Modern construction or reconstruction of buildings is performed using concrete, concrete blocks and bricks. Often there is a need to cut the listed building materials. Only so you can get a window or doorway. Best of all with this task, equipment for diamond cutting walls is coping.

What is diamond cutting
Diamond cutting wall is to drink it fragment or drill holes using a tool equipped with a cutting part with a diamond coating. Due to the high hardness, the diamond is not destroyed during operation.
Important: During diamond cutting, shock and vibration tools are not applied. Diamond is detrimental, and therefore the tool can come into disrepair.
Cutting walls with their own hands is performed in two ways:
- manually (without the use of pneumatic and power tools);
- with the help of a special unit.
In addition, cutting can be performed with fluid feed and without it. The liquid is necessary for cooling the cutting edge (which extends the service life of the tool) and preventing dust formation.
In which cases is applied diamond cutting
The use of diamond cutting tools is necessary in the following cases:
- expansion of doorways;
- the formation of new window and doorways;
- redevelopment of premises;
- device of inter-storey transitions;
- launching ventilation channels, boxes for wiring and other engineering communications through the walls;
- pruning protrusions and defects of the casting of concrete slabs;
- dismantling loggias and balconies.
Advantages of diamond cutting
Diamond cutting of walls with their own hands has advantages compared to other methods of processing building materials.
- The perfectly smooth plane of the slice that does not require additional processing.
- The walls of any thickness can be cut.
- Lack of vibration and minimum dust formed during cutting.
- The possibility of performing work in the shortest possible time.
- Security.
- The possibility of cutting in the horizontal and vertical plane at any angle.
- Processing of materials of any hardness.
- The ability to perform work in a small place, thanks to the compactness of the equipment.
- The ability to automate the process.
- Comparatively low cost of work.
Applied tools for diamond cutting
Depending on the complexity and volumes of work for cutting walls, various tools are used.
- Electric cutter (Bulgarian, equipped with diamond spraying disc). This is a hand tool to work in premises without artificial and natural ventilation. With the help of a carver, you can cut through the opening in the wall with a thickness of up to 250 mm, if there is access to two sides and in the absence of access - up to 125 mm. To protect against dust, a jet of water is used, which is directed to the place of operation of the instrument or use an industrial vacuum cleaner. The electrical cutter can serve as an alternative to the fuel in the case when the use of the latter is impossible. To cut thin (up to 100 mm) interior concrete partitions, a segmented or combined cutting disk is used.
- Power cutters. Cutting part of the tool is a disk with diamond-coated. Disc diameter - 400 mm. The thickness of a wall in which an opening can be made - from 150 to 300 mm (operating on one or two sides, respectively). Power cutters are used when there is no possibility to connect the equipment to the mains. During the cutting disk is organized water supply. Work is carried out in a ventilated room.
- Manual Chain Saw. Bus length leads to a maximum cutting depth of 500 mm. Using the saw is associated with considerable costs of physical energy.
- Wall saw. The unit is a mechanism acting through electricity or hydraulics. A distinctive feature of the machine is a large cutting depth - 1500 mm or more. Cutting of the wall may be formed at an angle in the vertical and horizontal mode. A disadvantage of such equipment - the ability to use a stationary mode (low mobility). Tool necessarily cooled with water.
- Machines for cutting the cable. With the help of a rope with special inserts equipment can cut large amounts of concrete. In the preparatory stage for the processed object throws the loop of the rope, which is then stretched and scrolled with the simultaneous supply of water. The result is a sectional view. The machine operates on three-phase 380 V.
- Joint cutter. Used for cutting horizontally disposed plates. The average depth of cut - 620 mm. The equipment can be used for the device interfloor transitions.
- Machine for diamond drilling. The equipment provides a round hole in the wall for ventilation ducts device or pads other communications. The machine is equipped with means for a fixed installation.
of diamond cutting guide
The technology of diamond cutting walls with gasoline cutters or hand power tool involves the following rules.
- Preparing walls for cutting with diamond tools. At this stage the markup wall on which a marker with the level and roulette denote contour future opening. If the thickness of the wall requires the use of cutting tools from two sides - the markup is also performed on both sides. In order to exactly match the markings in the corners of the door or window openings are drilled through holes.
- The petrocheus or grinder with a diamond cutting disk was made by the markup line. To avoid overheating and destruction of the diamond spraying of the Bulgarian disk in one pass, it should be cut into a depth of no more than 20 mm, interrupting every 1.5 minutes for cooling the tool. During cooling, the Bulgarian should work in idle mode. For better cooling to the place of cutting, water is supplied.
- The opening of a large size for the convenience of dismantling and security is divided into several parts, for which additional saws are made.
- After dismantling fragments of the wall, the defects of the opening are eliminated by grinding.
- Before you can cut the walls, you need to take care of the availability of means of protection. Work is performed in special glasses, gloves in headphones and with a respirator.
Important: Before cutting a brick wall, the opening is strengthened at the top with the help of channels, metal corners or heated beams. Metal design is connected by screws and welding.
