Without knowing the features of belt and eccentric sanders, it is difficult to make the right choice of technology. Equipment performance and performance are critical to successful operation. Before choosing pneumatic and vibration machines for working on wood and concrete, metal and stone, you should carefully study their capabilities, operational requirements. It is important to remember that ordinary household models are not designed for continuous continuous operation. If you have to use the grinder regularly and for a long time, you should choose the version for professional use.

The equipment performs polishing, grinding of metal, plastic, wood, concrete, stone, allows you to achieve the desired level of smoothness, remove the old coating, prepare the material for decorative coating. The working part of the equipment is a disk or tape-type plate that rotates at a certain frequency.

All variants of grinders presented in the model range of Makita equipment are divided into the following types:

• corner;
• vibrating;
• flat (deltoid, tape, eccentric);
• brush.

Surface grinding techniques are considered the most popular. This type of power tool adheres to the working surface completely, with the entire rotating platform. Eccentric models are equipped with disc nozzles. Deltoids are similar to irons, are made in a compact size range, and are used in the treatment of difficult, hard-to-reach areas. Small area triangular sole is comfortable and functional, suitable for home workshop use.

The belt is stretched over two rollers and moves along a straight path. This approach provides opportunities for successful processing of a large surface area, the platform itself can also be large. Belt sander machines are used for scraping parquet and maintaining wood floors. A grinder or grinder, in addition to direct grinding, can be used in conjunction with cutting wheels to perform a wide range of operations. As a rule, it is used for mechanical processing of surfaces located in a vertical plane.

Vibration models of Makita grinders deserve special attention. They use grinding mechanisms that generate vibration vibrations with a low amplitude. The frequency of movements reaches 20,000 per minute. Machines of this type are considered industrial or professional because their performance allows them to quickly process a large area of ​​coverage. Woodworking has its own subtleties.Coarse grinding is convenient to carry out using brush machines with a cylindrical working platform. For grinding on metal, such a tool is not used due to the too low intensity of the impact.
