Miscellaneous

For fast and high-quality erection of an object, the performance of all necessary finishing operations in construction, special technical devices are increasingly being used. Such equipment, which speeds up and greatly facilitates the construction process, is a brick cutting machine. It is known that today brick remains the main building material. When erecting brick structures, from time to time it becomes necessary to give the stone a certain shape and size. In this case, a brick cutting machine is the best solution to the problem. It is multifunctional, convenient, compact and lightweight. Such small equipment as a brick cutting machine has significant advantages over manual processing of building materials. In addition, it can process concrete, ceramics, etc.

Varieties of machines for cutting bricks

The reliable design of the machine makes it easy to cut bricks, giving them the desired shape and size. There are two types of this device: industrial and household. Their main differences are power, functionality, performance and size. Household stone-cutting machines are used mainly in private construction sites and small businesses. Among them are distinguished:

stationary and manual;
single-head and two-head;
with pneumatic and mechanical clamp;
with and without cooling system.

Main blocks of equipment:

work surface with carriage;
frame with cutting element;
drive motor;
a tank for water supply, which minimizes the amount of dust;
mounting feet.

Depending on the manufacturer, brand and model, brick cutting machines have different power, fastening system, cutting disc diameter, cutting depth. Modern stone cutting machines are equipped with a tilt angle control system, which allows cutting bricks at an angle from 0° to 45°. In addition, there are models with bottom and top drive. In the first, the water tank is located under the disc. The latter are distinguished by the presence of a submersible pump. Typically, such machines are made of special steel, which ensures reliable and high-quality operation of the equipment and allows you to control the entire process of processing building materials.

When choosing a machine for cutting bricks, first of all, you should pay attention to the manufacturer, power and operating modes of the device. Equally important are the indicators of the maximum load of the machine, the length and depth of the cut, the possible angles of the cut, accuracy, width, height and weight of the device itself. In addition, you should pay attention to the volume of the coolant tank. The smaller it is, the more often you will have to add water.

Do not buy equipment from an unknown manufacturer. It usually has low functionality and breaks quickly. Therefore, in this case, it is not worth saving. A branded machine is a guarantee of quality and long, reliable operation.

The process of cutting bricks on the machine

Working on a stone-cutting machine requires certain skills and safety precautions. Therefore, before starting work, you should read the instruction manual for the machine and follow all its points.

For reliable and correct operation of the machine, first of all, a flat, convenient and safe place for installing the machine is selected. All necessary markings are applied to the bricks. The workpiece is fixed at the desired angle on the work surface. Then, a cutting disc is brought to the cut site, the power is turned on, the required rotation speed is selected and smooth cutting is made with an accuracy of a millimeter.

Do you have any questions? Ask them in the comments.

Not a single building can do without stone, brick and similar wall materials. Durability and affordability make them the primary and most reliable materials for building walls, stoves, fences, and paving sidewalks and paths. In the process of laying bricks, sometimes there are emergency situations when the standard dimensions of a block or brick do not correspond to the required dimensions. Sometimes it is necessary to slightly change the shape of the brick, and then only cutting can ensure a quality fit of the block in place.

Working principle of brick cutting machine

The most effective method of cutting bricks remains cutting with a machine. Although this is not the only way to give the stone the desired size and shape, it is the most accurate and fastest of all, which we will discuss later. Brick cutting machines, like any tool, can be both industrial and designed for use at the household level. We will not consider equipment for sawing stone blocks from rock, as we will leave out of the review and machines for jewelry work.

A machine of any level of complexity is a solid and reliable frame, a cutting element, a drive system and a control and start system. This sounds too loud for the simplest cutters, however, without these elements we will not cut any brick. For complete control of the cutting process, the machine must have a fairly heavy frame and a mechanism that would hold and feed the brick under the cutter.

Brick cutting machine BALI MEKANO, price

An example is a general-purpose machine. It is not very large to enter the category of industrial, and just can meet the needs of low-rise construction. The BALI MEKANO universal device fits into the middle price category. A brick cutting machine, the price of which is about 85 thousand rubles, works out its money one hundred percent. The BALI MEKANO brick cutting machine has a wide range of cutting depth adjustment, so it can handle not only brick, but also thermoclay and recycled concrete. There are no difficulties in working with standard materials, including bricks. The maximum cutting height is 200 mm in one pass. The machine can use diamond blades with a diameter of 400, 450 and 500 mm, and it can be connected to a conventional 220 volt network.

To cut such a durable material as brick, you need a special cutter, in which the role of the cutting edge is played by diamond, topaz or other corundum. With the advent of artificial diamond, the possibilities of cutting tools have expanded significantly, and circles for working with stone have become not uncommon. The diamond disc consists of a metal core and a crown, on which the diamond grit is applied. There are four methods for making cutting discs. Both the resource of the disk and the performance depend on the manufacturing method.

The galvanic method involves placing the edge in an electrolyte with artificial diamonds. Such discs have good cutting ability, but have a short resource.
Cold pressing. The disc is made by pressing a mixture of metals with diamond chips in a special mold. Cold-pressed discs work well, but you can't count on long-term use.
Hot pressing. Similar technology, only when pressing, the temperature of the press is increased. The discs are the strongest of all listed, but the cutting ability of the edge is somewhat inferior to cold pressed discs.

The most technologically advanced disks are disks made using silver soldering technology. Diamond segments of the edge are soldered to the base of the disc, and after that the diamond layer is built up over the entire cutting part. But after that, the disk is not yet ready for use. The surface of the edge is processed until a perfectly flat surface is obtained. These cut bricks perfectly and serve for a long time, but are very sensitive to high temperatures, therefore, during operation, they require forced cooling with water.

Cutting a brick with a grinder

Naturally, not everyone can afford to have a brick cutting machine on the farm, so there is an alternative processing method - an angle grinder, or a grinder. To do this, you need a grinder, which is designed for a minimum circle diameter of 200 mm. Most often, discs with a diameter of 230 mm are used for cutting bricks. A smaller disc simply cannot cut the brick to its full thickness, so you have to turn it over, and this is an extra waste of time, and the quality of the cut will suffer.

The more powerful the grinder, the easier it will be to stab into the body of a brick. For normal comfortable work and in order not to overload the tool, the grinder should be no weaker than 2 kW. When cutting, it must be borne in mind that the marking should be carried out taking into account the thickness of the disk, which is approximately 2 mm. The cutting process itself is not that difficult, but requires some skill, so before cutting expensive facing bricks, it is worth practicing on a rough brick or on debris.

There is no material that could not be processed. Everything is processed, so even if you do not have a brick cutting machine, you should not despair. The grinder will save the situation, and the masonry will turn out to be even and neat.

You can cut the brick yourself with the help of hand power tools, special machines and installations. Choosing the right tool depends on the scope and type of work.

The main problem is a lot of dust. To avoid harmful consequences for a person, the settling of small particles on surrounding objects, especially at home, experts recommend using the wet cutting technique - moisten the fixtures with water and, if possible, do not carry them out indoors.

List of tools suitable for cutting

Devices needed in the process of laying out the walls:

angle grinder (grinder) with cutting discs for stone;
petrol cutter;
a circular saw;
stone cutting machine.

To make cutouts in masonry:

Bulgarian;
petrol cutter;
wall saw - disk or cable;
laser machine.

1. Angle grinder, grinder and circular saw.

For a small volume at home, an angle grinder with a power of 2 kW or more with a stone disc with a diameter of 230 mm is optimal. Cutting wheels for grinders are of two types:

Abrasive. They are suitable only for one-time work, as they are quickly erased. The main advantage is an affordable price, the disadvantage is that they are often deformed and destroyed in the process. Not suitable for wall cutouts.
Diamond. These wheels are suitable for long-term use, do not grind off, provide the best result, safety. They are much more expensive than abrasive ones, but the difference in price is offset by the durability and quality of the cut.

There are four types of diamond blades for angle grinders:

Solid (Crown). Their edge is continuous, which ensures the fastest work, perfectly even cuts without chips. Solid circles are suitable for the wet method.
Segment. Used for dry cuts, they have evenly spaced cuts on the edge, directed towards the center, which divide the circle into even parts - segments.
Combined (Turbo). Serrated edge, consisting of oblique grooves. This type is universal, suitable for dry and wet methods.
Turbosegment. Suitable for dry cutting only. Their cutting edge is also serrated, but divided into segments. Special shape improves performance.

When marking, a margin of 1-2 mm is taken into account for the displacement of the cutting element, otherwise there is a high risk of cutting off more than necessary. If there is no experience, then it is better to first try to process an old brick or a fragment of a new one and adjust the amount and direction of the indent.

2. How to use the grinder correctly?

Be sure to keep the angle grinder strictly at right angles to the surface.
Under the block to be processed, place another or a wooden block.
It is not necessary to put pressure on the tool in the process, its own weight is enough.
If the diameter of the disc is not enough, then first make cuts around the entire perimeter, then break it and process the cut.

If you want to make a cutout with a grinder in a brick wall, then it is correct to mark it first. Then, through holes are made with a puncher, after which the angle grinder is cut along the basting.

A circular saw is most often used for woodworking, but stone circles are also on sale. The circular is usually installed on a special machine. The element must be firmly fixed. After turning on the saw, the block is brought to the disk. Cut smoothly, without jerks and pressure.

3. Petrol cutter.

This tool works on the same principle as an angle grinder, but is larger in size, has a very powerful gasoline engine, and can make holes in brick walls of any thickness. Equipped with a water supply system, which ensures a minimum amount of dust. For disc options, there are diamond and abrasive wheels.

In addition to disk, there are reciprocating gas cutters on sale, their cutting part is a diamond chain. This type is more suitable for walls, while disk ones are more convenient to process a piece element on their own.

4. Stone cutting machine.

Equipment for cutting stone on an industrial scale. His device:

table with legs;
metal frame with devices for positioning and fixing bricks;
diamond disk;
engine;
drive unit;
water supply system.

Relatively light weight (about 60 kg) and compact dimensions make it easy to transport the machine from one construction site to another. Main advantages:

high accuracy;
high speed;
the person performing the cutting is facing the cutting disc and has a good view of the markings.

Work order:

Put markings on the brick.
Fix on the table.
Bring the cutting disc to the place of the future cut.

5. Wall saw.

Professional tool for a large amount of work on diamond cutting of structures, including brick, with a thickness of 320 to 1005 mm (depending on the brand).

Characteristics:

Type of drive. Available with electric or hydraulic drive. The former are quieter, the hydraulic ones are more powerful, but require a large number of additional devices (liquid reservoir), and in the event of a leak, they can cause damage to nearby devices.
Engine power. The maximum depth of cut depends on it.
Control type. Manual with a steering wheel up to 1.4 m long and automatic with a remote control panel.
Stationarity. On sale there are manual wall cutters, similar to a grinder, and large mobile units, including those with remote control. The former are more convenient where maneuverability is important, mobile (mounted) are designed to work with walls of great thickness.
By type of cutting unit. Distinguish disc and cable machines, the first cutting is carried out due to the rotation of the circle with a diamond coating, the second - due to the reciprocating movements of the chain with diamond segments. The disk unit can cut not only in a straight line, but also in a circle, its console rotates 360 degrees. Rope cutters are suitable for cutting at strictly specified points, including in hard-to-reach places at an angle that is inconvenient for other equipment. The same type is used if the thickness exceeds the dimensions of the diamond wheel of the disk equipment.

6. Laser installation.

The most modern way is to use a mobile gas-discharge laser device. The beam can make cuts of any given shape and size. Main advantages:

high speed - up to 1 meter per minute;
the cut does not need to be processed;
low noise level;
wall material is not deformed;
ease of mode change.

Disadvantages - high cost of equipment and its use; high energy costs.

In the process of performing construction work, it often becomes necessary to cut a brick, giving it a non-standard shape. To do this is not as easy as it seems at first glance. Cutting bricks requires a certain amount of skill and skill. There are several ways to cut bricks. In order to cut the workpiece with high quality, you should carefully familiarize yourself with the cutting technology, which will avoid possible cracking and damage to the material.

Brick cutting methods

In order to get a brick of a certain shape, you need to make some effort. First you need to take the necessary security measures. Protective goggles must be purchased. They are needed so that the brick chips do not get into the eyes. You will also need gloves and a respirator.

There are the following ways to cut bricks:

chisel splitting
cutting with a circular saw
machine carving
cutting with a petrol cutter
slicing grinder

The brick cutting process consists of several technological stages. In order for the cut to be even, you must first apply the markup. The dimensions verified in advance are applied to the surface of the brick using a ruler and chalk. You can not start the cut exclusively along the marking line. So you can get a part of the brick that does not correspond to the desired size and shape. The cuts should be made with an error of 1.2 cm.

Splitting irregularly shaped bricks by hand

The easiest way to get bricks of non-standard shape is manual cutting. The brick splitting operation is simple to perform. To work, the master will need a medium-sized hammer and a regular chisel. In work, the following procedure should be followed.

To ensure stability, lay the brick on a flat surface. A marking line is applied to the workpiece with chalk along the ruler. Next, a chisel is applied perpendicular to the surface of the brick with the tip down. Then you should make a sharp blow to the instrument. If everything was done correctly, the brick should split into two identical halves.

Unfortunately, this method has many disadvantages. In particular, it is impossible to determine in advance how evenly a brick will crack, even if everything was done correctly. In addition, the newly formed brick face is never perfectly even. Its uneven edges have to be hidden inside the masonry.

In production, where a large amount of work is required, special machines are used to cut bricks. Brick cutting machines are versatile equipment designed to perform large-scale tasks in a production cycle. Work on the machine allows cutting a high level of accuracy. The brick cutting machine includes the following structural elements:

metal frame
driven electric motor
diamond disc
irrigation system
fastening system

Operations on the machine are carried out with a high degree of accuracy, while the emission of brick dust into the air is minimal. The irrigation system of the working parts of the machine does not allow it to rise into the air. Cutting a brick on a special machine is not difficult, the work does not require special skills. Work on the machine is carried out in a strictly defined sequence.

First, markup is applied to the brick. Then the brick blank is fixed on the machine at a certain angle. When turned on, the rotating disk, moving, smoothly cuts the brick along the marking line.

During operation, the machine operator is located directly in front of the machine, which allows him to fully control the work process. To work with the machine, only discs of a certain model designed for this machine should be used. During operation, safety precautions must be observed. Equipment must be properly grounded.

The use of brick cutting machines helps to carry out work in a safe manner with the highest possible accuracy and speed. This construction equipment is represented by stable metal structures with diamond discs connected to an electric drive, systems for fixing products and cooling. This minimizes the process of dust formation and the risk of getting brick crumbs on the operator. Almost all modern machines are multifunctional and compact, the scope is limited only by the high price. The minimum cost of devices for professional processing is 80,000 rubles.

Tips for choosing equipment for cutting bricks

The main performance characteristics are the performance of the machine, its functionality (permissible angle, length and depth of cut) and the quality of the cut. Before choosing and buying a model, it is worth clarifying:

The value of the maximum allowable load.
The maximum diameter of the working disc, the ability to change the depth of cut (change of cutting elements).
Cutting error. It is noteworthy that most manufacturers indicate this ability as the main one, but numerical values \u200b\u200bare hard to find among publicly available information. The only way out is to buy trusted brands.
Ability to cut stone and brick at an angle.
The volume of water in the cooling system tank, control over its supply. The smaller it is, the more often you have to stop the workflow.
The stability of the support table, evenness and smoothness of the guide structures.
The presence of a removable or stationary metal casing to protect the operator of the machine (provided for by most modern devices).
Dimensions and weight, ease of movement. The factor is in principle insignificant, but machines equipped with wheels are easier to transport.
Fans for additional cooling. This modification is definitely worth choosing for large volumes of work.
Overheating control system.
manufacturer's specified warranty period.

The machine cooling system deserves special mention. On the one hand, water supply allows you to extend the life of expensive discs. On the other hand, in most even the most modern brick cutting machines with corners and water cooling, it circulates in a closed cycle. This leads to the need for frequent water changes, which is not always convenient on an industrial scale. Installing settling troughs partially solves the problem, but many users convert a closed system to a continuous one.

Buying a used machine for cutting bricks will not be a problem, this equipment has been on the market for a long time. Attention is drawn to the condition of the metal and engine, guide structures. But significant savings are unlikely to be achieved, the manufacturer's warranty obligations rarely exceed 1 year, and the intensity of the devices is high. For one-time promotions, instead of a used machine, you should think about renting it.

Brick cutting machine: characteristics of the device and its components

Brick cutting is a necessary process inherent in the construction of any object. The use of a whole brick allows you to create monolithic, even surfaces that are distinguished by excellent qualities of reliability and durability. However, it is not always possible to use a solid product, since there are places where it simply will not enter or will fall out of the appearance of the building, violating its integrity. Such places are corner structures or places of various transitions and many others. It is to fulfill such features that the whole product is subject to cutting, which for many years was carried out manually, and only recently a product has appeared on the market that allows not only to save human labor, but also significantly simplify it. Such a device is considered a specialized machine, the purpose of which is to cut bricks.

To date, such devices have become widely known and are produced by various companies, both European brands and unknown Chinese brands. Some craftsmen generally learned how to make brick cutting machines with their own hands. At the same time, the best solution is to purchase professional equipment that will serve faithfully for many years.

The device itself consists of the following structural elements:

steel frame with disc;
water container;
fixing legs;
table for cutting bricks;
engine.

As we can see from the structure of the structure, it is not particularly complex, and one can only guess why no one has made such an object before, thereby simplifying the life of builders around the world.

The advantages of a brick cutting machine and the parameters that you need to pay attention to when buying a machine

The brick cutting machine is a fairly practical and reliable device.

However, its use in the construction of small buildings can hardly be justified by anything. First of all, a similar apparatus requires a significant investment, so its use in private construction is simply impractical. Basically, such products are used for the construction of large-scale objects, where they pay off with interest. Among the advantages of such products are the following factors that allowed her to gain such wide popularity:

high productivity of the device;
minimum level of dust;
cut accuracy;
the ability to give the product any shape and size.

Be sure to wear protective goggles when working with the machine.

All these advantages have contributed to the fact that such machines have become almost indispensable in the implementation of construction work. Another advantage is the fact that they can work with various types of materials, from brick to natural stone.

At the same time, you also need to be able to choose a machine for cutting bricks. A variety of models of similar products do not just have different prices. If you do not take into account the Chinese counterparts, which have the lowest price, and focus only on proven brands of European manufacturers, then you can trace the dependence of the price category on the parameters of the device. The list of technical features that you should pay special attention to when buying such products is as follows:

device power;

In addition, having an understanding of the necessary qualities of the device, making the right choice will not be difficult.

Conclusion

Working with a brick cutting machine does not contain any difficulties and can be done even by a person who does not have such experience.

In general, the whole process can be described as follows:

Preliminary marking of the product to be cut.
Fixing an element.
Preparing knives.
Turning on the device.
Setting the required power.
Direct cutting procedure.

The sawing process is quite simple and allows you to significantly speed up the work, as well as concentrate them on the direct construction of objects, and not on auxiliary actions.

At the same time, the design of the machine is made in such a way that it does not allow holding the cut product directly in the hand. This fact significantly affects the safety of work and increases its performance. In addition, the use of similar devices allows you to get a large number of advantages, among which we should highlight the high productivity of the device and special accuracy.

All these qualities significantly speed up construction and make it not only productive, but also of sufficient quality.

How to cut bricks with different tools

Previously, the question of cutting a brick did not arise, because it was simply cut with a pickaxe. But now there are many building tools that allow you to cut blocks quickly and accurately.

During the cutting of this building material, a lot of dust is generated, so you should always use personal protective equipment: a respirator, fabric gloves, plastic glasses. According to safety regulations, all electrical equipment must be grounded.

To get an accurate and even cut, you need to apply the necessary markings to the object being processed. The necessary dimension lines are applied to the plane of the brick with a pencil using a ruler and a square.

Cutting with a power cutter

A petrol cutter is a special circular saw of an independent type, equipped with a gasoline engine. This tool has a large mass and size, so it is not very convenient for piece cutting of ceramic bricks. The cutting tool used in a power cutter can be of two types: discs or chains. Both types of tooling are made with diamond coating.

A saw equipped with a disc resembles a grinder (only larger). When installing the chain, the tool resembles a chainsaw. Due to its power, such a saw is more suitable for cutting openings and niches in brickwork, as well as for dismantling work. The power cutter is able to cope with walls of almost any thickness. A big plus is the equipment of this equipment with a forced water supply system to the cutting zone, which eliminates dust.

Cutting a brick with a grinder

When performing small-scale work, cutting a brick with a grinder is a good solution. It is recommended to use angle grinders with a power of 2 kW or more. But you should not take too powerful ones, because they are extremely bulky and heavy.

The most convenient for this are models in which it is possible to use circles with a diameter of 23 cm. Cutting equipment of a smaller diameter is also suitable, but it is not very convenient to use it, because the disk does not pass through the entire thickness of the block. The workpiece will need to be turned over, while the accuracy and quality of processing will suffer, and productivity will significantly decrease.

Technically, the method of cutting a brick with a grinder is not particularly difficult. But it is important to hold the tool correctly. It must have a secure fixation, in which the cutting edge is strictly perpendicular to the surface being machined. An inexperienced person is unlikely to immediately be able to make an even cut, so you should first practice. The width of the cutting edge and the backlash of the tool must be taken into account.

Experts advise to use a special clamping frame for angle grinders to improve the quality of cutting. In this device, the workpiece is fixed in an individual recess, and the grinder is rigidly fixed on the lever. The fixed fastening of the brick block makes it easy to cut it along, across and at any angle. More on video:

Diamond cutting brick

In order to obtain a smooth cut surface without cracks and chips, diamond cutting of bricks is used. Such work is carried out by a grinder, but with the use of a special diamond cutting tool. Any work in which such equipment appears is considered diamond cutting. The difference between these cutting elements is that they have a diamond coating on the working part.

For cutting brick blocks, it is better to use diamond discs, because they ensure the safety of the work and have a long service life. It is not economically feasible to use diamond cutting with a more powerful professional tool.

Manual tile cutter

When it becomes necessary to cut thin pieces of facing bricks, you can use a manual tile cutter. It will be convenient when carrying out finishing work, when pieces of brick with non-standard sizes and angles may be needed.

The use of tile cutters

With tongs, you can give the brick an arbitrary curly shape: perform a bevel, rounding, etc. The tool is suitable for fine and painstaking work.

Cutting bricks with a special machine

A specialized brick cutting machine is effective in case of large-scale work. It allows you to carry out all the manipulations as quickly and efficiently as possible. Due to the presence of an irrigation system, a minimum amount of brick dust is emitted into the surrounding air during processing on such a special machine. But this equipment has a rather high price, so its use for single works is unprofitable.

Some craftsmen make machines with their own hands. For this, a structure is constructed from a frame (support) and cutting equipment (circular saw, grinder). The equipment must be securely fastened and checked for proper operation before starting work.

Varieties of brick

Brick has been used in construction since ancient times. It is distinguished by enviable strength and durability. There are a fairly large number of types of bricks, depending on the material from which it is made, as well as on what it is planned to build from it (walls, stoves, etc.).

Red brick

The classic brick, made from special grades of clay and fired in a kiln at a high temperature, is called red for its color. It is widely used in various areas of construction and in the construction of individual residential buildings. The material can be cut at home with several tools that allow this to be done with a high level of precision. The cutting tool is often a diamond wheel. From what to cut, the appearance of the final structure largely depends.

Handmade facing brick

A distinctive feature of hand-molded bricks is their unusual and attractive appearance. It is used for facing works. However, it is quite expensive, so in order to save money, it is practiced to cut hand-molded bricks in half along the length of the block. So the material will go 2 times less. Cutting is carried out with a diamond tool.

Facing hollow brick

Hollow brick has internal voids, which can be up to half of its mass. There are products of various shapes on sale (with ready-made fillets, bevels, etc.), so you don’t need to cut it so often. If necessary, you can cut the material with any diamond tool (grinder, saw, etc.).

Solid brick crossbar format

The crossbar-format brick has an unusual shape: it is elongated (more than 29 cm) and narrow (about 4 cm). Used exclusively for cladding. Cutting is done with the same tool.

Clinker brick

In the manufacture of clinker bricks, special refractory clay is used, so it is much stronger and harder. Thanks to these qualities, as well as a variety of textures and colors, it is used for paving paths and courtyards, cladding facades and plinths of buildings. It is necessary to cut such material on special machines using water cooling.

silicate brick

Silicate brick is made from a mixture of lime and sand (quartz rocks). The material is quite malleable and therefore easily cut by a grinder with a diamond wheel. In the absence of this tool, the work can be done with a simple hacksaw for metal.

fireclay brick

Furnace, or fireclay, brick is a heat-resistant building material that is used for laying fireplaces and stoves. Blocks are cut on a special machine using a segmented diamond wheel.

Cutting an opening in a brick wall

Diamond cutting is considered the leading technology for making openings in masonry. The choice of equipment is determined by the complexity and scale of the work performed. The following devices equipped with diamond tools are used:

angle grinder;
petrol cutter;
joint cutter;
diamond rope;
laser equipment;
wall cutting machine.

Varieties of discs for electric tools

There are 2 types of equipment for stone: diamond and abrasive cutting discs. Abrasive cutting discs are inexpensive, but quickly grind off, prone to deformation and destruction in the process.

Diamond discs (diamond-coated wheels) are safer and last longer. By type, the edges are divided into 3 types:

Solid. Overheating of the working surface is possible and, as a result, a short service life.
Segment. The edge is divided by radial cuts into separate sections. The cut area is ventilated, but there is a risk of debris sticking between the segments during wet cutting.
Turbocharged. The teeth in the edge are arranged in a spiral, due to this, wet and dry waste is well discharged. It has the best performance and long service life.

Sometimes in the course of work on a brick small damages and scratches are formed. You can correct these shortcomings without using a grinding machine - a grinder will do. It is recommended to use an angle grinder with a power of up to 1.5 kW, equipped with special nozzles. Grinding is best carried out on a wet base.

How to choose a brick grinding disc

To carry out grinding work with the help of a grinder, special nozzles are used: cups, cleaning discs, wire mesh of various shapes.

When choosing a suitable instance, you should focus on the following characteristics:

form;
circle diameter (size);
type of abrasive used;
link type;
grain;
hardness;
structure.

Wheels can be completely made of abrasive material or have abrasive pads on a plastic / steel base.

How to get a brick of a non-standard size or irregular shape

Not so long ago, professional builders and amateurs did not even wonder how to cut a brick. They used an ordinary pickaxe and a cutting method that does not have a high level of complexity.

The process of cutting a brick with a pickaxe or a combined trowel is as follows:

you need to take a unit of building material in your left hand;
after that, you need to apply a split line with a tool on all faces of the product;
at the end, apply a sharp jerky blow to the edge of the product, while the pick and the surface of the brick should form a right angle.

This method has some disadvantages:

low accuracy;
the surface of the formed edge is uneven, so it has to be hidden inside the masonry, and this is impossible in some cases;
you cannot split a brick at an angle other than a straight one.

But, time has passed, and now there are new building tools that can be used for these purposes. They make the process more convenient and accurate, plus they significantly reduce time costs. In addition, the formed edges of the products are distinguished by a flat surface.

Now a completely fair question arises, how to cut silicate or fireclay bricks. Modern specialists in the construction industry use the following tools for this purpose:

machine for processing bricks;
special saw (petrol cutter);
Bulgarian.

How to cut bricks

When processing these building materials, you will need a pencil and a corner, in addition to the main cutting element. It should be noted that this procedure is accompanied by the formation of a significant amount of dust, so it is extremely important to use personal protective equipment. The respiratory tract should be protected with a respiratory mask, eyes with goggles, and hands with gloves.

For more accurate cutting of building materials, it is necessary to first apply markings on its surface. For this, a construction pencil is used. Now you can start cutting, and you need to do this not along the line itself, but near it, otherwise the brick fragment will turn out to be not as large as required.

Using an angle grinder

Now let's talk about how to properly cut a brick with a grinder. This operation is carried out when it is required to produce a small number of fragments of building materials. For processing, models that can be equipped with a circle with a diameter of 23 centimeters are suitable.

Smaller cutting elements can also be used, but in this case, productivity and accuracy of work suffer, since the disk will not pass through the entire thickness of the product, so the workpiece will have to be turned over.

The power of the tool used must be at least 2000 watts. You should not use too powerful a tool for this purpose, as it will be unnecessarily heavy and bulky.
