In the event that the repair project provides a wider window opening or uniting the loggia zone from the living room, the wall cutting is required. You should choose the most suitable method for this and the tool. About how to cut the walls without dust and quickly, will be told in the article.

Overview of wall cutting tools

Cut the stone or brick can be as follows:

• bulgarian with a stone disk or with diamond spraying;
• petition (convenient if it is impossible to connect to the power grid);
• laser equipment;
• a clinker machine (for walls is not used);
• shludd;
• diamond string (cable cutting);
• stensevel machine;
• drill machine (for openings).

Cutting walls Bulgarian

This universal tool can be used for cutting metal, ceramics, concrete and stone. The cutting part serves as a cutting wheel, the form of which is selected depending on the material being processed. For cutting wall, a circle is suitable with a diamond spraying: unlike abrasive, its service life is longer.

Not thick interior partitions can be cut by a grinder

Note: Abrasive circles can be used to cut walls isolated from foam concrete or thin brick walls (in Pollipich).

Diamond cutting of walls with their own hands is performed in stages.

1. Marking of the opening: With the help of roulette, line, plumb, level and chalk on the wall, lines corresponding to its size and shape. It is necessary to consider the dimensions of the door box or window frame.
2. A cutting disc is installed: for cutting the wall used the largest, diameter of 230 mm. Bulgarian must be equipped with a protective shield that protects a person from fragments. Additional protection of the eyes and respiratory organs (glasses, respirator) is necessary. Works should be carried out in mittens.
3. With a moderate pressure on the tool, we carry out the disk perpendicular to the plane of the wall along the cut line. The launch of the grinding circle must be completed before the wall touching them. If the opening is too big that it may make it difficult to disassemble the wall fragment, it must be divided into fragments.
4. The refinement of the edge edge is carried out with a grinder with a circle of smaller diameter - 125 mm.

Tip: If the wall is the thickness of the cutting circle, it is recommended to cut it on both sides. In order to accurately apply marking, it is necessary to drill the wall in several places along the line of the cut (including the corners). Holes will serve as benchmarks on the reverse side.

Preparation for diamond cutting wall includes a selection of a cutting circle for a grinder. The edge form distinguishes the following types of cutting circles.

1. With a solid edge. Such discs differ in low cost, with their help you can get a smooth slice. Disadvantage - short service life: The solid edge does not provide ventilation, which becomes the cause of overheating of sputtering and its destruction.
2. With segmented edge: The cutting portion is separated by radial ventilation cuts. Such a structure contributes to the cooling of the working part of the disk, which extends its service life. The disc is not designed to cut a water-cooled brick. Diamond cutting of the brick wall passes with the formation of abundant dust and fragments that will fill the cuts, worsening the result of the work.
3. With a turbocked (gear) edge: the form of the cutting part increases the efficiency of the disk. Can be used for cutting with water supply. Such discs are characterized by high strength.

Work on cutting walls by gas

The tool power allows cutting thick walls from concrete or stone blocks. The cutting part serves a large diameter of a diamond spraying or chain. The instructions for diamond cutting of the walls are not different from the description of the working technology of the grinder.

The bulbes are more convenient in operation than the stone machine: due to its compactness, the tool can be used in a limited space. Dust as a result of cutting is not formed, due to water supply.

Using a wall-cutting machine for cutting walls

Fast diamond cutting walls with reinforcement is performed using a wall-cutting machine. High power capacity (up to 20 kW) limits its use in the premises. Operactions for windows and doors cut out from the outside during the reconstruction of the building.

Cable cutting walls

Diamond cutting of a concrete wall, the thickness of which exceeds the radius of the tool disks, is performed. This method speeds up the work, allows you to obtain an accurate line of the cut (the deviation does not exceed 3 mm) and a flat surface.

Applying a shluder for cutting walls

The swordzer is a disk machine, the use of which is limited by horizontal surfaces. The swordzer is used if the reconstruction project is provided by the opening in the ceiling. The maximum depth was cut - 320 mm.

Shvondurchik is different:

• high reliability;
• ease of control;
• low cost performance;
• precision cutting and quality of the formed surface.

Advantages and features of wall cutting tool with diamond spraying

Laser cutting is performed using expensive equipment, which requires accounting for the following factors:

• the strength characteristics of the material being processed (brick, stone, block, concrete);
• wall thickness or overlap;
• features of the cut line;
• reinforcement method;
• the possibility of connecting the tool to the power grid;
• opportunities for using water supply for water supply to the place of work.

Diamond cutting allows you to get the edge with a high-quality surface

Diamond cutting of walls, compared with other methods, has a number of advantages.

1. The destruction of the wall is excluded: the operation of the tool does not create shocks and vibrations. This makes it possible to obtain the opening in the wall folded from low quality material.
2. During operation, less dust is formed (compared to other tools).
3. The noise level created by the cutting diamond instrument is significantly lower than when using a perforator or a jackhammer.
4. A diamond circle or string allows you to get the surface that you do not need to refine. For comparison: after the shock tool, an uneven edge remains.
5. Cutting accuracy: a smooth edge is formed, without chips, with the same slice angle throughout the perimeter of the opening.

Important: After the opening is cut, it must be increased by metal structures.
