What is Bulgarian: species, characteristics. Watch what is "ush" in other dictionaries the correct name of the Bulgarian

Bulgarian is a corner electrical tool, with which you can cut metal, corner, stone, slate.

It is possible to carry out the grinding of welds or stripping rusty formations from the surface.

This power tool allows you to clean the wooden surfaces and cut the products from the ceramics.

We will figure it out why the ushum was so called, why are they used, what is the difference between one glorine model from another, depending on the class?

Why was the Bulgarian so called?

To begin with, it should be understood why the Bulgarian is called Bulgarian. Bulgarian is a corner-gland machine (USM), which serves for cutting both wooden and stone breeds and for grinding different surfaces. The name "Bulgarian" appeared in 1970 in the USSR. Then the Bulgarian factory, on which the corner grinding machines is now made, made the first tool samples. "Motherland" tool - Bulgaria, so it is called it. The "helper" people were appreciated by dignity, since then the name "Bulgarian" has consolidated for a useful tool and reached our time. Despite the pretty name, the angular grinding machine - Bulgarian - has a very tough, but loyal character!

Coroblipheal machines (EMS) offered on the market have many differences. What is the difference between one model of the grinder from another? This tool can be divided by the scope of application on the economic and industrial class.

For example, if classes are swapped in places, then in the economy to use industrial grinder will be very difficult due to weight, dimensions and power, you need to use another.

As for the industry, the light little Bulgarian will be more appropriate there, because it is a lot of heavy operations due to ease, low-power and limited functionality simply not to perform.

To select a universal electrical tool, it is necessary to determine the type of planned work. If they are large enough, the tool at a low price and with a small list of functions will not be unequivocally.

What are the difference in industry?

The appointment of the Bulgarian in the industry depends on its class, the difference between which is as follows:

Economy class

Inexpensive at the cost of grinders with limited equipment with important details and fixtures. Part of the models of this class does not have sufficient reliability and safety. The tool is well suited for rare and short-term work.

The housing of the cornering machine - the grinder - can withstand minor loads. Fastening although quite strong, but it does not always can guarantee convenience in work.

What is needed for? For household work, the instrument is not bad, but it is worth it in mind that the engine is not equipped with dustproof, in the process of work, small particles will fall inside and contribute to the acceleration of wear of moving parts. This will lead to the need to repair the tool. Metal dust causes short circuit.

For repair and construction work, more expensive and reliable Bulgarian ESM are used with high quality characteristics.

Middle class

This type of equipment is quite comfortable and safe to use.

It has sealing inserts and a paint coating of the engine, which does not allow the mud to penetrate the tool. Corner grinding machines (USM) are intended for household conditions, possess the clamping mechanism, providing speed control of the position of protection of protection.

The tool is equipped with convenient start buttons that respond even to pressing a finger in the rubber sleeve. The ability to screw the handle with any of the parties makes the use of such a tool convenient not only right-handers, but also left-handers.

In order for the tool to be comfortably used, certain models of grinding machines of Bulgarians support the installation of the handle from above.


Professional class

Professional tool very rarely requires the repair of a corner car - Bulgarian. Mechanisms are protected from dust effects, and the tool itself is equipped with a smooth start function, which allows you to gradually increase the speed of rotation and disk operation.

Grinding machine can be connected to a smaller power electrocups.

The tool of this class is equipped with a vibration protection due to the productive system of auto-battery working disk.

Criterias of choice

Usm Bulgarian needs to choose, paying attention to several criteria.

First: scope.

Second: number of handles.

Third: Elements of equipment are required to be rubberized.

Power and disk size

Bulgarians have different sizes and diameters of circles. The minimum size is equal to 115 mm. Such a circle is intended for simpler work. The largest size is the diameter of 230 mm. With this circle it is possible to cut brick, stoves, pipes and everything you need. The optimal choice of a circle for homework will be considered a diameter of 125 mm. To repair the house or apartment you need to choose a circle equal to 180 mm. The power of the tool varies from 0.5 to 2.5 kW.

The choice of such a parameter depends on the duration of the operation and power of the motor. For promotion, the engine must have enough power.

Additional options

Among the set of additional options, it is necessary to note the function of a smooth start. The system allows the tool to start without jerks, smoothing the voltage jumps that occur in the power grid.

You should pay attention to the presence of a disk auto-balance. The option is useful in cases where discs wear unevenly.

Smoothing and reduction of vibration occurs. The angular grinder of higher power is obliged to be protected from jamming. This feature avoids a negative situation and the consequences in which the electric motor can turn off automatically.

Conclusion

Do not forget that long-term and frequent overloads are capable of being caused by the breakdown and failure of the electrical appliance. When working, it is required to periodically make stops, which, in turn, will help not only eliminate and prevent overheating, but also to save the user from over-plane repair. Repair often can do quite expensive.

To purchase high-quality equipment, it is necessary to ask the seller the quality certificate of the device you get. Important will be the maintenance of the tool throughout the entire warranty period of use. Manufacturers who are not indifferent to the reputation of their company give a very long-term warranty to their own goods, which will protect the buyer from acquiring poor-quality and defective equipment.

Users who choose the instrument on the principle of price-quality, mark many positive sides from the Bulgarian, a good service life.

If you comply with all the rules, safety, working conditions, the equipment can serve faithfully and the truth is quite a long time. In the event of a breakdown after proper operation of the device, repairs can do it much cheaper, compared with the cost of repair with improper use of the device in unusable conditions or exploitation.

Bulgarian: what it is why it is called how to use the device scheme

Today, in everyday life, almost every home master has Bulgarian. Nevertheless, many do not know why it is so called, and what functions can perform this tool, in addition to conventional cutting. From this article, you will learn the origin of the unusual name of the Bulgarian, its device, and for what else can be applied.

How is the correctly called Bulgarian

All the usual name - Bulgarian - is so common that few people remember why it is called it. This tool is correctly called a corner machine (ESM). It was originally intended for the processing of inner angles at the joints of two planes. The first copies of such cars entered the Soviet Union from Bulgaria friendly, where they were produced. According to the characteristic people, the habit is a long and inconvenient name tried to cut. As a result, a new word - Bulgarian became firmly included. But on the package indicates the correct name - a corner machine.

Sometimes manufacturers use the SME option (corner grinding machine) or msh.

Gradually, they began to call all the power tools, externally similar to the prototype. Although the difference between them is available. For example, the grinder is often called the cutting machine.

The external similarity is undoubtedly present, but the cutting machine is equipped with a platform for the incision to be sent perpendicular to the treated surface than it differs from the grinder.

What can this tool

Classic Bulgarian is a manual power tool with an abrasive circle. The main purpose of the Bulgarian is the processing of joints of flat metal surfaces. However, it can be used for other operations. The main circle is perfect for cutting sheet metal, end trimming of pipes and reinforcement. A simple replacement of the working circle to a disk with sandpaper grinders turns into a polisher. Use a grinder in such an quality, processing pipes for railings, flat or twisted surfaces to a mirror glitter. In addition to the work on the metal, the grinder produces a cutting of ceramic tiles. To do this, you need to apply a circle on concrete as a work disk. The list of operations that can be done with the help of a grinder is very wide.

Each type of materials requires for its processing special disks:

  • grinding disk for metal with a thickness of 5-6 mm;
  • petal grinding disk;

  • cutting wheel on metal 2 mm thick;

  • cutting wheel in concrete and ceramics with diamond edge;

Device and principle of operation of the USM

The device of the angular grinding machine is quite complex. From which the USM consists, you can understand, looking at the drawing below.

The design of the machine can be divided into two parts:

  • electric;
  • mechanical.

The simplified electrical circuit of the ushm looks like this:

The head of the USM is a collector electric motor of alternating current. The supply voltage through the winding of the stator by means of coal brushes is supplied to the rotor collector (rotating part) of the electric motor. On the rotor are the windings section, the conclusions of which are located on the rotor anchor plate.

Cheap and low-power grinders rotate at a constant speed. More powerful models are equipped with a controller on the handle, which allows you to change the engine speed.

On both sides of the rotor shaft, bearings attached to the housing. This ensures the stable direction of the shaft during operation. The rotation of the electric motor is transmitted to the gearbox, changing the direction of rotation and the transmitting torque to the cutting circle.

The gearbox consists of two osospheric gears. Small hoping for the engine shaft, and large on the gearbox axis. For the outgoing outward part of the gearbox axis - the spindle is attached to the working tool (circle). Professional models are equipped with a delaying clutch - it stops the rotation of the working part of the tool, if for any reason the circle encounters in the material being processed. Without such a clutch, the circle disk can break and splits in different directions. A part of the surface of the circle is covered with a protective casing that protects the face and hands from flying from the cutting edge of sawdust and dust.

The working circle is attached to the spindle with a quick-release nut with a special key. The spindle immobility when tightening the nut is provided by the button on the side of the gearbox body, the opposite circle. There are longitudinal slot holes on the plastic housing. When working, it is impossible to close them, through them the electric motor is cooling.

Cellular machine. Cut and clean!

Almost any man uses an electric tool as needed - something to cut off, sublip, drill. One of the most popular electrical mechanisms for the performance of various works is a corner-lining machine (ABM).

Why is a corner car called a grinder?

The angular car in the commoner is also called the grinder. To understand where this name comes from, you need to dig a little in history.

In the Soviet Union, the word "Bulgarian" appeared in everyday life at the end of the sixties of the last century. At that distant time from us, the time of Bulgarians bought a license from Bosch to production of the ESM. Since the goods of capitalist countries in the USSR were not available, this tool appeared in the Fatherland, it was the Bulgarian production tool. Then Bulgaria was a country of the socialist community, and our trade relations with this state were well established. Therefore, in the USSR, the prevailing machines of this country appeared in the USSR, hence the name and name. The tool from Bulgaria began to call "Bulgarian".

Types of angular machinery and their appointment

USM is a tool required for construction or repair work. Such a tool is convenient to use when the material must be cut off, clean, poll. Of course, all these works can be done using hand tools, but then you have to spend a lot of time.

Bulgarian is considered a fairly universal tool, with the help of it you can perform various works:

  • Clean the welding seams;
  • Cut metal (for example, drainage tube);
  • Grind various surfaces;
  • Cut concrete or stone (with a special abrasive circle);
  • Work with ceramic tiles.

The scope of cutting machines wide, immediately all the works produced with its help will be difficult to list. The ushm for appointment is divided into two types: professional and domestic ones. Unlike domestic "Bulgarians", professional machines can work in a more severe mode, withsting long-term loads. True, it is worth such a tool more expensive - more quality materials are applied to its manufacture. The electric motor of the professional ESM is capable of working almost continuously for several hours, while not overheating.

Correffic machines and size differ. Large "Bulgarians" allow you to use cutting circles of a larger diameter, only a small disk can be installed on a small angular car. Each USM size has its own advantages when conducting certain works, and not always a large grinder will be convenient to use. A large tool is convenient to use when you need:

  • Make a deep propyl (for example, cut the pipe of a large diameter);
  • Cut a thick layer of material;
  • Treat solid material (concrete, stone).

Little "grinders" is convenient to perform various grinding and polishing work. First of all, the USM and was intended for this - no wonder in the title tool there is the word "grinding".

Characteristics of a corner car

The main characteristics are determined in which quality is best to use an angular grinding machine. You can allocate:

  • Disk rotation speed (number of revolutions);
  • Power;
  • Functionality;
  • Weight and size.

The speed of rotation is important in professional activities. With a small number of revolutions it is impossible to carry out some of the work, or the processing process will move slowly. Some types of work must be performed only on low disc speeds. Many inexpensive "Bulgarians" have only one speed. As a rule, it is rather high (about 10-11 thousand rpm).

The power of modern USM is ranging from 500 to 2800 watts. Power supply does not hurt, and is usually more powerful is a professional tool.

Weight and size are also considerable to carry out various works. Not always a large corner car conveniently use, despite the greater the power of the tool. For example, when scrolling the body parts of the car, the bulky ushm will be difficult to keep long, and it is inconvenient to use a large tool as a whole. And the machine small size will not be able to make a deep propyl, as it is impossible to install a large-sized cut disk.

Functionality is important for complicated work requiring special conditions. The additional functions of the ESM can be attributed:

  • The presence of revolutions;
  • The possibility of a smooth start;
  • Presence of an additional handle;
  • The presence of additional protection against vibration.

Parameters of cutting discs

Cutting discs (circles) are determined by two main parameters:

  1. Size
  2. Appointment by type of material.

There are five main diameters of cutting circles: 230, 180, 150, 125 and 115 mm, but professional discs may have a size of 300 mm or more. Accordingly, the circles of the larger diameter are suitable for large ears. More cutting discs have different thickness, and it can be from 1 to 4 mm.

Circles differ in their intended purpose - by type of material with which when working will have to deal. There are metal discs, stone, wood, reinforced concrete. The circles themselves can be made of different material and have a different shape.

Selection of a corner machine for home use

For work at home, there is no need to buy a large grinder - it is enough to purchase a tool designed to install the cutting disc from 115 to 150 mm. Since, low-size ESMs do not have very high power, then you should choose the most optimal model for this parameter. The best solution will be purchased a machine with a consumption of 1000-1200 watts.

It is better to choose a model of a tool with a regulator of the number of revolutions and a "smooth" start - a corner-glare machine will be launched smoothly, and on various revs it will be possible to process materials better. Attention should be paid to the convenience of the handle. Not bad if the handle will have antimony properties.

And one more important factor is the choice of the tool manufacturer. It is not worth buying a negligent machine of incomprehensible origin - everyone knows that the miser pays twice. There are many popular brands that have proven themselves only from the positive side. It is unlikely to be disappointed by the purchase of Metabo, Bosch, Dewalt, Makita. And, of course, you should not buy a tool with hands and used.

For what purposes is used by Bulgaria and why she got such a name

Sometimes during the repair process, including when laying the tile, it is necessary to cut some material. When cladding tiles, ordinary tiles may not cope with its task, for example, if it is necessary to make a curved cut. In this situation, an angular grinding machine is used, as the Bulgarian is correctly called. Consider in this article, why the ESM received such a strange name, as well as its device and main applications.

Why Bulgarian got such a name

So, consider why Bulgarian is called a grinder. In general, it is impossible to call it in this way. The term angular grinding machine is more suitable, which reveals the basic essence of the design and the use of this tool. The term "Bulgarian" for our ear is more accustomed, because some self-taped masters do not always know the correct name. I came to our use of this term in the 70s of the last century. It is determined by the fact that it was during this period that this tool appeared in the Soviet Union, and he was released in Bulgaria. The name "Bulgarian" is shorter and understandable to almost everyone, so it is unofficially distributed more.

Consideration of what can be done by a grinder

First, the Bulgarian is used where you need to cut something at an angle, for example, a pipe emerging from the wall. Also, with the help of it, it is possible to heat the strip in a sheet of material, where it is quite difficult to wheys in conventional hacksaw.

Secondly, Bulgarian is used when grinding various surfaces. For this, special nozzles are applied, which can be used in any construction store. It should be understood that Bulgarian is used for rough grinding of surfaces, since it remains semicircular traces from the nozzle. Thin thin grinding is performed using professional grinders.

Also on the grinder can be sharpening. Thus, you can prepare the ends of the pipes before cutting the thread or adjust it after cutting, so that the coupling or nut is checked easier.

Also, with the help of a grinder, the tile trimming is made before it laying. At the same time, the work should be made in a mask and glasses to protect against dust. Pruning is performed using a special cutting circle with diamond spraying. It should be remembered that with the help of a grinder you can make not only a straight cut, but also curved.

The main components of Bulgarian

At various manufacturers, the brandy device may vary, so we consider only the main components. This will make it possible to understand what to pay attention to when selecting this tool, as well as detect a malfunction in case of breakdown.

Main components:

  • bulgarian housing. It is performed from shockproof plastic and is designed to hold all elements connounced in it in their places. Also, with the help of the case, the operator's force is transmitted;
  • reducer. It consists of gears, with which the axis of rotation turns 90 degrees. Also gears allow you to reduce to the optimal number of revolutions;
  • electric motor. It is located in the tool housing and is designed to drive the lead gear of the gearbox, from which the torque is transmitted to the slave. On the axis of the large driven gear there is a disk;
  • electronics to which various smooth start systems can be attributed, start-up buttons, speed maintenance, etc.

Thus, we learned how the Bulgarian is called correctly, as well as for what purposes it is used and from which major nodes is.

Additional Information.

Today, in everyday life, almost every home master has Bulgarian. Nevertheless, many do not know why it is so called, and what functions can perform this tool, in addition to conventional cutting.

  • circle on the cutting tree;

  • chain circle on wood.

The device of the angular grinding machine is quite complex. From which the USM consists, you can understand, looking at the drawing below.

The design of the machine can be divided into two parts:

When working, it is impossible to close them, through them the electric motor is cooling.

  • cutting materials: virtually any fittings, galvanized profile, concrete, stone, tile, porcelain and much more.


Grinding, most often sufficiently coarse processing of welds, removal of rust and old coatings. But in the presence of rolver regulators and the corresponding snap-in is possible and red grinding and even polished.

Bulgarian is a tool that must be from any wizard.

And why the actual Bulgarian?

Of course there is a more complete and correct name, an angular grinding machine.

In mass production, he launched a German firm, well-known AEG well. Back in fortieth year. But before us, the news about such an instrument was given only in the seventies. On the expanses of the USSR, the power tools of the USM brought the Bulgarian manufacturer (Elprom Lovech). And others at that time were not, hence the "Bulgarian".

Choosing the power of the grinder, it must be remembered that the more powerful the tool, the more difficult and more difficult to work with it. Below we will look at the techniques of work, determine for what purposes do you plan to use the grinder and choose power and size accordingly.

Commandable types of ushm, diverse and assortment of replaceable nozzles, it can be:

  • disks
  • brushes
  • table tumble nozzles
  • circles for rough grinding and other

What are they used for?

Tarbed plastic tires (rubber) with fixed skurt are used for thin grinding.
Wire brushes are used for cleaning rust, old coatings (paints)

When choosing removable tools to the grinder, be sure to check the permissible speed of rotation. And if there is no revolutions adjustment on the ush, then some nozzles cannot be used (polishing circles) or even dangerous!

Cut circles, corundum or flint have a thickness of 2-3m and are used for cutting metals. For stone processing, tiles are used diamond cutting circles.

Bulgarians depending on the diameter of the drives used on: 115mm, 125mm, 150 and 230mm. Small sizes can cope quite easily and it is possible to keep when working even with one hand. But my advice to you, keep your two hands and use a protective cover. Bulgarian is a very dangerous tool and requires care when used. Antinoise headphones, if desired, but protective glasses are required!

Do not run on the EMS when working, cutting disc, the circle or other nozzle should not be treated. We will continue our move to skills.

Driving with Bulgarian Tool

Cutting metal, profiles, etc.

Install the cutting disk of the set size. The protective casing focuses so that the sparks and products of the cut are not flying to us.

In order to cut the metal moving the grinder "on itself", thereby send sparks in the opposite direction. We cut perpendicular to the disk do not give.

Cutting ceramic tile

Change the disc on a diamond circle for dry cut. If you need to cut a plurality of tiles in a straight line, then it is advisable to use the tiles or install the so-called sleds on the ESM cover. The cut is performed at a time, it is not necessary to cut the thickness. The tile will easily break a clear line of the outbreak.
With the help of a grinder you can cut rectangular cuts, roundings and even holes!

Stripping welding seams with a grinder

Esm-equipped with special circles (vindriate) are very comfortable for this. Circles usually have a thickness of 5-10mm. Use for these purposes cutting discs is extremely dangerous!

When processing seams, always use the side handle and hold the grinder with two hands. The tool is kept at an angle of 30-40 degrees to the surface. Since the circle will be emitted, respectively, will increase the working surface of the instrument, efficiency will increase. The rimpable circles are divided into types depending on the size of the ESM and Metal for processing. Reducing the angle up to the parallel to the surface is unacceptable, the disk becomes thin and can break!
Considering the seams do not hold the grinder in one place, otherwise the part and the circle will overheat.

If the USM has speed adjustment, then the maximum is used when sweeping seams. Strong pressure on the tool is also not required, the effect is 0, but the circle is very quickly flashed.

A special wire brush is installed on the instrument. The rotational speed is limited to 3000 rpm. The protective casing is better not to remove. Be sure to use glasses! Bulgarian holds with a slight tilt to the surface.

Bulgarian removes old coatings

And effectively, it is worth noting that it is absolutely an ideal surface. Extra grinding will be required.

Remove coatings with a circle of a plate-type with a grinding eye. Granularity from the middle to rude.
The protective casing can not be used, but the glasses are required! The working angle to the surface of about 30 degrees, in one place is not delayed, but we make smooth reciprocating movements.
Do not give the grinder, especially when removing paint, varnish, etc. with thin metal products. Excess pressure will result in the formation of brown, blue overheating spots. If this happened, you will have to make it very carefully to fade them. The tool is equipped with a fine-grained skin will help to quickly complain the cakes, but they will have to be done by hand or an eccentric machine.

Bulgarian cuts Shrobov


When cutting stone, concrete is formed a lot of dust, so it is better if the tool can be equipped with a nozzle for connecting to the vacuum cleaner. Use special diamond discs, including for cutting reinforced concrete. The depth of the cut depends on the power and type of grinder, the tool with a circle of 125 mm is designed to depth the cut of no more than 3.5 cm, but this is quite enough to make the stroke under the wiring.

How is Bulgarian correctly called? Having come to the store, you are unlikely to see a similar name.

Name and brief description

Among the many terms describing the tool, the corner grinding machine will be the most correct, or an ush. Most people consider metal cutting the main function of the corner mill. In fact, the grinding is suitable for other abrasive work with metal, tiles, stone, ceramics, wood. A huge selection of nozzles allows you to perform a huge range of works by just one "Bulgarian". What is worth one possibility of sharpening tools and rust removal from metal products.

Invention "Bulgarian"

Designing the world's first corner grinding machine began in Germany. In 1954, a tool appeared on one of the German factories that we were so accustomed to calling the Bulgarian. Grinding machines have passed a long way to come to modern ush. At first there was a machine working with a foot pedal. He did not resemble the modern "Bulgarian" by the appearance, but the functions were similar. Portable grinding, remotely resembling a huge ancestor appeared in the twentieth century. Further, the first manual grinding machine. Now its size was not so large, it became more convenient to work. And so, in the middle of the twentieth century, the first corner type machine appears, familiar almost to all of us.

The modern models of angular grinders differ significantly from the first inventions. Huge innovative potential possess the angular cars of the domestic producer of Interskol. Every year new features are invented, significantly facilitating work with the tool and improving security. Here and brushes with self-power, and revolt regulators.

Name history

The naming of the corner grinding machine "Bulgarian" appeared not so long ago, in the 1970s. Then, in the USSR there were many imported things from the countries of the neighboring countries, since they were much cheaper to buy them than to produce them. Cellvalifmashins, most of the Bulgaria, were called from Bulgaria. In addition, Bulgarians, coming to the USSR on earnings, brought with them this tool. In the commoner, the term "angular grinding machine" switched to a simpler "Bulgarian". So the tool continues to call these days.

Less well-known names

In addition to the "Bulgarian", the tool had a few more interesting nicknames:

  • "Fortune"

One of the first models of the USM, which appeared on the territory of the USSR, was called "Fortune". She immediately acquired enormous fame because of its convenience and multifunctionality. On the hearing of migrants, which brought such grinders to the country, she was not called the "fortune". So this name has been fixed.

  • "Monkey"

This nickname is little used in everyday life, it appeared due to the joke. Among the workers went the legend that hands were lengthened from work with such a tool. As a result, they become similar to the limbs of monkeys. The joke got the spread among people, and Celloshlifmashina became a "monkey". So it is a humorous name and entrenched in the people.

  • "Turbine"

Another humorous name. The point in the corner grinding machines during their work has published a sound similar to the sound turbine. Passing by the factories, where they worked as grinders, it was possible to think that the workers are preparing a plane to take off. In the shops of the Soviet Space, the ESM has become a "turbine". This name is not very popular, but still you can hear it.

  • "Flexi"

This name is rarely heard in Russian-speaking countries, but in Europe almost everyone will understand what kind of tool you are talking about. This name appeared for a very long time, about the 1930s. The first grinding tools began to be made in Germany. In about the 30s, the MS-6-Flexen model - manual grinding machine appeared there in the 30s of the twentieth century. The nickname "Flexi" fastened for this model of the instrument. With the appearance in the 50s of the first corner grinding machines, the term switched on them. The model is gone, and the "nickname" remains.

Surprisingly, the same tool has many nicknames and titles. His abundance of nicknamed a corner-glare machine is obliged to the people. People from different cities can talk about one tool, but call it differently. Thanks to this article, you can avoid misunderstanding.
