Sanding is one of the types of body work. Given the large surface area of ​​the body, doing them manually is inefficient, therefore, labor automation is required. This article discusses how to choose a grinding machine.

Two classes of sanders

The choice of the device in question should be based primarily on its purpose. That is, you need to decide what the machine is needed for and what kind would be better suited. At the same time, they take into account what work is planned to be performed with its use and how long to use it. Based on these parameters, they choose between professional and household models.

Professional instrument

The main difference between these types is that the first grinders are designed for long, continuous operation in difficult conditions. Their high reliability and durability are due to the fact that high-quality materials are used in the production of such models. In addition, they are characterized by high power. This leads to the large mass and high cost of such instruments. Spare parts for a professional type sander include rollers, abrasive belts and attachments, bushings, running parts and other elements.

Household devices

The main advantage of such options is cost. Although among them there are quite high-performance devices, their capabilities are still inferior to the characteristics of professional analogues. However, for the needs of ordinary users this should be sufficient. For rare work, it is not advisable to purchase an expensive and complex device. However, it must be borne in mind that such grinders can operate for approximately 20 minutes, after which a break of the same duration is required. Moreover, you can rent a tool to perform one-time work.

What to consider when choosing?

The choice of tool design is carried out based on the characteristics of the work. This takes into account the type of material and surface. The easiest surface to process is a flat one. Before choosing, you should look at reviews, video reviews, manufacturer ratings and model ratings. They can tell you a lot about specific instrument models. Moreover, both quality and popularity ratings are useful.

You also need to consider not only how much the tool itself costs, but also the cost of components and spare parts for grinding machines. The maintenance price includes abrasive items, such as sandpaper for a sander. Such equipment is used by a flat machine; other options require discs and brushes.

Classification

There are several types grinding machines, allocated on the basis of design.

Corner

Grinders of this design are the most widely used. They are called Bulgarians. The popularity of such models is explained by the fact that these grinders are universal. They are suitable not only for polishing and grinding surfaces made of various materials, but also for cutting and processing metal and stone.

When choosing such tools, you need to focus, first of all, on the power and diameter of the disk. Simple options have a power of 600 - 1000 W, providing rotation speeds of up to 6000 rpm. They can be used for grinding, polishing and shallow cutting. Jobs such as cutting stone will require grinders with a power of around 2000 watts at the same blade speed.

The diameter of the circle is also important, but manufacturers produce devices for standard sizes of abrasive elements, which simplifies the choice. They range from 115 to 230 mm. There are also two options for the diameter of the mounting holes: 22 and 32 mm.

In addition, you should choose a grinding machine with variable speed control, since devices that do not have this device are not capable of performing all types of grinding, but are suitable for cutting various hard materials.

Direct

Such tools are used for small jobs that require high precision. For example, they are used for grinding small surfaces such as lintels and planks, as well as edges and corners. In addition, using specialized attachments that are equipped with most grinding machines of this type, you can cut various materials of small thickness and apply engraving.

Many straight grinders are lightweight and designed to be held with one hand. Another important design feature of the tools of this type is the location of the spindle parallel to the body.

Tape

The main purpose of such tools is primary surface treatment large area. Thus, they are used for rough grinding, leveling, stripping, and removal of paintwork. Belt grinders are most in demand by professionals, although there are also household options.

The abrasive working element of grinding machines of this type is represented by a sandpaper tape glued into a ring. Most tools are equipped with a belt width of 40 - 120 mm, although there are options less than 40 mm wide, designed for processing difficult surfaces. In any case, the working element rotates on two end rollers. You can learn more about the operating principle of such tools from the video. Outwardly, they resemble an electric plane.

Large flat working surface Belt type sanders provide the highest productivity. However, the quality of work is low.

The main parameters of such devices are the speed of the belt, the presence of a dust collector and a soft start system.

Vibrating

Such machines are also called surface grinders. The flat model is used for final pre-painting treatment of surfaces, as well as for removing paint deposits before re-painting. In addition, the flat grinder is suitable for processing materials such as wood, metal, stone, plastic, and composite materials.

A flat sander operates on the basis that the flat sole performs reciprocating movements of high speed and small amplitude. You can clearly see how the flat machine works in the video.

The main parameters that characterize the flat model are the power and amplitude of oscillations.

Eccentric (planetary, orbital)

Grinders of this type are universal, that is, they have a wide range of applications. Thus, they are used for grinding, cleaning, polishing surfaces made of metal, plastic, wood, as well as for fine grinding. In addition, they are suitable for processing curved-convex curved surfaces.

The principle of operation of eccentric tools is that the working surface performs rotational and oscillatory movements. You can see how a circular machine functions in many videos. The main parameters of the devices under consideration are the oscillation amplitude and power.

Brush

The name of this type of grinding machine is due to the fact that the abrasive element is represented by a metal brush. There are direct one-handed versions of small size, as well as models bigger size, similar to belt sanders, with two metal brush rollers. They are convenient to use as a glass grinder.

Delta

This equipment is used for processing small parts and hard-to-reach places. According to the principle of operation, these devices are similar to vibrating tools and differ from them in having a forward sole, similar in shape to the working surface of an iron, and in smaller sizes.

Polishing

Such grinders are mainly used for polishing metal. In addition, they can function with cutting discs. In design, these devices are very similar to corner ones.

Multifunctional

Multifunctional grinders combine vibration, polishing and delta grinders in a housing. They find wide application in repair and finishing works Oh. Multifunctional sanders are versatile due to the ability to replace attachments.

Rotary

This equipment is mainly used for grinding and polishing stone. The principle of their operation is to rotate the abrasive element around vertical axis, which can be seen on video. For different jobs, the rotary machine can be equipped with different circles.

End

Face grinders are mainly used for finishing work. This is explained by the fact that end grinders are well suited for grinding and polishing surfaces made of materials such as metal, granite, and marble. Face grinders are designed to be held with two hands.

Typically, the rotation speed of their working element is 5000 rpm, due to which face grinders provide good processing quality.

Special mention should be made of glass grinding machines. Used in production specialized machines. At home, even a drill equipped with special attachments can serve as a glass grinder.

Have you bought an apartment with a mortgage and don’t have an extra penny at hand? Then you can save on repairs. Those who are making repairs with their own hands for the first time need not be afraid: experience comes with time and the amount of work done. Not everyone manages to please their demanding family the first time, especially in young families with a demanding young mistress. You have to work hard. However, time passes, and you are already at the stage of finishing work. This is where the need for sanding or polishing arises. You may have to saw off a piece of the bathroom pipe to fit it. All this is not scary if you arm yourself with minimal knowledge about grinding machines, working with which is not so difficult if you judiciously choose a grinder (or grinder, as it is often called) with the desired function. What types of grinding machines are there?

Grinding removes dirt from the floor surface.

Belt sanders

This type of tool is necessary for those who are going to grind large areas of flat surfaces. You can also purchase such a machine if you need to remove a thick layer of putty, varnish, or simply treat a rough surface. A similar sander is used for working on wood, plastic or even metal. The design of the tool provides a convenient placement of the center of gravity, which reduces the load on the hands. If you need to prepare edges and bevels in workpieces, then you can safely purchase a belt sander.

Most models of belt sanders can be installed permanently.

The main working element of the machine is the sanding belt, which rotates along guide rollers. The operating principle of the machine is reminiscent of the operation of a caterpillar tractor. Such a tool can operate at a speed of 70–500 rpm and consume power from 500 to 1200 W. In stores, you can choose a model in which the speed of the sanding blade can be adjusted (the speed can be smooth or stepped). It makes sense to purchase a model with an additional handle for processing corners. If you value convenience, then instead of a respirator, get a sander with a dust collector. In order to prevent deformation of the part, a grinding frame is used; The vice will allow you to use the grinder in a stationary mode. If you need to accurately machine parallel surfaces, then you should choose devices such as angular and parallel stops.

Fastenings allow you to easily remove the old and install a new tape, which, thanks to quality manufacturing, does not fall off the guide rollers. Some models of belt sanders have an automatic belt centering system; it is also possible to use narrow and wide sanding belts. If it is necessary to carry out work on rough peeling of the surface, it makes sense to choose a tape with a large grain.

The belts, both for light sanding and for complex abrasions, are made of durable fabric and are not afraid of heavy loads.

The following types of machines need to be highlighted:

• belt file - it is used to penetrate into places that are difficult to reach for an ordinary grinder;
• brush sander – allows you to process the surface using a special brush (suitable for wood and metal). It is used by those who need to remove rust, paint or another type of synthetic coating.

Vibration option

If the sandpaper is attached to the pad with spring-loaded clamps, you can use paper you cut yourself.

In most cases, such a machine is used for finishing when working with various materials. Surface treatment is carried out using vibration of the sanding plate of the machine itself. The vibrating force is generated by rotating an eccentric motor mounted on a shaft. If you need to process a large area (for example, parquet throughout an apartment or house), then an orbital sander with a rectangular plate will successfully help you cope with this. The power of the vibration grinder is 160 – 600 W. The engine speed control on some models reaches 20,000 rpm, which is very attractive for use on almost any surface.

Vibrating sanders may be equipped with a dust removal system into a special container or may discharge dust into a running vacuum cleaner through a slot in the sanding sheet itself. This increases the comfort of use and extends the life of the sanding sheets.

How are sanding sheets secured? This is possible in two ways: using clamping levers (which is more practical) or using Velcro (in some cases this is the optimal solution). Some advanced models have a replaceable sanding plate, thanks to which the sanding sheet can be secured different types fastenings. Sanding sheets for orbital sanders have different grain sizes, which allows them to be used in different situations.

Delta sanders

Delta sanders are ideal for sanding corners.

If you decide to do restoration old furniture, window frames or blinds plates, then such a machine will become yours an indispensable assistant. The operating principle of a delta grinder is similar to vibrating models of grinding machines, however, the special shape of their grinding plate makes it possible to process surfaces in narrow and hard-to-reach places. The power consumption of such a tool is only 100 - 300 W. Dust is removed into a special container. If you decide to choose a delta sander, please note that the sanding sheet is attached only with Velcro. To save money, some manufacturers have developed models that allow you to rotate the sanding sheet in the desired direction and use its surface to achieve maximum abrasion.

For delta sanders, you can purchase additional sanding or cleaning cloth to clean metal surfaces from rust, process hard-to-reach wooden parts, and matt varnish coatings. Polishing sheets will allow you to correctly carry out finishing, polishing and rubbing.

The supplied plate nozzles will allow the master to easily penetrate the narrowest crevices. If someone has once used a sanding plate with a flat or oval tongue, he will easily take on the processing of concave or rounded parts.

Random orbital sanders

Thanks to the complex trajectory of movement, you will never walk through the same place twice.

The operating principle is similar to vibrating grinders. The difference is the ability to perform not only reciprocating movements, but also circular ones. This property allows you to increase the productivity and range of use of the machine, which helps to carry out grinding work on convex and concave surfaces without risks. A special advantage of some eccentric sanders is the presence of an elastic sanding pad.

The motor power of the eccentric grinder is 150 – 400 W. If we choose a model with adjustable engine speed, the speed of final processing will increase accordingly required part. Dust from such a machine is removed into a container through a hole in the sanding sheet. For those who are partial to electronics, there is an electronic system for setting engine speed.

A good selection of sanding sheets with different grits help you work with a variety of materials. Wool caps and polishing sponges allow for high-gloss polishing of particularly thin surfaces. The main method of attaching polishing sheets is Velcro.

Angular analogue

It is the grinder that has been the most common tool for quite a long time, capable of processing stone and metal, grinding, peeling and cleaning almost any surface. If you’re going to choose a grinder for home use, then, of course, a grinder. However, we must not forget that the working disk of an angle grinder is designed for processing a certain type of material. Do not cut with a wheel that is intended for grinding, and vice versa. Otherwise, you will be injured. If you decide to make a deep cut, then you need to select a disc of the appropriate size.

Working circles are not included in the standard package.

You can replace the disc on an angle grinder using a wrench or a special nut, which you can tighten by hand.

Angle grinders can be single-handed or two-handed. Both are equipped with an additional handle, allowing you to work in more comfortable conditions. If it is necessary to cut stone, then special guide slides should be used. Professional models of grinders are equipped with systems for adjusting and maintaining the speed, smooth starting, protecting the tool from switching, and automatic balancing of the disk. To protect the craftsman, angle grinders are equipped with protective adjustable covers and are provided with a special button that blocks accidental activation of the tool.

If you decide to purchase a sanding machine (which wouldn’t hurt even for a small household), then figure out how often and for what purposes you will need it and what material you will be processing.

Don't forget to pay attention to the following parameters:

When choosing a tool, be sure to find out the availability of consumables.

1. Tool power. The productivity of your work depends on it. If you're not going to go beyond repair work within the apartment, then select a machine with a power of 0.7 - 1.0 kW. If your plans include concrete work or just frequent grinding work, take a closer look at machines with a power of 1.5 kW or more.
2. Number of disk revolutions. Discs of different models rotate from 2700 to 11,000 rpm. The smaller the disk, the higher the speed and vice versa. Exceeding the speed is fraught with fracture of the workpiece and injury to the technician.
3. Disc (circle) diameter – Depends on the thickness of the material being processed. If you need to use a large disk, then you need to choose a more powerful model for it. Today, models with a 125 mm disc are popular, allowing them to satisfy the most basic household needs.
4. Smooth start tool - allows you to avoid sudden load on the electrical network. A smooth start will help to avoid sudden jerks when turning on the tool, which, in turn, reduces the risk of breakage of the workpiece and injury to the technician.
5. Ergonomics of the tool. The ease of use of the tool (for example, the presence of a flat body allows you to use the machine in tight spaces), its weight, and the presence of an anti-vibration handle contribute to comfortable and enjoyable work.
6. Quick-release protective cover - allows you to install yourself in the desired position without the use of additional tools.

Whatever machine you choose, do not forget about work safety. Take the time to wear gloves and safety glasses. Make sure your baby is under the supervision of a caring mother and does not risk getting an electric shock. Then any repair work will bring joy and satisfaction. After all, what is done is done with your own hands.

To make a choice, you need to clearly understand the purpose of each type of grinder. At first glance, the operating principle of grinding machines is the same - grinding the surface of a material using abrasive equipment. In each specific task One type of sander will perform brilliantly, while another will not give the expected result. For example, eccentric machines cannot process internal corners, but vibrating sanders can do this. Let's look at the types of grinding machines and determine the scope of application of each of them.

General Features

• Most modern grinders are equipped with a dust removal system: it is connected through a special pipe or comes with a dust collection bag. This makes the work process cleaner, the tool itself is better controlled, and the consumption of abrasive equipment is reduced.
• Based on the type of power supply, machines are divided into mains-powered and battery-powered. The advantages and disadvantages of cordless sanders are obvious - mobility and independence from the mains, but operating time is limited by battery charge.

Random orbital sanders are considered the most effective and versatile tool for polishing and grinding surfaces. IN industrial production and in private use they show the most best result on the quality of surface treatment.

Polishing and grinding are possible thanks to a combination of rotational and eccentric movements of the soleplate. The sole rotates in orbit and simultaneously scrolls around its axis. This complex movement of the abrasive allows for efficient grinding with minimal imperfections.

The machine weighs from 1 to 3 kg, is equipped with a round sole with Velcro, to which it is attached. The soles come in two sizes - diameter: 125 and 150 mm. Machines with a 125 mm soleplate are lighter, designed for smaller areas and for more delicate work than sanders with a 150 mm soleplate. Electric motors consume from 200 to 900 W - more power provides more performance.
When installing the equipment, it is important that the holes on the sander sole coincide with the holes in the abrasive wheel, otherwise the dust removal process will be difficult.

They are used for rough or fine grinding on large surfaces, for interlayer processing of materials and coatings, for polishing, processing large surfaces along and across the grain. Often machines of this type are used in carpentry and car painters. Using ESM, volumetric, profile and curved surfaces are processed. When working with an eccentric sander, it is unlikely to damage the workpiece: make abrasions, burn the material, or overdo it with the grinding depth. The noise and vibration levels are lower than other types of grinding machines.

The disadvantages are obvious: eccentric machines are not suitable for processing internal corners and recesses. Productivity is low compared to belt sanders.

These machines weigh from 1 to 3 kg and are equipped with a rectangular sole with a clamping mechanism at the edges that secures the sanding paper. There are models with the ability to fix the equipment to the sole using Velcro.

The sole makes reciprocating movements in a circular orbit, due to this grinding or polishing is carried out. The power of the electric motor of this tool is from 150 to 600 W. There are two types of soles: standard- 100 X 200 mm, and mini- miniature versions with a base of about 100 X 100 mm.

It's easy to make a choice here: mini Surface grinders are suitable for bottlenecks, they are lighter and more maneuverable standard.

Designed for delicate processing of large flat surfaces. They occupy an intermediate place in terms of the cleanliness of processing parts between belt and eccentric ones. Finish sanding is carried out using a surface grinder. different surfaces: wood, plastic, stone.

Advantages: the ability to grind and polish internal corners, availability of consumables and moderate cost of the grinder itself.

Disadvantages: high noise relative to orbital ones.

The peculiarity of this tool is its compact, lightweight body - tool weight up to 1 kg; delta-shaped sanding pad, which is why these machines are called “iron”. Electric motor power up to 300 W.
Grinding in hard-to-reach places is carried out due to the fact that the triangular sole makes rapid vibrations with a small amplitude. This tool is not sold everywhere and is more expensive than a sanding belt. paper based or grinding wheels.

Using a delta sander, fine grinding of protrusions, blind corners, edges, profiles, cleaning of exposed glue, processing of objects with small parts and complex surfaces are performed.

The delta-shaped orbital sander is especially good in carpentry, furniture making, stairs, and automotive body work; it is used as a main tool or in addition to eccentric or orbital sanders.

In belt sanders, the equipment, glued together in the form of an endless ring, moves in one direction along two end rollers, one driving, the other rotating freely. Linear grinding and high abrasive speed provide high productivity, but at the same time require increased control over the grinding process. Blade blades weigh up to 7 kg, and the electric motor power varies from 500 to 1500 W.

The three main standards of belt sanders are distinguished by the length of the sanding belt: 457 mm, 533 mm, 610 mm.

Belt sanders are suitable for rough grinding of surfaces made of wood, metal, plastic, mineral building materials. Often used when removing old paint or varnish, leveling putty. Due to its high productivity, a large amount of material is quickly removed, and in combination with coarse-grained abrasive, the belt sander can perform the function of an electric planer. The quality of grinding is not the best indicator of this tool; cavities and scratches often appear during processing. Effective for sanding glued panels and processing convex-shaped parts. There are models with the ability to work upside down, stationary.

This tool is not suitable for delicate grinding and requires special control when working. It can leave indentations in the material and, due to the specific nature of the sole, belt sanders do not sand enough in the corners. High level noise and frequent clogging of the dust drain are the disadvantages of this tool.

Electric file

There are belt sanders special purpose, the so-called or. Often used for cleaning welds and grinding materials in hard-to-reach places.
Only certain equipment with a width of 9 to 30 mm is suitable for electric files.
Such belt sanders weigh much lighter than conventional ones - 1-2 kg.

Making a choice

• You need to quickly clean a large surface without special quality requirements, remove a large amount of material, choose.
• Requires constant processing small parts or grind different angles, choose .
• We need a universal tool for grinding a large number of different materials, choose.
• If the tool must be universal, but there are high demands on the quality of grinding, we choose.

Having decided on the task and type, we make a choice in favor of a specific model of grinding machine.
If you have to work with the tool in weight, with outstretched arms, you need to pay attention to the dimensions and weight of the grinder. It is better to make a choice in favor of a light, compact, faster machine, albeit less powerful. If the work will mainly be done on a workbench, choose a machine with more weight and more power.
It won’t hurt to turn the machine in your hands before buying, to understand how comfortable the handles are for you, whether the switches are conveniently located, how quickly and easily the equipment can be changed. Check the moving parts for play, visually inspect the body of the machine, look at the accuracy of the fit of the parts. Turn it on at least Idling to assess noise and vibration levels. Inquire in advance about the availability and cost of consumables and equipment, such as spare soles.

Watch the video and make your choice

Wood, as one of the most popular and convenient finishing materials, does not cause any particular difficulties in processing.

But to achieve a perfectly smooth surface, for example, under varnish, ordinary carpentry tools will not work. A wood sander can speed up and facilitate leveling.

This multifunctional device is presented on the market in various modifications, differing in design and application features.

Types of cars

There are several main types of sanders for household use on sale. Each grinding machine has its own design features and mechanism of action.

For carpentry, joinery, construction and repair work, the following types of power tools are chosen:

• belt sander for wood (LSM) designed for rough and aggressive processing of surfaces, including plastic and metal;
• brush sanders allow you to highlight the wood texture by removing more soft fibers, remove layers of varnish and old paint. The working part is a roller on which a metal or abrasive nylon brush is mounted;
• Vibratory grinder (VShM) used for a softer finish. Gentle processing occurs due to circular movements and the small amplitude of the working tool. The sole has a rectangular shape, which makes cleaning corners easier;
• delta sander- a type of flat vibratory sander with a triangular-shaped sole. This device is suitable for treating hard-to-reach places and small areas, as well as recesses, corners, irregularities;
• eccentric sander– a power tool that allows you to bring the surface being treated to an ideal state, including plywood. This task is accomplished through the rotational and oscillatory movements of the sanding pad. The device has a high degree of productivity, but cannot be used for cleaning internal corners and small surfaces.

A wood sander is an indispensable tool for processing walls, floors, interior items and other decorative elements. It can speed up the process of grinding and polishing surfaces made of natural materials several times.

Angle grinder capabilities, discs for it

A grinder (angle grinder) can also be used for sanding wood. It can be used for rough processing.

This tool allows you to quickly clean wooden surfaces, in particular sand floors and walls. This versatile device is capable of performing the most different operations, and for each there are appropriate wheels: cutting, grinding and roughing (grinding).

A grinder can cut metal, stone, and wood. But it is not advisable to saw boards and other wood, otherwise the tool will overheat greatly. Saw blades reminiscent of wood for an angle grinder modern models saws, but other alloys are used for their manufacture. The only drawback of an angle grinder is the presence of various irregularities after work, which then take a long time to level out.

For grinding work, special red wheels are used. A good option– use of petal or disc wheels with a grain size suitable for each case.

Considering that the working plane is located under the protective casing, performing specific actions does not pose a danger to humans, which makes it possible to move the tool in any direction. The main thing is to be careful when working with surfaces that have protruding heads of screws and nails.

Note! To make it easier and faster to replace sandpaper, it is recommended to install an attachment with a sticky surface on the grinder.

Draw machine

In a belt sander for wood, the working element is represented by a belt fixed around two rollers. During their movement, the tape attached to the sole is brought into working condition and rotates at the required speed. It is the speed that is considered an important indicator of the operation of this device and it depends on the power, which can be in the range of 500-1200 W. There are tools equipped with an additional speed regulator, which allows you to select the most suitable best option for every type of surface.

Belt sizes vary depending on the modification of the sanding machine. This indicator is the highest for the most functional device. At the same time, the weight and dimensions of the structure will also be significant. Special attention When choosing a power tool, you need to pay attention to the grain of the tape used. For ease of work, it is necessary to have several types of tapes with different grain sizes. One type of belt sander for wood is a brush device that performs the roughest processing.

Orbital (eccentric) sander

According to the principle of operation, this device for processing wooden surfaces is similar to a VShM. The main distinguishing indicator is the higher productivity of the vibratory sander. In addition, processing is carried out more accurately and delicately thanks to the complex trajectory of the grinding element. The grinding is carried out with discs with a diameter of 15 cm. Abrasive circles of suitable grain size are molded onto them.

The disadvantage of an eccentric machine is the formation of excessive amounts of dust. But manufacturers supply models equipped with effective dust collectors, which allow work to be carried out in enclosed spaces.

Vibrating sander

Sole technique vibration type can be triangular (iron) or rectangular. During processing, she performs circular movements with a small amplitude. The machine is used for those cases when it is necessary to obtain a high-quality surface, for example, to restore furniture before applying stain or varnish. Sanding is required especially carefully, since through the transparent layer finishing coating All flaws will be clearly visible. At the same time, the device has low performance.

Note! It is better to choose a rectangular sole for finishing large areas, and for corners and hard-to-reach places it is advisable to use a triangular shape.

When working with a vibrating sander, be sure to remove debris, any solids, grains of sand so that small circles - marks - do not form on the surface. To remove such defects, you will need an abrasive wheel with the finest grain size. The surface of the wood to be treated must be thoroughly cleaned with a vacuum cleaner.

Oscillating wood sander

This electric tool is a multi-functional renovator that is also capable of sanding wooden surfaces. It is different from other tools budget price and very low power consumption. It can be used to treat sharp corners and areas close to vertical walls. To carry out this manipulation, a special triangular platform is installed on the grinding machine, to which a grinding wheel on a self-adhesive base is attached. In addition, the device makes it possible to effectively clean the floor from glued linoleum and tiles, create slots, and cut communication lines.

During operation, the sole moves in horizontal plane with minimal amplitude, the tops of the platform deviate by an average of 2.5 mm (1.7 degrees). Due to these movements, surface treatment is carried out. This device can be used for grinding corners and other hard-to-reach areas. The machine does an excellent job not only of removing wood, but also of smeared or dried glue. In general, the oscillating machine is used for finishing in places where other machines cannot cope due to their low productivity or sanding spot.

Criterias of choice

When purchasing a specific model of grinding equipment, you should take into account the tasks that the power tool must perform in the future. The choice of professional or household equipment depends on this.

Professional wood sanders are ideal for long, active and continuous work. They will cost much more than household tools. For use without significant loads and long-term work, you should give preference to simpler grinders. If the choice is between professional device and ordinary ones, it is better to purchase the first option, despite its high cost. If the second one was chosen, then when working with it it is recommended to subject the device to less heavy loads. You need to pause every 3 hours. Only following simple operating rules will extend the life of the tool.

It is also important to consider the type of work for which the grinder is selected. For processing smooth surfaces, the optimal solution would be to purchase a belt sander. If there is a need for grinding or polishing decorative wooden products, then it is recommended to purchase eccentric models. The ratio of the cost of consumables and upcoming costs during operation of the device also needs to be taken into account.

If you intend to use the grinder in indoors, then you should pay attention to equipment with a built-in dust collector or the ability to connect a vacuum cleaner. Considering that the process of sanding surfaces will generate a lot of dust, you need to prepare for it to appear everywhere. Cleaning the premises manually takes a lot of effort and time.

The length of the cord plays a role when choosing a sander model. significant role. Since it is inconvenient to work with a device on a short cord, and it is not always possible to use an extension cord.

We sell battery-powered tools that are useful for work in the country and in houses where electricity has not yet been installed. The cost of such models is high.

When choosing a device, you should test the location of the handles, check whether it is convenient to switch modes, and how difficult it is to hold the machine in your hands.

Manufacturers and models

Among the most popular factory devices, characterized by a high degree of reliability, are the following grinding machines:

• Makita 9924 DB. The device has a power of 850 W, a speed of 210-400 m/min and a weight of 4.5 kg. Price 15930 rub.;
• Bosch GBS 75 AE. The grinding equipment has a power of 750 W, a speed of 200-330 m/min and weighs 3.4 kg. Price 15050 rub.;
• Sparky MBS 976. The model is produced with a power of 900 W, a speed of 160-340 m/min, and a weight of 3.4 kg. Price 6582 rub.;
• AEG BBSE 1100. Main operating parameters: power 1010 W, speed 230-400 m/min, weight 5 kg. Price 15,470 rubles;
• Skil 7640 MA. The device has a power of 950 W, a speed of 340 m/min and a weight of 3.6 kg. Price 6100 rub.

Of course, there are a large number of other models of sanding machines. The Interskol and Zubr brands are in demand; Hitachi, KRESS, and DeWalt products are worthy of attention. The price range is very wide and depends not only on the manufacturer, but also on the region of sale. Some DIY enthusiasts make homemade grinders using old broken equipment, drills, and hard drives. In terms of performance, such devices are unlikely to compare with factory tools, but they will save money.

A grinding machine can greatly make the life of a home craftsman easier. With its help you can easily remove old paintwork, rust, wipe off a layer of putty and so on. The grinding process itself is a rather monotonous and labor-intensive operation associated with a large amount of dust, so doing such work manually is quite problematic.
