(Engineering), Professor, e-mail: korotkov.a.n@mail.ru Kuzbass State Technical University named after T.F. Gorbatchev, 28 Vesennaya st., Kemerovo, 650000, Russian Federation Abstract Grinding tools only partially utilize their potential cutting capabilities. Not all grains in the tools are actively involved in the overall cutting process. Each grain has its own arbitrary shape and chaotic location in the body of tools, which greatly reduces their performance. A new class of tools and technology for their production, which controls the shape and orientation of the grains used. The choice of a particular form of the grains is achieved by the separation of the source of abrasive mass vibration method. Grain orientation is ensured by applying an electrostatic effect that regulates the position of the grains in the instrument. Made an experimental batch grinding wheels (cutting, grinding, flap), as well as coated abrasives and tapes with controlled shape and orientation of grains. The tools are tested in the work and showed significant advantages compared to standard tools. Keywords shape of grains, orientation of grains, control of the shape and grain orientation, cutting, grinding, flap wheels, grinding tape and sandpaper, comparative tests
