A device for cutting bricks with your own hands. Cutting bricks manually and using tools. The process of cutting bricks on a machine

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, product fixation and cooling systems. This allows you to minimize the process of dust formation and the risk of brick chips getting on the operator. Almost all modern machines are multifunctional and compact, the scope of application is limited only by the high price. The minimum cost of devices for professional processing is 80,000 rubles.

Model range overview

The range of equipment for cutting bricks includes machines from domestic, German, Polish and Asian manufacturers. Cedima and Fubag (Germany), Diam (South Korea) have good reviews, Lebedyan (Russia) have acceptable reviews. All machines for cutting bricks differ in design features, amount of power consumption, type of fastening system, location of the electric drive, disk diameters and cutting depth.

1. Cedima stone-cutting machine CTS-57 G, Germany.

One of the most famous models from a trusted German manufacturer, in demand among companies with different volumes and areas of work. CTS-57 G Cedima is designed for high-precision cutting of building products: all types of bricks, including clinker, marble, natural stone, porcelain stoneware, ceramic tiles. The machine is multifunctional, it is recommended to choose it if continuous and intensive use is necessary (the engine is characterized by high performance). A bucket of water for cooling is located below the drive; its volume reaches 50 liters; dirty liquid is not returned to it immediately, but is drained into a settling bath.

The design advantage is the ability to move the side stop and the fixed pendulum cutting part; this design allows you to cut workpieces at an angle of 45°. The ability to cut wedge bricks on a machine and other products with a non-standard shape has been implemented. To change the operating mode, it is enough to change the diameter of the diamond disc, the maximum possible reaches 400 mm. Like many foreign companies, saws are not included in the basic kit; they must be purchased separately.

2. Diam SKH-600, South Korea.

A multifunctional, high-power model from a trusted manufacturer of brick cutting machines with an optimal price-quality ratio. It is recommended to choose it when you need to quickly process stone, and when replacing discs with diamond chips - wood or any other building material. But the main purpose of the Diam SKH-600 is cutting large blocks and durable thickened bricks. The quality and accuracy of cutting is achieved by using high-strength aluminum guides and steel bearings that ensure smooth movement of the support table.

This brick saw has a closed cooling system that includes a reliable water pump and adjustable jets. The advantages of this design include the possibility of stopping the water supply to the disk (the dry cutting function is available), the disadvantage is the reuse of water from the drain pan. To extend its service life, it is advisable to change it to a clean one as often as possible.

3. Lebedyan SKE 350/600, Russia.

A stone-cutting machine with an overhead engine, designed for professional cutting of brick, cinder blocks, porcelain stoneware, tiles, and hard rocks. It has a stable one-piece frame made of high-quality steel, designed for intense and significant loads. Structural advantages include the presence of a mobile table for feeding bricks and other blocks and an autonomous water cooling system with a reliable pump. The equipment is designed for long-term continuous operation, regardless of the workpiece material.

The cost of this brick machine is superior to foreign ones with similar power and the ability to cut at an angle at least twice as much. At the same time, the basic kit includes a diamond disk with a diameter of 350 mm, a guide and a mobile table; they do not need to be purchased separately. Reviews about the products are mostly positive, noting the high quality of metal structures and the absence of dust when cutting bricks and building blocks. The warranty period when purchased from the manufacturer is 1 year.

4. Fubag A 44/420M3F, Germany.

Professional pendulum machine with a rotating frame for cutting tiles and bricks. The equipment is valued for its high build quality, reliable design, ease of operation and security. Covering the disc with a special steel casing guarantees the safety of the work process: all cutting parts are closed, and crumbs do not fall on the user. The machine has a top-mounted engine and a movable carriage. The device operates from a 380 V network and requires grounding.

The manufacturer emphasizes that the main advantage of this machine is the high accuracy of cutting bricks and building products. It is possible to change discs to work with materials of different sizes and hardness and regulate the load. An important requirement for operating the equipment is the use of cutting saws in strict accordance with the instructions. The basic kit does not include a diamond blade; it and replacement elements must be purchased separately.

5. Sima Venus 150 Mekano, Spain.

Compact machine for use on various construction sites. If necessary, the model can be easily folded, transported and installed in a new location. The functionality is not inferior to other Sima series: the ability to cut at an angle and work with different building materials when changing discs is implemented. The mechanism for changing the cutting depth is simple: the workpiece is fixed on a long table, this design allows cutting blocks up to 1500 mm. The manufacturer's design advantages include a reliable electrical cable system.

Comparison of characteristics of the considered machines for cutting bricks

Tips for choosing equipment for cutting bricks

The main operating characteristics are the productivity 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 maximum permissible load value.
• Maximum diameter of the working disk, the ability to change the cutting depth (change cutting elements).
• Cutting error. It is noteworthy that most manufacturers indicate this ability as a basic ability, but numerical values ​​are difficult to find among publicly available information. The only way out is to buy proven brands.
• Possibility of cutting 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 will have to stop the workflow.
• Stability of the support table, evenness and smoothness of the guide structures.
• The presence of a removable or stationary metal casing to protect the machine operator (provided for in most modern devices).
• Dimensions and weight, ease of movement. The factor is in principle insignificant, but machines equipped with wheels are easier to transport.
• Availability of fans for additional cooling. This modification is definitely worth choosing for large volumes of work.
• Overheating control system.
• The warranty period specified by the manufacturer.

The cooling system of the machines deserves special mention. On the one hand, water supply allows you to extend the life of expensive discs. On the other hand, in most of even the most modern machines for cutting bricks 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 the closed-loop system to a continuous one.

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

You can cut brick yourself using hand-held power tools, special machines and installations. The choice of a suitable device depends on the volume and type of work.

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

List of tools suitable for cutting

Devices needed in the process of laying walls:

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

To make cuts in brickwork:

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

1. Angle grinder, grinder and circular saw.

For small volumes 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 come in two types:

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

Diamond blades for angle grinders come in four types:

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

When applying markings, take into account a margin of 1-2 mm for the displacement of the cutting element, otherwise there is a high risk of cutting off more than necessary. If you have no experience, then it is better to first try to process an old brick or a piece of a new one and adjust the size and direction of the indentation.

2. How to use an angle grinder correctly?

• Be sure to hold the angle grinder strictly at right angles to the surface.
• Place another block or a wooden block under the block to be processed.
• There is no need to put pressure on the tool during the process; its own weight is enough.
• If the diameter of the disk is not enough, then first cuts are made along the entire perimeter, then it is broken and the cut is processed.

If you need to make a cutout with a grinder in a brick wall, then it is correct to first apply markings. Then through holes are made with a hammer drill, after which the angle grinder is cut according to the markings.

A circular saw is most often used for woodworking, but stone circles are also available for sale. The circular machine 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. They cut smoothly, without jerking or pressure.

3. Petrol cutter.

This tool operates on the same principle as an angle grinder, but differs in its increased size, the presence of a very powerful gasoline engine, and the ability to 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 disc cutters, 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 yourself.

4. Stone cutting machine.

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

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

The 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 doing the cutting is facing the cutting disc and clearly sees the markings.

Work order:

• Apply markings to the brick.
• Fix it on the table.
• Bring the cutting disc to the place of the future cut.
• Connect the machine to the network.
• Select speed.
• Turn on the water supply.
• Cut off the marked part.

5. Wall cutting machine.

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

Characteristics:

• Type of drive. Available with electric or hydraulic drive. The former are quieter, hydraulic ones are more powerful, but require a large number of additional devices (a fluid reservoir), and in the event of a leak, they can cause damage to nearby devices.
• Engine power. The maximum cutting depth 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 hand-held 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 for working with thick walls.
• By type of cutting unit. There are disc and cable machines; in the former, cutting is carried out by rotating a diamond-coated circle, in the latter - by reciprocating movements of a 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 machines 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 disk equipment.

6. Laser installation.

The most modern method is the use of 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 processing;
• low noise level;
• the wall material is not deformed;
• ease of changing modes.

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

No construction can yet do without stone, brick and similar wall materials. Durability and availability make them the main and most reliable materials for the construction of walls, stoves, fences and paving sidewalks and paths. In the process of laying bricks, sometimes emergency situations occur 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 high-quality fit of the block in place.

Working principle of brick cutting machine

The most effective method of cutting brick remains cutting using a machine. And 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 look at later. Brick cutting machines, like any tool, can be either for industrial purposes or designed for use at the household level. We will not consider equipment for sawing stone blocks from rock, just as we will leave machines for jewelry work outside the scope of the review.

A machine of any level of complexity consists of a strong and reliable frame, a cutting element, a drive system and a control and starting system. This sounds too loud for the simplest cutters, however, without these elements we will not cut any brick. To fully control 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

As an example, we can cite a universal-purpose machine. It is not very large to be included in the industrial category, and can just meet the needs of low-rise construction. The universal device BALI MEKANO fits into the average price category. A machine for cutting bricks, 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 adjustments, so it can handle not only bricks, but also thermal clay and recycled concrete. There are no difficulties in working with standard materials, including brick. The maximum cutting height is 200 mm in one pass. The machine can use diamond discs with a diameter of 400, 450 and 500 mm, and it can be connected to a regular 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 capabilities of cutting tools have expanded significantly, and wheels for working with stone have become not a rare occurrence. A diamond blade consists of a metal core and a crown, onto which diamond chips are applied. There are four methods for making cutting discs. Both the disk resource and performance depend on the manufacturing method.

1. The galvanic method involves placing the edge in an electrolyte containing artificial diamonds. Such discs have good cutting ability, but have a short service life.
2. 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 cannot be relied upon for long-term use.
3. Hot pressing. A similar technology, only during pressing the temperature of the press is increased. The discs are the most durable of all of these, but the cutting capabilities of the edge are somewhat inferior to cold-pressed discs.

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

Cutting bricks with a grinder

Naturally, not everyone can afford to have a brick cutting machine on their farm, so there is an alternative processing method - an angle grinder or grinder. To do this, you will 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 disk simply will not be able to cut the brick to its full thickness, so you have to turn it over, which is a waste of time, and the quality of the cutting will suffer.

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

There is no material that cannot be processed. Everything is processed, so even if you don’t have a machine for cutting bricks, you shouldn’t despair. The grinder will save the situation, and the masonry will turn out smooth and neat.

A brick cutting machine greatly facilitates and speeds up construction work that requires the use of special devices. The tool is lightweight and convenient, so even a beginner can handle it. This small-sized equipment provides fast, convenient and safe cutting of brick, concrete, ceramics, artificial stone, etc.

When making brickwork, it is not always possible to use a whole brick, since there are areas where it will not fit completely. The material will begin to violate the integrity of the structure, falling out of its appearance. The one-piece element is suitable only for monolithic, flat surfaces that are durable and reliable.

Problem areas of a brick wall are various transitions and corners, as well as many other elements. To complete all the work correctly, it is necessary to cut the brick. For many years it was done by hand, but modern devices that allow sawing stone or brick greatly simplify human labor.

Widely used specialized machines from well-known manufacturers make it possible to give various materials the required shape. Cutting bricks with a grinder is no longer so popular. The design of the device consists of the following elements:

• drive motor;
• special table for cutting material;
• installation legs or racks for fixation;
• steel frame with a disk for cutting bricks;
• water container for the irrigation system to minimize the volume of dust.

Some home craftsmen have learned to make brick cutting machines with their own hands. In any case, it is more profitable to purchase professional equipment, since it will serve for many years. In general, the structure of the entire structure is not particularly complex, but it greatly simplifies the construction work of laying building materials with your own hands. The cutting element of the machine is a diamond disc having a certain diameter. It must be of high quality so that all masonry work is carried out at the proper level.

Technical characteristics of the cutting machine

Proper use of the brick cutting device greatly increases the service life of this tool. It can be easily placed in a car, and transporting the machine does not cause much trouble. This is important not only for professionals, but also for beginners. The machine can be transported to any construction site.

Tests and testing of tools assembled at the factory make it possible to identify defects at the manufacturing stage of the machines. The results obtained allow us to judge the quality of the device, the performance of which must correspond to the declared parameters.

Slicing machines have the following capabilities:

• perform 2 types of cutting: wet and dry;
• the seams between the bricks are invisible;
• work is performed at high speed.

Tools for cutting bricks of domestic and foreign production are supplied to the market. High precision equipment using the latest technologies is used to manufacture machines. If the quality level of the tool is appropriate, then it can rightfully be called world-standard equipment.

Modern machines for cutting bricks are divided into household and industrial devices. They have standard sizes and power. Thanks to their guaranteed performance, they can be used in small industrial enterprises, including private construction sites.

Industrial types of equipment that allow cutting bricks are installed in large factories that produce products in large volumes. Such devices have a large number of functions that allow high-quality processing of building materials. The main technical characteristics of the models are:

• voltage 220-380 V;
• power 2.2-3.0 kW;
• cutting depth 65-200 mm;
• cutting length 500-620 mm;
• cutting disc diameter 300-620 mm;
• equipment length 950-1225 mm;
• machine height 1110-1370 mm;
• device width 615-720 mm;
• machine weight 57-109 kg.

You should choose a device for sawing stone or brick taking into account its power, operating mode, and equipment manufacturer. Devices from unknown or little-known manufacturers can lead to manufacturing defects or unit failure.

How to use the cutting machine

Working with the equipment is quite simple. To do this, you need to prepare a workplace, assemble and install the machine. Before sawing a brick wall or individual elements of building material, it is necessary to mark the surface that requires processing.

To install the work surface before cutting, it must be secured at the desired angle. After this, a cutting circle is brought to the marked area. Next, you can turn on the power, select the rotation speed of the diamond disk, as a result of which the brick should be cut smoothly.

Despite the fact that a device for cutting bricks has many advantages, it will not always be advisable to use it. Its cost is quite high, so cutting material in small quantities is best left to a grinder or circular saw. It is better to cut fireclay bricks with a special gas cutter. It is recommended to purchase machines for specialists who constantly perform similar work in large volumes.

A stationary machine that allows processing of building materials is an alternative to a grinder used for cutting fireclay bricks or facing stones. Any devices for processing workpieces must be supplied to the market with instructions. Work on the machine is carried out in stages:

• the workpiece is marked;
• the product is installed at the required angle;
• the circle of the device moves towards the workplace;
• the engine is turned on, the rotation speed is selected;
• the cutting element is set into rapid motion and the cutting process is carried out.

can be cut using a machine equipped with a segmented diamond blade. The main advantage when working with a brick processing machine is that the craftsman needs to be in a position that allows him to closely observe the cutting process. The material must be processed correctly, so the accuracy and quality of the work must be constantly monitored.

Precautions when cutting on the machine

When choosing what to cut silicate or, you should not forget about safety precautions for working with various types of tools. Special care must be taken when servicing precision construction equipment.

Compliance with safety regulations requires the use of discs of a certain model that corresponds specifically to this cutting element. Work should only be carried out when the equipment is reliably grounded. To avoid possible injuries, the following rules must be observed:

1. Maintain a stable position.
2. Do not use a facing brick cutting machine when processing wood.
3. Use personal protective equipment for vision, breathing and hearing (carry a respirator, headphones, glasses, etc.).
4. Do not use a partially disassembled device, do not use an old unit without insulation or without grounding.
5. Cut facing bricks using suitable diamond blades of the highest quality.
6. Do not use the device if there is a water source nearby where moisture comes from.
7. Do not suspend the cutting device. Even if it is a homemade machine.
8. Before work, ventilate the room well.

The market offers a large selection of brick cutting equipment. The cost of machines varies. Choosing it is a responsible matter, so you should not save money when purchasing a device. It is better to buy a high-quality machine with a guaranteed service life.

A brick cutting machine is a fairly new piece of equipment. With its help, you can easily cut stone without much effort.

When cutting bricks, do not forget about safety precautions. Be sure to wear safety glasses.

Types of stone cutting machines

Brick cutting machines are divided into various types. Thus, there are double-head and single-head machines, stationary and manual, with mechanical or pneumatic clamping, with and without a cooling system.

The cutting machine consists of a bed, a cutting element, a brick feeding system and a process control system. The cutting element is a circular saw and chain, which are powered by an electric motor. To perform loading and unloading operations, special loading rings are used.

Since brick is highly durable, the machine must be durable and reliable. And for its production, high-strength metal is used: steel or cast iron of special grades. They allow the process to be carried out efficiently, provide reliable control, and absorb vibration during operation. Brick cutting machines can operate on 220V or 380V. The first option is more common and is used in small workshops and households. The second option is more powerful equipment, used for mass work.

The machines are widely used in country or rural construction, for interior finishing work, and in the construction of brick kilns. Using the equipment, it is possible to perform cutting with high speed and accuracy. The evenness and precision of the cut allows you to obtain an even seam between the joining surfaces. Cutting bricks on the machine has a high degree of operator safety.

Selecting a cutting machine

If you decide to buy a cutting machine with your own hands, then you should know about its technical characteristics. The main parameters are power, diameter of working discs, length, depth and cutting angle. You should also pay attention to the error characterizing the accuracy and quality of the cut, and the combination of possible shapes. Almost all modern models can cut brick at an angle of up to 45 degrees.

The advantages of using a machine for cutting bricks: high speed, precision cutting, minimal amount of dust. Cons: relatively high cost of the machine.

It is necessary to pay attention to the volume of the coolant container. If such a container is very small, then you will have to constantly add liquid. And this requires additional time, you will have to be constantly distracted. It is very uncomfortable. For ease of movement of the machine, it is equipped with wheels. However, some models may be without them. You should pay attention to this.

An important factor is the manufacturer. Equipment from European manufacturers is of high quality. Some Chinese models also boast good quality and low prices.

Cutting brick requires a very strong cutting tool, stronger than stone. These can be diamond, topaz or other corundum discs. The invention of synthetic diamonds has made diamond discs much more affordable and can be purchased by a wider range of consumers. Diamond wheels can be produced by various methods. The manufacturing method affects the durability and quality of the cutting tool. There are the following methods for producing discs:

1. Galvanic. Disks have high performance, low cost, but at the same time a short service life.
2. Cold pressing (sintering). The resulting tool is characterized by low cost and short service life.
3. Hot pressing. The result is a highly durable blade with a long service life, but its cutting properties are not as good.
4. Silver soldering. The most effective method. As a result, diamond blades are characterized by high strength, performance and long service life. The only drawback is low resistance to high temperatures, so liquid cooling must be used.
