At the moment, in the industrial sphere, special brushes in the form of disks and ends are actively used, the diameter of which ranges from 60-300 millimeters. Nevertheless, it is important to evaluate the level of efficiency of using such equipment, since without a certain practical experience, supported by theoretical knowledge, it will be difficult to cope with such tools independently. Disk wire brushes in cases of microscopic cutting are used, as one of the types of processing of finishing surfaces. In its design, such a tool consists of many smallest cutting particles that form the body of rotation, and all segments have the same length made of high -carbon steel.
