How to install a brush on a grinder. Replacement methods

How to connect brushes to a bison grinder

The design of the grinder, the source of energy of which is an electric current, is able to convert it into a mechanical. The interaction of all nodes of the grinder is shown in the fundamental diagram of connecting its electric drive.

After the power cord is connected to the outlet and the launch is turned on, the electric current is supplied to one of the brushes.
After passing through the collector winding, the current appears on another brush through which stationary windings of the stator are ensured by the power supply.
The magnetic fields created by the Windows of the stator and rotor interact with each other, causing rotation of the rotor fixed in the bearings. Together with him, the torque arises on a conical gear set to anchor. Another conical gear, paired with the first, rotates a spindle with a working tool of a grinder.
Additional taps of stator or rotor windings allow you to increase the functionality of the power tool by creating various control systems.
Signals are transmitted through the contacts of the collector plates about the rotor rotation speed to the tachogenerator or hall sensor. With their help, the necessary revolutions of the grinder are maintained.
To protect the grinder from overheating, the heat protection unit applies. It turns off the tool if the sensor shows the maximum permissible temperature of the control surface of the grinder.

Understanding the role of each of the elements included in the electrical scheme of the grinder allows you to correctly determine the cause of its breakdown

With good condition of the cord, buttons and brushes should pay attention to the condition of the electric drive

What spare parts for the Bulgarians change independently, and how to properly serve the power tool

Bulgarian in the house. Like a telephone connection. When she is working. No one remembers about her. It is worthwhile to break down. It immediately becomes obvious that the tool cannot be dispensed with a day.

Independent repair of this useful electrical appliance can even be a novice master. And for this you need to know what spare parts for the Bulgarians can and should be changed yourself.

First, consider the device of the grinder:

Anchor. Inner mobile engine component. Usually one whole with a working shaft, through which the energy of rotation is transmitted to the gearbox.
Collector. The switching board of the anchor. Through his contacts, the operating voltage from the brushes is applied.
Electric brushes. Contact elements pressed to the collector plates.
Stator. External engine winding inside which the anchor rotates. Located along the inner contour of the tool body.
Gearbox. A mechanical component that reduces the momentum on the working shaft, while increasing the torque.
Corps, holding handles, launch key, revolutions regulator, power cable.

A detailed description of what the Bulgarian consists of

One of the components usually fails, so the expression “the grinder has broken” in a sense illiterate.

If the case is intact, and the winding has not burned out, it is quite possible to restore the tools of the tool on your own. Spare parts for Bulgarians are available in specialized stores. And you can choose the right part even for a rare model. Most components are unified.

Self.Elimination of Ushm malfunctions

As a rule, breakdowns in the grinder are associated with the electric part. Mechanics breaks only with untimely maintenance (especially the lack of lubrication).

The malfunction is cheaper and easier to prevent when its first signs appear:

Sparking inside the grinder body, in the area of electric grid;
Fuzzy trigger operation;
The revolutions change spontaneously;
The engine turns on. Turns off when the tool position changes in space;
Ushm suddenly stopped working.

No matter how trite it sounds, you first need to check the voltage in the network and in the outlet, or the extension cord from which the power tool is written. Then check the serviceability of the supply cable.

It is necessary to open the body of the grinder, and check the integrity of the supply wire visually and with the help of a tester. Reliably connecting the contacts of the device, intensively bend the cable, observing the indications of the indicator on the tester.

If a cliff is detected, replace the wire entirely, or restore the fracture with a refractory solder. Then reliably isolate the repair site of the heat.Ousse tube. Island for such a case will not work.

If the cable is working. We move on to a standard malfunction No. 2. Most often brushes burn on the grinder. Seeing the symptoms is quite simple. The grinder sparkles inside the case during operation.

Why brushes burn in the corner grinding machine?

In the attached figure, the electrical circuit and the device of the components of the electric motor are clearly visible.

Image of the tool electric motor

Ushm engine operates in extreme conditions. Despite protection, dust gets inside, most often in the form of small metal sawdust. Metal. As you know, is a conductor.

When it gets into the contact zone of brushes and collector, microsypses occur and copper plates are very warming up. Melting and mechanical connection of the collector contacts may occur.

Type of the electric motor collector to be repaired

In this case, the brushes overheat, and the working surface intensively burns out. Hence sparks and increased wear. Another reason why the brushes sparkle is to get inside fine sand and wooden dust.

When the collector is contaminated with sawdust. The contact between the brushes and the collector is disturbed, and sparking occurs under the intensive load, with all the ensuing consequences.

This simple procedure will extend life, both brushes and an anchor collector. It is advisable after each dusty work to at least sprinkle Ushm, especially in the area of ventilation holes.

How to replace brushes on a grinder?

As a rule, brushes along with a spring block are inside the handle of the tool. This design allows you to save on the production of the case, and make it more compact, and, therefore, convenient.

The brush holder is in the instrument handle

There are specimens in which the fasteners of the brushes are made out of the case. This on the one hand allows them to inspect and replace them faster. However, it is better to change the brushes in combination with cleaning and lubricating the power tool, so the case still will have to disassemble.

It is also advisable to extract the rotor from the stator, and measure the resistance of the windings. It should be the same.

Measure the resistance of the windings in the rotor

Then you should clean it from dust, grease the bearing and, if necessary, grind the contact plates of the collector with sandpaper. Zero. After this procedure, the grooves between the contacts must be cleaned with a hard brush from copper dust. A working collector should look like this:

Examine the brushes, and in the case of chips, cracks, and other signs of wear on them, replace with new. In the kit of the grinder, when buying, there is often a spare kit.

If this was not, it will not be difficult to find a suitable copy in the construction market or in specialized service stores. These are standard spare parts, so you can always choose the right.

Do not take a larger brush with the aim of staring them under your seat. The material is very fragile, easily breaks.

Then inspect the coal naots. Worn elements of often irregular shape with damaged edges. The brushes of the same shape should be purchased with the same brass plate-zamki or terminals.

Bulgarians with the rear handle

Bulgarians with the rear handle allow you to get to the brushes in a slightly different, simpler way:

Near the handle it is necessary to find a small repair window closed by a plastic plate, which is recorded by a self.Tapping screw.
It is necessary to unscrew the self.Tapping screw, put a plastic plate in the groove with a screwdriver, remove it from the case, opening the repair window.
The following actions to replace brushes are the same as that of low.Power Bulgarians: free the tape spring (1), free the plug (2), remove the brush from the guide block by the wire.
Then insert a new brush, connect the plugs, fix the graphite rod with a tape spring, close the repair window with a plastic plate and screw the screw.
Repeat all actions with the second brush located on the opposite side of the body.

It is possible that other methods of replacing graphite brushes, due to the structural features of grinder may exist, may exist.

The most elementary way, without disassembling the case

Some manufacturers approached the possibility of replacing brushes very rationally. In the case of the machine there are threaded traffic jams. And the whole process of checking or “repair” takes two minutes (for both graphite contacts):

Dill out the plug with a screw.
Put a thin screwdriver with a thin screwdriver and remove the brush.
If the brush compared to the new one lost 70. 80 % of the length, then it should be replaced. Otherwise, the old graphite contact must be made by the same side as it was before extracting to exclude the process of grinding. After all, brushes wear out unevenly due to the fact that they come into contact with a rotating cylindrical surface.
Plunge the cork. Attention! The cork can be screwed up and upside down. Therefore, you need to make sure that there is a groove under the screwdriver on top. Otherwise, there will be difficulties in the next toleration.
Repeat all actions with a brush located on the back of the grinder body.

This is the easiest way to replace the brushes in a grinder that does not provide for disassembling the case. Therefore, when buying a new tool, this nuance can be taken into account.

How to work Ushm (“Bulgarian”)

RABOTOTE OF A corner grinding machine (universally called a “Bulgarian”), one of the most traumatic at a construction site and in repairs, therefore, everyone who picks up this tool you need to have a clear idea of how to work correctly, how to care for it, to know the safety rules.

Device and principle of operation of the grinder

The grinder is a fairly simple and effective tool. It consists of a shock.Resistant case equipped with one or two handles and the working part. Rotating at a high speed of the shaft, on which interchangeable nozzles are fixed. The axis of rotation of the shaft is perpendicular to the device body.

Small Ushm (about the sizes of the Bulgarians just below), you can work by holding the tool directly beyond the case, but use a grinder with a disc of 180 mm or more, you need to hold it for two handles. Without this, work is extremely dangerous or impossible.

The upper part of the working nozzle (disk), not used in work, is closed by a safety steel casing.

HILTI AG 115 Angle Grinder. Carbon Brush Replacement

Important! Removing a protective casing is allowed only in exceptional cases, for example, when grinding with soft nozzles. Cutting with a grinder without an installed casing can lead to serious injuries!

Large parts are cut with powerful, massive units with a diameter of a cutting disk from 230 mm or more. In everyday life and in most repair and construction work, it is convenient to use a grinder with a disc up to 180 mm.

Even a small car, with a disc 150 mm or a crumb at 115-125 mm, will noticeably facilitate the cutting of MDF, plywood, plastic, thin metal.

For the most part, electric engines are power plant for Ushm, however, there are models with → pneumatic drive (the link tells about the differences of pneumatic tools from electric).

The speed of the Bulgarians is also noticeably different: the more powerful the device is and the larger disk, the lower the speed. And if in cars with a disc 230 mm is 1.9-2 thousand. Rpm., then in small devices the speed of rotation can reach 14 thousand. Rpm.

Grinding a grinder

First of all, we will figure out how to grind a grinder, and which nozzles use at the same time.

For grinding and stripping, reference discs, cups, wire nets of various shapes and other devices are used. Both completely made of abrasive material and having a steel or plastic base on which various abrasive linings and even sandpaper are attached.

Cleaning disk is noticeably thicker than the detachment. Its shape can be flat or plate. If such a “plate” is deepened, and make the edges narrow, we get a bowl.Shaped grinding nozzle, or simply a “cup”.

Grinding the whole plane of the nozzle or part of it. In this case, the axis of rotation is located almost perpendicularly processed surface.

Advice. The anterior rotary hilt of the USM (if any) when grinding is better expanded so that the handle axis coincides with the direction of the axis of rotation of the nozzle. To work as a grinder when the hand is located not on the side, but above the nozzle is usually more convenient, especially on the surfaces of a complex shape.

Now about how to cut a brick, concrete, metal, etc.D. For this, special circles are used, which are called, cutting.

You can cut both metal and brick with a grinder

In addition, if there are no problems with abrasive disks, then a steel disk with spraying or inserts intended for cutting stone will quickly fail if they cut metal.

Important! It is strictly forbidden to cut thick wooden boards and logs with a grinder. It is even more dangerous to do this by installing a disc from a circular saw on a grinder. Unfortunately, such a violation is quite common and the consequences are sometimes very tragic.

Cutting is performed by the edge of the disk, while the pressure force should not be significant, the tool should be kept almost “on weight” and without distortions.

Cut wood using a lot of Ushm using a special wood disk. They are quite new and are available on sale.

Shtroting with a grinder

Builders are called a strobic strobed in the wall, in the ceiling or floor channel for placing communications.

Let’s look at how to stroke a grinder, since this type of work is performed by cutting circles, it has its own characteristics.

For the installation of the sede, we cut out two parallel lines, the desired depth, after which the material between them is chosen with a perforator or chisel with a hammer with a hammer.

To work on concrete or ceramic brick, it is better to use a steel disk with diamond spraying or cutting inserts. Plaster, especially lime or gypsum, easily cuts an ordinary abrasive disk on stone.

The work is markedly simplified if the strokes are cut with a grinder with a special nozzle. A stroberase. Such a nozzle has two disks, the distance between which you can adjust and cuts out neat parallel lines in one pass. You can find out more about the methods of stripping channels for wiring in the wall → by link.

I recommend: how to choose a grinder for home, cottage, garage, for work

Some masters “get out of the situation”, installing two discs separated by washer, but using a grinder, thus, is not entirely correct. Although the work is accelerated:

Corner grinding machine device

To realize the operation of the mechanism and why breakage is likely, it is necessary to have an idea, at least a schematic, about the main components of the tool.

Regardless of the model, manufacturer and technical features, no matter what Bulgarian

The mobile part of the electric motor, it is called an anchor, or, what will be at the technical level correctly, the rotor. Usually, this element is combined with a working shaft transmitting a torque.
Contacts of the collector, which is a switching fee through which the voltage from the background is removed.
The brushes clinging to it provide electronic contact. With a weak press, they begin to spark very much.
Inner motionless winding. Stator. The anchor rotation in it is achieved due to electrical induction.
Mechanical reducing gearbox for speed adjustment.
The remaining components: a case, usually plastic, handles, a launch button, a cable supply.

As a working tool, Ushm is subjected to the highest loads and the overstated time of continuous operation. Inside of the body, despite the highest density, at times dust, small fragments of the processed materials, scale, is at times. This does not affect both mechanical parts and the electronic part.

How to replace carbon brushes in a mixer/grinder

Brushes for a grinder are the main signs of tool malfunctions and the rules for replacing elements (100 photos)

Bulgarian (or angle grinding machine, abbreviated Ushm) is an indispensable tool for construction and repair work. The result of the loads during operation of the device is the need to replace the parts. With a careless attitude to repair, the entire mechanism may be damaged.

Especially often brushes need replacement. Therefore, it is worth considering what is the cause of the breakdown. And how to change the brushes on a grinder.

Signs of a malfunction of the mechanism

In the process of using a grinder, it is impossible to avoid small garbage from the mechanism. This leads to the fact that in the area of copper plates there is a closing and overheating. An increase in temperature leads to the fact that the brushes begin to melt and burn.

And as soon as the dimensions are close to the minimum, indicated by the manufacturer, the master can observe the following alarming signs:

Metal brushes on the grinder begin to sparkle;
When working, the tool has jerks or twitching;
With severe wear of brushes, the smell of Gary may appear.

Some manufacturers of Bulgarians use special types of protective brushes. They are equipped with a special device that controls their length. As soon as the parameters of the parts do not meet the requirements, it blocks the operation of the mechanism up to the elimination of the malfunction. This measure helps to protect the entire tool from failure.

Rules for replacing brushes in grinder of different manufacturers

The wise master will not wait until the tool will give signs of breakdown. Since the replacement of brushes is part of the service of the grinder, it will regularly clean the collector about pollution and inspect these details.

It is worth remembering that manufacturers of brushes for a grinder always indicate the minimum size in which the product still retains its performance. This indicator may vary slightly depending on the manufacturer.

Most of the tool models suggest two options for the location. In the first case, they can be inside the handle. In the second version, the brushes are placed on the case. However, regardless of the location of these details, in order to prevent prevention, it is worth disassembleing the tool and lubricating all its components.

Before starting the analysis of the grinder, you need to de.Energize it. Then it is required to disconnect the tips, inspect the holder. After extracting the brushes themselves, a thorough check is required for the presence of mechanical damage, which will indicate a wear that requires replacing the part.

Here are examples of repair work on the grinders of leading manufacturers:

On Bosch grinders to remove brushes, just open the stator body handle. The device of this brand will not work with the length of the working brushes less than 8 mm.

Buying a grinder, you can find popular spare parts in the starting kit. You can decide on them which brushes to choose.

Not for all types of grinder it is easy to choose the right option even in a special store. In this case, it is required to purchase a larger brush to file them to the required.

How to choose brushes for a grinder

New technologies involve the production of brushes by pressing carbon material using high temperatures. This method increases the service life of parts due to less wear.

There are several main types of this detail:

The most common graphite brushes are considered. For this, the main material from which the part is made is given to the form. Then it is covered with a graphite layer and burned at a temperature of 2500 degrees. As a result, a strong, wear.Resistant compound is formed, the advantages of which pay off high cost.

Coal brushes are considered the cheapest and short.Lived option. Low indicators for wear resistance are formed due to the lack of thermal treatment.

Metallographic brushes are considered the most reliable option. In addition to carbon material, the coating includes copper with the addition of lead, tin or silver. For household appliances, such parts are extremely rare due to the high price.

We will summarize: replacing brushes is an important part of the maintenance of the grinder. Inattention in this regard can lead to more serious breakdowns, such as the destruction of the anchor collector plate. When replacing, it is important to correctly disassemble and assemble the mechanism, simultaneously lubricated its main nodes.

By determining which brush is better in a particular case, it is better to contact the instructions or those passport of the device. If there are additional questions, it makes sense to seek advice to the service center.

Why spark and burn brushes on a grinder. Repair or replacement of the Ushm grinder

It is difficult to imagine an arsenal of a home master without such a popular power tool as Ushm or Bulgarian Corner Ground. Ushm gained its popularity due to universality, since this tool can be used for cutting, grinding, sawing, polishing, stripping, gear and other works. And you can process absolutely any materials. During the operation of the tool, different breakdowns arise, and one of the most common is the sparking of brushes on the Ushm. Why do not many know the brushes on the grinder, so we will understand this issue, and also find out why they burn and how their replacement is performed.

Before you find out the reasons for the sparking of brushes on the grinder, you need to deal with their purpose. Collector brushes are used not only in the design of angle grinding machines, but also in the device of all modern power tools. Drills, perforators, electrolobsics and others. In the design of the grinder and other power tools, 2 brushes are used, which have a simple design. This design is based on the following elements:

The main part. Has a rectangular shape, and is made of coal or graphite
Contact is the wires of the corresponding diameter through which the electric current occurs. Contact connects the wire to the graphite part
Spring. A mechanism that provides the clamp of the main part to the collector. There may not be a spring element, and this suggests that such a brush is intended for installation in a power tool where the brush holders have a built.In clamping mechanism in the form of a curved plate

Devices are designed to transfer the electric current to the rotor of the power tool. The removed voltage from the stator is supplied to the rotor, which is reproduced using coal brushes and collector. The current supply to the collector provides its rotation. When rotating the rotor of the device, the device is in contact with the collector (copper lamellas. Conclusions of the anchor winding), thereby ensuring the continuous flow of electric current.

In the process of applying devices, they are abrasion, therefore, they belong to the category of consumables. The service life of brushes depends not only on the working resource of the power tool, but also on the materials from which they are made. The wear of the brushes affects not only the mechanical effect due to the friction force, but also the thermal. Electric current when passing through the conductor causes its heating. The greater the current strength, the higher the heating temperature. When passing current through graphite brushes, they also heat up. The higher the load on the power tool, the higher the current, which means the temperature increases, which negatively affects the integrity of consumables.

It is interesting!There are no differences between the brushes for the corresponding power tools (with the exception of the fixing method), since they are selected exclusively according to such a parameter as the dimensions of the main part.

Replacing the brushes of wipers (wipers) is important and, fortunately, a fairly simple part of caring for a car. Brushes must be changed at least once a year. The need to replace can be understood by wear of rubber and its cracking. [1] X source of information, you will also begin to notice that the brushes leave behind water, traces or simply wipe the glass unevenly. It is usually reasonable to change both brushes at once, given the fact that if one has worn out, then the other will soon become unusable. [2] x The reliable source of Consumer Reports to the source to replace the wiper.Cleaners’ brushes on your own in just a few steps. To find out how this is done, follow our recommendations.

Some glass cleaner mechanisms depart from glass by only a few centimeters. If this is in your case, then do not make efforts to pull them further from the glass.
On some cars, it may be easier to turn on the wipers, and when they set in motion, turn off the ignition. So you can raise the lever, and it will be more convenient for you to remove the brush from it.
You may need to knock on the brush or pull it stronger to remove it if dirt or traces of corrosion accumulated at the connection place.
Sometimes the brush is easier to remove, if you press it into the lever, press the latch and then remove it from the lever.
Now the levers are bare pieces of metal. If you leave them in a standing position, they can hide back and damage the windshield. Therefore, for the sake of your own calm, carefully lower them onto the glass and leave it so until the moment when you are ready to put on new brushes on them.
For greater reliability, put rags under them so that the levers rest on the glass through them.

Take a new brush. If the left and right brushes have different lengths, do not confuse the side of the location of the brushes. Press the moving latch on a new brush so that it gets into a perpendicular position.

Check the angle of installation of the lever. If the lever is located at an irregular angle, wipers can knock. In the middle position of the brush should be at an angle of 90 °. The average position is taken into account, since when moving along the windshield from top to bottom, the angle will change due to the curved shape of the glass.

Brushes for brushing wood on a grinder. Wood brushes are the main types and features of application

Bracing wood: selection of brushes and tools, processing wood with your own hands | Construction portal

Citizens who have lived in metal dungeons of stone jungle all their lives are gradually losing interest in faceless urban interiors, giving preference to classical, vintage and rustic styles, characterized by emphasized personality. An integral component of these interiors is a tree. A popular finishing material, thanks to which they acquire uniqueness and original beauty. However, there are also tricks here-if country-and eco-style are often complemented by a tree in its original natural form, then within the framework of vintage and even classical styles, a more appropriate tree will have a more attractive and noble appearance. Almost any element of the interior can be made from it: it can be a vintage lamp, and a wooden chest of drawers, and the classic use of wood in the interior. The manufacture of window sills and doors. Under natural conditions, the process of aging wood takes more than one year, intricate patterns on its surface are formed slowly and unevenly, which makes the aged wood a rare and expensive material. However, the technology does not stand still, and over time, the method of artificial aging of wood was developed, called breasting. Interest in such a method of processing wooden surfaces is manifested not only by lovers of luxury vintage furniture, but also by owners of suburban areas who decided to diversify the interior decoration of summer houses. Given the relevance of the problem, in this article we will consider the essence of the process of brushing wood, the main varieties and tools necessary for its conduct, and also tell you how to brush the wood with your own hands.

Town of wood: basic information

If you carefully consider the appearance of the wood on the cut, you can see a peculiar pattern. Annual rings in which dark and light colors are interspersed. This pattern is based on the alternation of solid (dense) and light (more loose) fibers, and the latter are more susceptible to time and aggressive climatic factors, which leads to their gradual wear. That is how the formation of annual rings happens, which over time not only acquire density and contrasting shades, but also a visible volume. This is the basis of the natural aging of wood. A process that occupies more than one decade. Thanks to the lightning development of innovative technologies, a unique opportunity to artificially accelerate the process of aging wood has appeared at present. This can be implemented in practice using the brushing method that got its name from the English word Brush. Brush. In the Russian language there is a similar term, which is designated as “structuring wood”.

What is wood brushing: the essence of the method

Bracing is the method of artificial aging of wood, which implies the use of specialized tools and methods. The branding technique is based on the mechanical processing of the wood of special metal brushes, with which the milder upper fibers of the material are removed. Thanks to this technique, the hard surface of the wood is exposed, on which the texture of the material and the structure of the annual rings are clearly visible, as well as a beautiful relief that emphasizes the aesthetic type of finishing material. However, this does not end the process of brushing. To emphasize the relief and make the structure of the wood even more distinct, it is distinguished by color, which gives saturation to natural shades. For this, uneven staining of a surface treated with a metal brush is performed, while the cavities formed as a result of the removal of soft fibers are painted in darker shades, and the surface of the texture is in lighter. Thanks to this technique, the relief of wood becomes as noticeable as possible.

Important! In order for artificially aged wood to acquire maximum similarity to the material, the aging of which took place in a natural environment, experts recommend painting material that previously underwent branding is gray. Without waiting for the complete drying of the paint, it is lubricated from the relief surface. Thanks to this technique, the impression will be created that products from artificially aged lumber stood in the open air for at least 10 years.

Important! If natural aging negatively affects the operational characteristics of wood, weakening its structure, then thanks to the artificial aging carried out by the method of breasting, the material acquires additional strength.

The method of artificial structuring can be used in the framework of wood processing of both solid and soft rocks. The main requirement to which the wood should be met, subject to breastfeeding is the presence of a clearly expressed texture and clearly noticeable layers of various hardness. Such materials include oak, pine, walnut, larch, wenge and ash.

As for alder, cherries, birch, tick, maple and beech, in relation to these breeds, the branding method will be proven ineffective, since a distinctive feature of these trees is a small.Fiber structure without a pronounced layer.

Advantages of artificially aged wood

Wood, which has undergone artificial structuring, acquires an original appearance that meets the latest fashion trends;
Brained wood acquires resistance to decay and exposure to various insects;
Having done the brushing of wood with your own hands (the video presented in the article will simplify this process), you can independently make a lot of exclusive things that will not only last a long time, but also emphasize the exclusivity of any interior;
Having made a decorative decoration of common and quite cheap lumber, you can create an artificial imitation of exotic varieties of wood, the cost of which significantly exceeds the initial price of raw materials.

Wood brushing tools

At first glance, the process of artificial structuring of wood may seem difficult, but its implementation is even in an inexperienced master, if there is a certain set of tools at his disposal to save time and effort spent to work. In addition, it should be noted that the brushing of wood can be carried out in both manual and mechanized ways, which is more determined by the tool used. Depending on the method by which the wood is breaking, the tool can be the following types:

Classification

As already mentioned, electric shows can be classified according to the material from which they are made. Graphite brush, as the name implies, is made of graphite into which soot and binding elements are added. This type of current coordination is most often used for crawls.

The coal brush is made of the same material, but without heat treatment. Such a product is abrupt much faster and is practically not used for a grinder. It is important not to be mistaken when purchasing brushes to replace. Coal brushes on the grinder will not last long.

The metallographic brush is used in large industrial units, and it is unlikely that it will be possible to install it on a grinder. This is the most durable product that has a very high price. The variety of cord.Shaped is much larger, their shape, material and size are significantly vary, which is determined by the variety of use of such equipment. They can also be classified according to the material from which they are made. The most popular are brushes with a metal pile. Metallic rotor. Rather universal nozzle. For the manufacture of such products, both metals and alloys are used.

Steel roots are used to work on metal. Stainless steel brushes are best used along stainless steel or aluminum. Often steel pile is covered with brass, such brushes are not corroded. There are purely brass brushes. Despite the greater softness, they have a number of advantages: a relatively soft effect on the material, the absence of sparks when working at high speeds, the absence of scratches when processing the surface.

Wire for such brushes can be different. The twisted wire is usually the hardest, it can be collected by harnesses (they can be more gesture and can be self.Adjusted) or fixed randomly. With the help of such effective nozzles, you can remove the scale from welding or rust. The corrugated cordchit has a wave.Like curved pile and, unlike the previous type, affects the surface not so intense. With its help, you can clean the surface from the old paint.

Brushes with even pile are widely used, they are the most universal and can be used on any surface. Their effectiveness can be slightly lower than that of specialized nozzles. Polymer pile nozzles, for example, nylon, are used to polish various surfaces, including metal. You can successfully use them for wood work. To highlight the texture or final processing. Plastic brushes are often used to work with soft materials.

The brushes can be divided in shape.

The cup is used to work with large surfaces. Its shape follows from the name. On such a brush, the clamping nut is most often fixed immediately, since a special key, provided for in the kit with a grinder, cannot be applied to it. The conical brush is used to work with concave surfaces. Radial, as a type of flat brushes, is used to process hard.To.Reach areas. The disk, the most common type of cord.Shaped, also has a flat shape and can be used to process the most diverse surfaces in the area.

And also the cord.Shafts are divided into dimensional groups. The diameter of the brushes is determined by the technical capabilities of the grinder and the area of use of this nozzle. Brushes with a diameter of less than 115 mm are usually used to process small surfaces. A circle of more than 200 mm for a small grinder is better not to use, you will have to remove the protective casing, and this is a violation of all safety standards. Such large brushes are usually used to process overall structures and only with the help of large powerful craftsmen.

The most acceptable household purposes is the diameter of the brushes 125 mm. You can offer the fourth classification of corticacles. On the use of. The brand brush, the name is given from the name of the technical operation, which is carried out using this nozzle. Dyeing. Preparation of the surface for subsequent processing: removal of rust, paint, pollution. At some stages, this is the process of chemical exposure to the surface of the product, but the initial processing consists in mechanical surface cleaning. Metal (steel or brass coating) brush is used for mechanical painting. The task of such processing is the removal of scale, oil spots, minor defects, burrs and the like. Without dyeing, it is sometimes difficult to assess the quality of the weld, the bastard can hide some defects.

Forms

The structure of the location of the pile and the shape of the product depend on the work for which the nozzle is intended for the grinder. A competent choice is able to make life easier for the master performing work. The instrument market offers to consumers brushes of the following forms:

This is why NOBODY will tell YOU this ANGLE GRINDER Hack!

Chalice. Cordrates in the form of a cup do a great job with hard processing of large areas. The vertical location of the pile on cup brushes provides the correct vector of effort.
Conical. In these devices, the bristles are located at an angle relative to the base plane. This design allows you to process parts with minor recesses on the surface.
Radial. Such nozzles are also called “brush-carzka”. They are designed to finish the products from the scale formed after the etching procedure. A special location of the pile allows you to work in hard.To.Reach places.
Disk. This form is the most common. The stubble is located on the horizontal plane of the tool. This design is not suitable for large work, but it copes with narrow recesses perfectly.

For the manufacture of brushes, a wire of various types is used:

Twisted. This type of execution is characterized by a wire twisted by harnesses in random order. The pressure on the surface is higher, however, the life is much less.
Burnt. Nozzles on the grinder with a burning pile located in strict order are favorably distinguished by the strength of the structure, as well as the effect of independent sharpening during operation.
Corrugated. The wave.Like structure of the wire gives the brush a springy effect. This softens the effect on the processed surface.

The size of the nozzle depends on the size of the grinder. Their diameter ranges in the range from 75 to 200 mm.
