EQUIPMENT FOR PRODUCING OF GRINDING WHEELS WITH CONTROLLED FORM AN ORIENTATION OF ABRASIVE GRAINS Korotkov V. A. 1, 2 Ph.D. (Engineering), Associate Professor, e-mail: korotkov-va@mail.ru Minkin E.

Gorbatchev, 28 Vesennaya st., Kemerovo, 650000, Russian Federation Abstract Standard grinding wheels using their operational capabilities only partially and this deficiency is largely linked to a lack of optimum geometry of the cutting elements of circles, that is abrasive grains which have uncontrolled form and a chaotic orientation in a tool body. The equipment for production of essentially new designs of grinding wheels with a controlled form and orientation of abrasive grains is considered (devices for the form separation of abrasive grains, mixing units, devices for orientation of grains, the equipment for pressing of grinding wheels, devices for heat treatment implementation). Thanks to it abrasive grains with fuller return start using the potential opportunities, thereby increasing operability of the tool in general. Keywords Grinding wheels, form parameter of abrasive grains, separation of abrasive grains, preparation of abrasive mixture, orientation of abrasive grains, pressing and hardening of grinding wheels
