by mounting the regulator at a lower speed and by using special grinding attachments.

From a drill

To turn an ordinary household electric drill into a grinder, you need to equip it with a special attachment - a working drum or a special support plate, depending on the task at hand.

The backing or sanding pad is a plastic or rubber base with sandpaper glued on and a shank for clamping into a drill chuck. Trays with a flexible shaft are suitable for work with a loose drill, while with a rigid one it is better to use only for a well-fixed drill.

Grinding drums for household drills are structurally a conventional cylinder, a shank and sandpaper glued to the cylinder. When using drums, the working surface of the grinder is parallel to the axis of rotation.

From a computer hard drive

Any old hard drive can be converted into a miniature sander.

To do this, follow these steps:
• completely disassemble the hard drive and remove from the case everything that is located to the left of the magnetic disks;
• cut out the working circle from sandpaper, make a hole for the spindle in the center of the circle;
• stick several strips of double-sided tape on the rotating disk of the hard drive and fix sandpaper on it;
• make a protective screen that protects the eyes from the possible departure of the manufactured emery disc;
• connect the finished structure to the power supply from the computer and use.

Of course, this design does not have high power, but it is quite possible to sharpen a small knife or scissors.

Brushing is a method of artificial aging of wood, which involves the use of specialized tools and techniques. The brushing technique is based on the mechanical processing of wood with special metal brushes, with the help of which the softest upper fibers of the material are removed.

Thanks to this technique, the hard surface of the wood is exposed, on which the texture of the material and the structure of the growth rings are clearly visible, as well as a beautiful relief is formed, emphasizing the aesthetic appearance finishing material... However, the brushing process does not end there.

To emphasize the relief and make the structure of the wood even more distinct, it is highlighted with a color that gives saturation to natural shades.

To do this, an uneven coloring of the surface treated with a metal brush is performed, while the cavities formed as a result of the removal of soft fibers are painted in darker shades, and the surface of the texture - in lighter shades. Thanks to this technique, the relief of the wood becomes as noticeable as possible.

Important! In order for artificially aged wood to acquire the maximum resemblance to the material, the aging of which took place in the natural environment, experts recommend dyeing the material that has previously been brushed in gray. Without waiting for the paint to dry completely, it is lubricated from the embossed surface.

The artificial structuring method can be used in the processing of both hard and soft woods. The main requirement that the wood to be brushed must meet is the presence of a clearly defined texture and well-visible layers of different hardness.

These materials include oak, pine, walnut, larch, wenge and ash.

As for alder, cherry, birch, teak, maple and beech, the brushing method will be proven ineffective for these species, since a distinctive feature of these trees is a fine-fiber structure without pronounced layering.

On a production scale, the volume of work is several times higher, and therefore, it becomes necessary to automate the process, which implies the use of special machines.

This simplifies the work of making aged wood, and also reduces time costs, allowing you to carry out large volumes of work in a short period of time.

If you want to purchase special machines for brushing wood at home, it only makes sense if you plan to perform a large amount of work. Let's consider the most common models of stitching machines.

FESTOOL RUSTOFIX RAS 180 wood stripper or so-called wood brushing machine.

Three brushes are supplied with this device:
1. The first steel wire brush used for the primary processing of wood;
2. Second synthetic bristle brush for intermediate sanding;
3. The third - from sisal is used for polishing the treated surface.

The Makita 974 sander can also be used for brushing wood, but it can be difficult to work with in corner areas.

In this regard, at the joints between the walls and the floor, it is necessary to additionally use an angle grinder equipped with attachments.

The Felisatti AGF 110 / 1010E sander can be used for processing both relatively flat and uneven surfaces. Metal and nylon brushes are supplied with this device.

It has an analogue - an Interskol sander, wood brushing with the use of which will be much easier if you follow the instructions presented in our article.

Wood brushing tools

At first glance, the process of artificially structuring wood may seem complicated, but even an inexperienced craftsman can do it if he has a certain set of tools at his disposal that save time and effort spent on work.

In addition, it should be noted that wood brushing can be done both manually and mechanized way, which is largely determined by the tool used.

Depending on the method by which the wood is brushed, the tool is of the following types:
• Manual metal brushes

They are characterized by various thicknesses and stiffness of bristles and are used for primary processing of wood. The stiffness of the bristles is determined by the length of the wire; the longer it is, the softer the bristles.

When choosing a brush for brushing wood, try to give preference to tools with the stiffest metal bristles. If necessary, it can be trimmed with a grinder, making the pile even harder.

Using a brush for brushing wood, it is necessary to move its bristles along the fibers in exactly one direction. With this technique, you can remove soft fibers from the surface of the wood, leaving the hard fibers intact.

• Manual chisel

A tool with which you can make deep longitudinal grooves of various curvatures in wood fiber. With skillful use with the help of a chisel, you can achieve the maximum realism of artificially structured wood by applying sufficiently deep cracks, creating the effect of cracking the material.

• Coarse sandpaper

It is also used in the process of brushing wood and allows you to emphasize the texture of the material, making the natural pattern clearer.

The technique of using sandpaper is similar to the technique of using a hand brush - it is also moved with pressure along the fibers, as a result of which grooves are formed on the surface of the wood, the structure of which is similar to the structure of natural fibers.

By choosing the correct grit size and using sandpaper with different grit sizes, you can achieve different depths and severity of grooves.

• Grinder equipped with special brush attachments for brushing wood

Another tool that is used for brushing wood. At the same time, at the initial stage, for rough surface treatment, nozzles with metal pile are used, and for the final stage - with copper and sisal pile.

Currently, a special nozzle for brushing wood "Piranha", which is an abrasive polymer brush, is in wide demand. By using this tool, you can selectively remove fibers by focusing only on soft fibers and not touching on hard fibers.
