Large wood sanders. How to choose a reliable wood sander - all parameters and types

We devoted previous articles to screwdrivers, angle grinders, chain saws, jigsaws, mixers, spray guns, miter saws, jackhammers, and hammer drills. Today, all our attention will be focused on the tool that uses sandpaper.

Sanding or aging a wooden part, removing paint and varnish, removing rust, grinding off burrs, rubbing putty, processing plastic, polishing stone - all this and much more can be done with modern grinding machines. So, we offer the slogan: “Choose a grinder with us, choose like us, choose better than us!”

Sanding: This process causes discomfort for many people, even at the mere mention of it. What can I say, grinding is a monotonous, labor-intensive, painstaking, dusty, sometimes noisy, slightly harmful operation, but, unfortunately, inevitable. Modern requirements finishing work has reached unprecedented heights, no one doubts the fact that the planes must be perfectly even and smooth. Finishing high-tech coatings are increasingly striving for thin layers and only highlight the shortcomings of the base. Even enlarged sheets with ready-made decorative coating building materials have to be joined, followed by caulking/puttying or seam sealing followed by sanding. Domestic builders, finishers and shop workers (manufacturers of furniture, carpentry, stone products, bulk polymers, metal) are slowly but surely getting used to new standards, previously unknown.

Fortunately, the hardware did not lag behind for long: the working people are helped to cope with the task by a highly specialized, relatively inexpensive tool - grinding machines, which we can no longer do without. Gone in the past is the painfully familiar sandpaper attached to wooden block, or clutched in the hands. The leaders of capitalist production have produced many, many wonderful professional grinding devices designed for any occasion, without neglecting home craftsmen who love to create anything. with my own hands. Understanding the variety of grinders and making the right choice is actually not difficult, the main thing is to know what a particular tool is intended for, and also clearly understand what tasks you will set for the grinder.

It is customary to distinguish three main types of grinding machines: belt, eccentric (orbital), surface grinding (vibrating). They all have their own specialization and form a unique cascade of capabilities, ranging from fast rough processing to delicate finishing grinding. Many of those who are closely associated with grinding “on duty” have in their arsenal a full set of tools of this class. Belt sanders are the heavy artillery for removing large layers from large surfaces. PShMs are oriented towards finishing. And ESMs are capable of producing even better results, bordering on polishing, but, compared to vibrating machines, they have a different operating principle and a different filling.

Belt sanders

Above, we inadvertently called the belt sander heavy artillery; in fact, it would be more appropriate to say “tank”. The working element of this well-recognized tool is an abrasive belt, glued together in the form of an endless ring, which moves along two end rollers and clearly resembles the track of a tracked vehicle. Such units are relatively powerful, they have a relatively simple reliable design(angular gearbox plus V-belt drive), low center of gravity, solid speed of movement of the abrasive material. Using a belt sander, you can easily remove a layer of material of a few millimeters, make an edge or rounding on a workpiece, or remove old paintwork or rust. The following are subject to it: wood, metal, polymers, mineral building materials... Clear paint from floors - yes, correct planed timber - please, level up a putty wall with defects - no problem. However, it is worth understanding that high performance is not best friend quality, there will definitely be scratches and chips. For finishing sanding you will need to use an orbital or surface sander.

It is no secret that the performance of an electric tool is directly proportional to the power consumption of its motor - the higher it is, the more we can squeeze out of a particular unit. In the case of LSM, the consumer has the opportunity to choose from models with a motor from 0.5 to 1.2 kW (Skil Masters 7660MA - 1200 W).

Please note that tools from Chinese brands are often stated with inflated engine power ratings, or, if there are indeed stated watts, they are not balanced with the rest of the characteristics of the device. Record power is boasted by those manufacturers who have nothing else to show, except perhaps the heavy weight and bulkiness of the “unique” product.

The next important characteristic for a belt sander is speed. Obviously, it also needs to be taken into account to determine the capabilities of the tool. A fast machine will do more, but it will not be possible to pin it down if its outstanding speed is not supported by additional power. The reason for this is the notorious torque, which says that the more speed a tool has, the less power it has left. A responsible manufacturer carefully balances these characteristics, making them mutually changeable, for which smart electronics are sometimes responsible. The belt speed in these grinders can be in the range of 150-550 meters per minute (Fiolent MSHL1-100 - 550 m/min.).

The question may arise: why produce fast but relatively weak blades at all? It’s just that a super-productive (fast and at the same time strong) car is more difficult to control, it is heavier, larger, and more expensive. If pressed excessively, it can easily ruin the workpiece. In turn, with maneuverable, high-speed lightweights, it is convenient to process a large surface area in a short time, often “on the spot.” If you don’t yet know what kind of loads await the grinder, choose a slower model that can be pressed a little, so it will be more versatile. Even more versatile are blade grinders with the ability to preset the speed mode (Sparky MBS 976, DeWalt DW433). Among them there are options with smooth or stepped adjustments.

It's time to talk about electronic systems, which help in working with belt sanders. These machines are not rich in electronic components, compared to other types of electric tools. Everything is usually limited to regulating the speed of the belt. The switch responsible for this function is made in the form of a slider or a wheel with divisions. There are models with overheating protection (Metabo BAE 75). With some stretch, this includes the function of fixing the start button in the on position.

The situation is much more interesting with mechanical “bells and whistles”. The kit may include a stand or special clamps designed for stationary fastening of the tool (very convenient for processing small parts). The grinding frame serves as a kind of limiter that helps to avoid damage to the workpiece. A rip fence or miter gauge is useful for obtaining an accurate bevel or a smooth, parallel surface. The thin front roller in some LBMs (Black&Decker KA88) has a small diameter, which allows the dead zone in the inner corners to be reduced to a minimum. Automatic centering of the belt (the cunning barrel-shaped shape of one of the rollers) does not allow the latter to treacherously slide off at the most inopportune moment. An additional handle with variable tilt or removable will significantly increase the functionality of the machine in “squeezed” places - sometimes noticeably.

Special attention should be paid to the dimensions of the working plane - the sole, respectively, the length and width of the tape. Wide soles (100 mm) are typical for powerful professional models, making them more stable and productive. The hobby class is usually limited to 75 millimeters. The long and wide sole of expensive blades has a complex design, consisting of a backing and an elastic plate, which allows for constant, uniform contact between the sandpaper and the part; such a tool “holds its plane” well. It is necessary to mention “ribbons” with narrow equipment - these are the so-called “electric files”, which are not very powerful and versatile, but specialists value them for their unprecedented compactness (for example, Makita 9032 with a tape only 9 mm wide).

All belt machines have a dust removal system, but not all of them work equally effectively. The fight against dust is carried out either using a vacuum cleaner connected through the pipe, or by collecting it in a bag with a built-in filter. Of course, a vacuum cleaner is preferable, especially when sanding mineral substrates. In ultra-cheap models, the impeller responsible for air suction does not cope with its function, the channels quickly become clogged, and a lot of harmful “flour” remains in the air.

Surface grinding (vibrating) machines

If we take into account the cleanliness of the processing of parts, then surface grinders occupy an intermediate position between belt and orbital ones. With their help, they carry out finishing grinding of flat surfaces made of a wide variety of materials - plastic, wood, stone, metal... Thanks to the relatively large working plane, the PSM is suitable for working with serious quadrature. The secret to the popularity of vibrating sanders lies in their moderate cost, the availability of equipment elements, and the absence of dead processing zones (the flat, out-mounted sole easily handles corners).

The main working body of a surface grinder is a plate, which makes frequent reciprocating movements with a small amplitude. The motor in such machines is located vertically, which makes it possible, using the “eccentric-counterweight” tandem, to convert the rotational movements of the shaft into translational movements of the platform.

Most vibrating grinders traditionally boast a motor power of 150-300 W; they are quite maneuverable, moderately light and compact. This level of power plant is almost always sufficient. However, such unanimity among manufacturers would be, at least, strange - there are models with a power of up to 600 W (Makita 9046). They are, of course, heavier and larger, but can work at low speeds for a long time without overheating.

The most important indicator of the PSM is the amplitude of the sole stroke. It may vary in different models, although it is invariably a relatively small value. On average for the class, the platform moves by 1-3 mm; in more mobile models figures of 5-6 mm may appear (Festool RS 100). A larger amplitude helps to polish the surface faster, but such processing will also be rougher.

Another nuance is the frequency of the sole stroke. At high speed the machine will quickly remove a relatively thicker layer, while at lower speed it is easier to achieve a precise finish sanding. Some manufacturers make the platform movement frequency variable, exceeding 20,000 strokes per minute (Bosch GSS 280 AE L-BOXX), which allows you to adapt to the processing various types materials, tailored to the characteristics of specific surfaces.

When choosing a vibrating sander, special attention must be paid to the platform. With its dimensions, everything is quite simple, there are two options: a kind of “standard” and “mini” models - the plate area is about 100 mm 2 (Makita BO4557, Sparky MP 250). Toddlers are good for tight, tight spaces. Obviously, the sole must be of high quality, perfectly flat, with clear geometric shapes. Budget machines are equipped with a platform made of steel or high-strength plastic, while more expensive analogues are equipped with cast platforms made of alloys containing aluminum or magnesium (Festool RS 100). A good sole is characterized by precise balancing, which is easily determined by a low degree of vibration when operating without load (idling). It is also important what the pad is made of; the most suitable option is a porous polymer; it “holds” the plane better than rubber.

Vibratory grinders with a delta-shaped platform are included in a separate class; they are popularly called “irons” (Hitachi SV12SH, Makita BO4565). Due to their miniature size and good maneuverability, they are used for processing objects with small parts and complex surfaces, such as furniture, carpentry, staircase elements, and car body. Their triangular platforms are rotary - you can continue to work unevenly “eaten” by the sandpaper petal (Festool Deltex DX 93E) or removable (with quick installation another type of platform - for concave/convex surfaces, for structuring, polishing, rubbing).

Emery can be attached to the site in different ways. It is more convenient when the paper is secured with Velcro, but special equipment is relatively expensive. The option with spring-loaded clamps is somewhat more complicated, but you can use inexpensive sanding paper that you cut yourself (you just need to make holes in the right places for dust removal).

The fight against fine dust, which inevitably forms when using a grinder, poses many challenges for developers. They have to work hard to protect all mechanisms. In this case, special motor sealing, protected bearings and switches, an impenetrable housing, and a channel system with forced dust extraction are used. To ensure that dust is removed from the work area and does not saturate the air, it is directed into a collection bag or filter; in most cases, a vacuum cleaner can be connected to the nozzle - this is the most effective method protection.

Eccentric (orbital) sanders

This type of sander is designed for high quality processing. Delicate grinding and even polishing are their element, although the performance of such devices can be no less impressive than that of vibrating machines. They can handle any material; most often you will find ESMs among woodworkers and car painters. When working with profile, volumetric, curved objects, eccentric sanders have no equal, and they also have no problems with planes. The only place where such a machine fails is in corners and small recesses - the “plate” simply won’t reach there.

Just like surface grinding units, “orbitals” have an eccentric and a counterweight, with the help of which the round grinding plate not only moves around its axis, but also along an “orbit” with a small amplitude. Interestingly, axial movement usually occurs by inertia, and in some models it is forced (via a gear transmission - Kress 900 MPS). Such complex movement of the working blade, coupled with the highest rotation speed, is precisely what makes it possible to obtain a surface excellent quality, without depressions, waves and scratches.

From 200 to 900 watts - this is how much the motors of modern electric motors consume. Those that are more powerful will naturally be more productive; they can easily handle a larger sole, up to 150 mm in diameter (for example, the 400-watt Bosch GEX 125-150 AVE or Interskol EShM-150/600E).

Bosch GEX 125-150 AVE

Orbital machines also have differences in the speed of translational motion. If we talk about rotation, this figure can be from 4 to 14 thousand eccentric revolutions per minute for models with adjustment (Metabo SXE 425), and about 12,000 for models without it. If we talk about the concept of “fluctuation”, then these figures will be half as much. In fact, everything is simple here: the higher the speed, the rougher the processing will be, but the faster the work can be done.

The eccentric of orbital machines may not have the same “span” - from 2 to 7 mm (Festool WTS 150/7 E-Plus). This is called the amplitude of the oscillation. The smaller it is, the less vibration the device generates, the more compact the plate moves, the smaller the area we process, but the cleaner the grinding will be. In some ESMs, the operator can set a certain amplitude, affecting the productivity and fineness of grinding.

Compared to their counterparts (LSM and PShM), “orbitals” are usually well stuffed with electronics. We have already talked about setting speed and amplitude, in addition to this professional tool They are equipped with an automatic frequency maintenance system (Bosch GEX 150 Turbo) so that it does not drop under load - this is constant electronics. Some models have an electrodynamic brake (AEG EX150ED K), which, after turning off the “start” button, instantly stops the work plate, preventing damage to the workpiece and reducing the possibility of injury. For powerful professional machines, a starting current limiter can be provided (Makita BO6040 ), which smoothly accelerates the tool, preventing a starting jerk and protecting the network from short-term, but significantly increased load.

One of the very nice options is the removable network cable, adjustable or removable front handle, locking start button, functional dust removal.

Be sure to pay attention to the type of sanding pad. Firstly, if you need particularly delicate processing, do not chase a large plate; by the way, it has a larger dead zone and an amplitude of about 5-7 mm. The plate, made of metal, has stability, high strength and excellent heat dissipation. The elastic plate copes well with convex surfaces. All of them have Velcro for fixing the sandpaper and holes for dust extraction. These holes from individual manufacturers may vary in size, number and location; according to this feature, you need to select the appropriate equipment.

If financial issue is not the least important, then for a home workshop you can purchase a model from the “hobby” category. Good examples are offered by Makita, Black&Decker, Skil, Sparky, Bosch. Look towards the domestic manufacturer - Interskol and Fiolent have noticeably improved in terms of the quality and functionality of their tools.

Pay attention to the weight and dimensions of the product you are interested in, especially if a lot of work is planned “on the spot”, on weight, on outstretched arms. Give preference to a car that is not too powerful, but rather a faster one; it will be lighter, more compact and cheaper. But for regular operations on a workbench, the large weight of the device will be more of a plus than a minus.

Be sure to “feel” the grinder thoroughly and find the one that best suits your ergonomics. Decide on the type of main and additional handle; most likely you will have to choose between a “mushroom” and a “brace”. See if the switches are conveniently located and how they work, how easy it is to change the equipment, and whether the power cord is in the way.

Check the moving parts of the product for play. Look at the accuracy of the fit of the body parts. Turn on the car in a tool store, at least at idle speed, evaluate the level of noise and vibration. Ask about the cost, range and possibility of interchangeability of consumables.

Weigh all the pros and cons, take your time with the choice, then the whole repair will go smoothly.

Sanding machine for the car greatly facilitates the process of polishing and grinding. In addition, the ability to use fine abrasives ensures uniform processing of the body vehicle and reduces the likelihood of complete erasure paint coating. However, to carry out successful manipulations using this device, important nuances regarding its parameters and operating principle should be taken into account.

Types of grinding machines

The modern market offers the following types of machines for grinding and polishing cars:

Purpose and design features

• tape - different high level productivity, used to process large areas. Sanders of this type perform their functions due to the circular movement of the abrasive belt, which is very similar to the movement of a tractor caterpillar. Most often, a special dust collector is included in the kit, which prevents the dispersion of waste particles. Difficulties in using the unit rarely arise - it is easily installed on the required surface, and all that is required of the car owner is to make uniform movements and monitor the result;
• vibration (surface grinding) - the main working element of such devices is a rectangular sole on which the abrasive is fixed. The sanding paper, depending on the features of the device, can be attached in two ways: using Velcro or a clamping mechanism located on both sides of the sole. Grinding and polishing of a car is carried out by reciprocating movements with an amplitude of about 2 mm;
• delta grinding - differ from vibrating grinders only in the triangular (like an iron) shape of the sole, which can move around its axis or in orbit. Used to treat hard-to-reach areas;
• orbital (eccentric). These grinders have a round base to which a grinding wheel is attached. All processes are carried out thanks to the simultaneous rotation of the sole in orbit and around its axis, which allows the work to be completed in a fairly short time;
• angular – provide high-quality grinding through a grinding wheel that rotates around its axis. Externally, an angle grinder is very similar to an angle grinder and can be used not only for grinding, but also for cutting various materials. For infrequent use, an angle grinder with a disk diameter of 115 to 125 mm is perfect, while a grinding tool with a disk diameter of 180-230 mm is classified as professional.

Power supply

• air (pneumatic) - characterized by high performance and electrical safety. But servicing a pneumatic car machine is enough complex process, requiring constant pressure and uniform air flow. A significant disadvantage is also the thick hose, which complicates the grinding process and makes it inconvenient. Such devices are most often used in factories or large service stations, where specially trained specialists can ensure proper functionality;
• electric powered by a battery - used if it is not possible to connect to the electrical network. Due to limited battery capacity, they are designed for processing small surfaces and are characterized by low power;
• electric powered by electricity - such machines are used most often due to their convenience, high performance, as well as the price indicator, which varies depending on the model and design features, that is, this type of grinding tools is affordable for any car owner.

How to choose a grinder?

When choosing grinding devices, you need to pay attention to the following features:

• power, which determines the duration of operation of the device and the speed of rotation of the disk. The higher this indicator, the greater the amount of work can be;
• weight. The lighter the grinding machine, the more accurate the processes performed with its help, but the processing time increases. On average, the weight of such equipment is 1-2.5 kg;
• disk diameter - must match the standard size of the device;
• disk rotation speed - high-performance devices can provide up to 20 thousand revolutions per minute, which is necessary for serious body processing, for example, in preparation for painting, while 5-6 thousand will be enough. It is desirable that the purchased device has a function for adjusting the disk rotation speed;
• When purchasing an orbital sander, a very important parameter is the eccentric stroke. The lower this indicator, the better the process is performed, but at the same time, the higher this parameter, the faster the processing will occur. Standard models are characterized by a stroke of two to six millimeters. There are machines that allow you to adjust the eccentric stroke, but they are quite expensive.

Proper Use

High-quality polishing and grinding of a vehicle can be achieved by following these recommendations:

• divide the surface into several sections and process each of them in turn - this will prevent the abrasive or polishing agent from drying out;
• at the beginning of work, the speed should be minimal and after distributing the abrasive over the surface, it is necessary to turn on increased speed;
• during operation, it is necessary to periodically turn off the grinding machine - this will allow the car body to cool and prevent it from overheating;
• when carrying out body treatment, it is necessary to ensure uniform pressure on the sole area, and movements should be smooth;
• during the manipulation process, the grinding wheels are periodically cleaned with a brush;
• If an uncharacteristic sound appears during operation of the tool, it is necessary to thoroughly check, clean and lubricate it.

Despite the fact that a sander speeds up and facilitates repair work, its use still requires care and attention, because if the tool is used incorrectly, it may be necessary to completely replace the car’s paintwork.

This article is intended for anyone who works with wood and wants to make sanding easier. Sanding wood is a labor-intensive process that can be made much easier with the right tools. Belt, oscillating or eccentric, as well as deltoid sanders are suitable for processing wood. There are several types of tools for finishing wood on the market: belt sanders, eccentric sanders, orbital sanders.

How to choose a wood sander, which is better, belt or vibrating, which type of device is best suited for specific purposes? Before finding the answer to these questions, we should understand how different models differ and compare their functions with our needs.

Types of wood sanders

The right choice appliance for home or dacha depends on the type of work performed and the features of the workpiece:

• form;
• size;
• grinding corners and hard-to-reach areas;
• type of coverage.

Different tools are suitable for specific jobs:

• a belt sander is chosen for sanding large, flat surfaces;
• An eccentric sander allows you to conveniently process convex and concave small wooden surfaces;
• the oscillatory (vibrating) model has a similar application, with the ability to handle corners thanks to the rectangular sole;
• The delta-shaped wood sander is ideal for processing surfaces with complex shapes that are inaccessible to most sanders; a small sole area is recommended for small wooden surfaces.

Tape

Model description

If the surface is large and relatively flat, it is better to choose a belt sander. It is designed to process:

Belt sanders are characterized by the highest efficiency, used in workshops, rarely for homework.

Thanks to their high productivity, belt sanders can cover large areas in a short period of time with excellent results. The treated surface is smooth and uniform. Since belt sanders are primarily used for linear motion, they are ideal for sanding along wood fibers.

The disadvantage of belt sanders is that the base design does not allow access to hard-to-reach corners. The edge of the belt is not also the edge of the soleplate, so surfaces, for example near a wall, are inaccessible to the belt sander. In this case, you will need a deltoid model.

Which tape model to choose?

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

• Speed ​​of movement of the working part– the higher the speed, the faster and more accurately the surface is polished. Depending on the model, the speed can vary from 200 to 420 rpm.
• Tape size affects the speed and accuracy of grinding. The larger the size, the faster the grinding occurs, but the accuracy decreases.
• Power– the higher the power, the better the tool processes a hard, complex surface (hard deciduous wood - oak). Thanks to its high power, the tool can work longer without overheating.

Power selection

• Draw machines with motor power up to 1000 W are designed for light work,
• Models with a motor power of more than 1400 W work well under short-term but heavy loads.

Model overview

Eccentric or orbital

Purpose of the tool

Eccentric machine – universal tool, designed for sanding convex, concave small wooden surfaces and other materials.

The model is used for:

• wood sanding;
• grinding metal surfaces;
• polishing, thanks to the possibility of installing a polishing disc;
• cleaning old paintwork.

Disadvantage of the model: round shape the sole does not allow for corner processing.

The working surface is smaller than that of oscillating machines. The diameter of the working part is usually 125 or 150 mm. The larger the working surface, the higher the productivity.

A small work surface has pros and cons:

• advantage - it is easier to work with in hard-to-reach places,
• cons – less performance on large surfaces.

Tool options:

• Eccentricity– has a significant impact on the performance of the tool, means deviations of the movement of the sole from the turning point. The higher the value, the more accurate the tool is.
• Disc diameter– large diameters allow you to quickly process large surfaces, small diameters are suitable for working in hard-to-reach places.
• Number of revolutions per unit time- how larger number rpm, the more accurately the tool works (as in an oscillating machine).

Model overview

Oscillatory (vibration)

Main Features

An oscillating sander is used for sanding flat, even surfaces, ideal for processing wooden objects:

• furniture,
• countertops,
• doors.

Unlike the eccentric model, oscillating sanders are equipped with a rectangular base that allows you to sand corners. Larger models are more powerful, their soles have a rectangular or square shape.

Options

• Outsole size– the more, the faster the surface is processed. When working with small surfaces, it is better to choose a sander with a smaller soleplate, this will allow you to more accurately process hard-to-reach areas.
• Number of vibrations– the higher, the better the tool works. Usually expressed as the number of vibrations per minute.

Model overview

Deltoid sanders

Model description

The main difference between delta-shaped sanders and oscillating sanders is the sole. Its shape resembles the letter delta (hence the name of the instrument). The model is ideal for grinding in corners and other places that are difficult to reach with oscillating, eccentric and especially belt sanders.

Due to the small size of the pad, they are designed for sanding small surfaces. For the deltoid model, you can purchase a spatula-shaped sole, suitable for cleaning old paints and varnishes, especially from chairs.

What to look for?

When choosing a deltoid model, you should analyze the amplitude of the oscillations (oscillation) - indicated in millimeters, it is 1-2 mm. The higher the value, the more the sole deflects, and the tool works more efficiently.

Model overview

Let's sum it up

When choosing which grinder is best, you need to analyze your own needs and compare them with the functions of the grinders. Different models are suitable for different jobs.

1. Draw machine extremely effective, quickly treats large surfaces. For example, it can quickly remove a thick layer of paint from wooden surfaces. The design is characterized by a high rated power. The machine is extremely easy to use and safe.
2. Random orbital sander– used for grinding flat, rounded surfaces. Has the highest accuracy. However, the sole does not reach hard-to-reach places and corners. The manual machine is equipped with a round disk that works in an oscillating and rotating motion at the same time, depending on the pressure. Easy to use, but requires a little more attention than oscillating. The instrument is held with both hands. Thanks to the combination of two movements of the plate, the model is efficient, fast, productive, and when used skillfully, does not leave visible grinding marks.
3. Oscillating sander used for large flat surfaces, perfectly smoothes the surface, the work depends on the thickness of the sandpaper. Optimal choice for beginners, easy to use, safe, does not require special attention.
4. Deltoid machine– small triangular sole makes it easier to work on surfaces that are inaccessible to large grinding machines. The small area of ​​the sole makes the model ineffective for processing large surfaces.

Sanding uneven surfaces is not an easy task. Previously, sandpaper was widely used as a grinding tool, but in our age of high technology, the sandpaper sanding method has become obsolete due to its low efficiency and labor intensity. Today, grinding machines, both belt and vibrating, come to the rescue in the difficult task of grinding. The variety of grinding machines is huge, so it makes sense to consider each type separately, and in this article we will talk about belt machines. We've found the most popular belt sanders and will help our readers figure out which belt sander is best for you.

The machine is equipped with a capacious dust collector, but it does not collect dust as well as we would like, so you should take care additional protection eye.

Unfortunately, the device is not suitable for work in industrial conditions, but for everyday household needs it is quite suitable; it is a good belt sander for wood. A 720W motor and a 75 mm wide belt are enough to process any wooden surface; the machine is also equipped with an additional belt tightening function, which is missing in many expensive models.

No. 4 - Caliber LShM-1000UE

Price - 3,200 rubles
A worthy option from a domestic manufacturer, an affordable and convenient grinding machine. This tool will serve as a good assistant for repairs; the tape is clearly fixed and does not slip during operation, although this device has a non-critical design flaw: The dust collector does not catch scraps well, so dust after work will have to be collected throughout the room. The 1 kW motor is sufficient for processing any surface; the belt speed is adjustable in the range from 120 to 360 m/m. The device comes with a handle with a lever for a comfortable grip, as well as 2 additional carbon brushes. The sander weighs 3.6 kg, the belt width is 76 mm, the machine is suitable for daily use, however, the belt gets very hot and the device requires short breaks to avoid overheating and rupture of the working part.

No. 3 - Interskol LShM-100/1200E

Price - 6,300 rubles


The top three is closed by another domestically produced product, the Interskol belt sander. Of all the models presented in the rating, this specimen has the most powerful motor (1200 W), so it can scrape laminate flooring, grind stone and level metal surfaces. The Interskol belt sander is best suited for long-term use in difficult conditions - it seems that even asphalt can be sanded with it, but with its weight of 5.6 kg this will not be an easy mission. The machine comes with a dust collector, which does its main task very well, but you still can’t do it without a protective mask and gloves. The machine can be converted for sharpening garden tools, the comfortable rubberized handle prevents it from slipping out of your hands, the belt is easily and quickly replaced, but for rare household needs it is wise to look for something simpler.

No. 2 - Skil 1215 LA

Price - 4,300 rubles
An interesting device, made in a futuristic design, but appearance is by no means the main thing of its advantages. The power of 650W is enough for repair work or use for small household purposes; such a tool is not suitable for industrial processing. The machine weighs 2.9 kg, the speed does not sag, the belt is automatically centered when the device is turned on. The productivity of the tape is limited to a threshold of 300 meters/min, which is more than enough for everyday use.

The machine is easy to assemble and disassemble, which may be necessary when the chassis becomes clogged with dust. With this machine, dust can be the only problem, since the size of the dust collector is not very impressive, and there is no way to control its filling. The machine's engine does not overheat even during long periods of operation, but it is recommended to pause occasionally to allow the abrasive belt to cool.

№1 - Black Decker KA 88

Price - 4,299 rubles

The leader of our rating was a grinding machine from the previously mentioned company, which outperformed other models in terms of price and quality and has impressive functionality. Externally, the unit resembles a vacuum cleaner without a hose, equipped with a comfortable rubberized semicircle handle with a comfortable grip. By the way, this machine not only resembles a vacuum cleaner in appearance, but also catches flying dust just as well, thanks to which the surface being treated remains clean. The device weighs a little more than 3.5 kg, which is acceptable for its size. The abrasive belt can be easily replaced with just one movement of a special handle, and the 720 W motor is enough to process medium-hard surfaces. Thanks to the reduced front roller, the machine can produce high-quality processing of both wide and narrow areas in hard-to-reach places, which is achieved using a 75 mm wide belt with a maximum travel speed of 250 m/minute.

The wood sander is widely used in industrial enterprises and in everyday life where processing is carried out various surfaces during the production process or during construction and renovation work.

Using such a compact device, craftsmen quickly and efficiently grind or polish floors and walls, restore dilapidated furniture and clean the surface of old paintwork.

Types of machines

Modern equipment with such functionality can be divided into several types according to the principle of operation and design features grinding units. When choosing a wood sander, you need to focus on its purpose, for which we suggest familiarizing yourself with the main types of equipment and its features.

Tape(LSM). The main purpose of belt sanders is rough processing of wood.. Depending on the interchangeable attachment, they can also be used for processing metal and plastic parts.

Vibrating. Such samples are used where it is necessary to carry out delicate grinding of the workpiece using circular movements of small amplitude. The working “sole” of the vibrating units is made in the shape of a rectangle specifically for processing corners. One of the varieties of such a device is a delta grinder, characterized by a triangular working element that provides for processing recesses and recesses, as well as hard-to-reach areas.

Eccentric (ESM) or orbital. This unit is capable of not only grinding, but also polishing, after which the material acquires a perfectly smooth surface. This effect is achieved due to the oscillatory-rotational movements of the device plate. However, it is worth noting that for small surfaces and internal corners such equipment will not work.

Features of application

Choosing a grinding machine for home use, make sure that this model is suitable for the intended procedures and can fully perform the assigned tasks.

Each type of sander has its own characteristics and recommendations for use, which we suggest you briefly familiarize yourself with.

Draw machines

Belt sanders are purchased by those who plan to remove an impressive layer of wood from a workpiece. Good in this segment electric tool represented by the Bosch and Makita brands, which are very popular among craftsmen. They perfectly process unplaned wood and remove old, thick layers of paint from carpentry. A belt sander will come in handy if you need to adjust furniture elements or sand the ends and cut points.

The operating principle of this type of machine is the effect of abrasive material on the workpiece. Thus, an sanding belt stretched on rollers along a ring moves at a given speed, removing a thick layer of material, just like an electric plane does. The thickness of the removed layer and the quality of work can be adjusted by the grain size of the tape and the number of revolutions of the working element, and the width of the abrasive affects the area processed in one pass.

In most cases, the presented brands of belt sanders are equipped with a standard belt 76x457, 76x533 or 76x610 mm, so it is convenient to process wooden material with their help various sizes, picking up best option emery. Semi-professional units can be equipped with abrasives over 100 mm wide, but home craftsmen are unlikely to need such equipment. Standard parameters rotation speeds for these machines vary from 150 to 500 m/min with a power of 400 to 1200 W.

When choosing belt-type grinders, give preference to samples with speed control and automatic centering of a tensioned abrasive made from zirconium or aluminum oxide. As practice shows, for more gentle work, choose aluminum oxide tape, such as shown in the photo.

Vibrating apparatus

The principle of operation of vibration technology for sanding wood is similar to the previous version. Here the process is performed with light oscillatory-rotational movements with an amplitude of up to 5 mm using regular sheets sandpaper. The type of sandpaper grit depends on the tasks at hand; this rule remains the same for all types of equipment. Abrasive material is fixed to the “sole” of the machine with Velcro or using a special clamp provided by the design of the unit.

By tradition, let’s turn to Bosch and Makita grinding machines, which are rightfully leaders in the carpentry market among similar devices. In addition to their main purpose, they remove corrosion from metal products without a trace, remove paint, remove plaster and putty material. By adjusting the amplitude level, you can choose the degree of grinding, from coarse to finer. Household versions of machines have a speed of 2000 - 5000 rpm, and their oscillation speed is within 2500 per minute.

The power of such units can range from 150 to 600 W, and when purchasing a tool, these parameters are among the most important. The higher the power rating of the grinding device, the longer you can work without interruption on such equipment, and its performance will also be significantly better.

Eccentric machine

Despite some similarity between orbital sanders and vibrating samples, it is worth noting their higher performance indicators. This machine allows you to get a perfectly polished surface without much effort. The working process here is carried out using a disk element with a diameter of up to 150 mm. Installed as an abrasive on eccentric units sanding wheels or felt attachments, indispensable for polishing procedures.

Even a beginner without experience can work on an eccentric unit with his own hands; the main thing is to correctly determine the optimal power on the device. Returning to the representatives of the Makita and Bosch families, we note that their power varies from 200 to 650 W at speeds of up to 13,000 per minute. As with any choice of grinding tool, in this case it is worth giving preference to machines with the ability to select the vibration amplitude and speed, which will make it easier to complete the tasks.

An orbital wood sander from the two leading manufacturers discussed above costs from 4,000 rubles, and its cost may vary depending on the technical characteristics and equipment. In order not to overpay in vain for unnecessary options, think in advance about what and how you will do with such a machine.

Homemade option

Sometimes the price of a factory tool makes you think about making a grinder yourself, especially if you need to do a one-time job on a small scale. Many craftsmen build a grinding machine from a familiar grinder, which, in principle, is an angle grinder, but some differences still exist. It is worth remembering that the grinder operates at high speeds, and it weighs a lot, so without experience and a “stuffed” hand, it can be difficult to handle. So that grinding with an angle grinder gives desired result, you need to be able to use attachments and polishing wheels specially designed for such purposes. Unlike a traditional grinder, a wood grinder has much lower speed and is inferior in weight.

If you are determined to convert an angle grinder into a grinding machine for processing floors or other surfaces, which will be in no way inferior to factory samples, you will have to modify electrical diagram original tool. Here you will need to additionally equip the angle grinder with a speed regulator, which helps reduce their number. You will also have to buy a set of special attachments, but this is a consumable item, and its purchase is relevant in any case.

Drill grinder

The characteristics of the grinding units make it possible to produce compact hand power tool from regular drill, for which it is equipped with an additional nozzle. Depending on the nature of the work performed, a drum or disc element can act as a working attachment. The support plate with a shank for clamping into the drill chuck is made of plastic or rubber, covered with sanding material. A part with a flexible shaft can be installed on a tool operating in manual mode, and if there is a rigid shaft, it is better to attach it to a securely fixed drill. If grinding is performed using abrasive drums, then the working surface of the grinding machine must be placed parallel to the axis of rotation.

As you can see, you can make a grinding machine with your own hands from a drill or grinder in a short time, without resorting to complex schemes and expensive components. Such a compact device is capable of processing wooden surfaces, polishing hard materials and removing old paintwork, which is necessary when performing construction and repair procedures, as well as restoring furniture.
