Abrasive tool

Abrasive tools - Made from abrasive materials, intended for the machining of metal, leather, wood, glass, rocks, plastics, etc. By industrial methods, abrasive tools began to be produced in the 2nd half of the 19th century. (since the advent of grinding machines).

Abrasive tools are divided into 2 main types: hard (grinding wheels, heads, segments and bars) and flexible (grinding skin and products from it - tapes, discs, etc.). Grinding wheels or grinding heads, consist of grains of abrasive materials, bonded into one piece with any binder. They are made mainly from artificial and. in a small amount, from natural abrasive materials, mainly by pressing the mass, consisting of grinding grain and ligament, with subsequent thermal and mechanical processing of the obtained blanks. In addition, abrasive tools are produced by hot pressing, casting, casting under pressure, extrusion, etc. It is used for mechanical processing: grinding, grinding and more. Abrasive tools can be hard, for example, grinding wheels, bars, and soft, for example, grinding skins.
