GRINDING WHEEL Russian patent published in 2018 - IPC B24D5/00 B23F21/02 B23F19/00 

FIELD: technological processes.

SUBSTANCE: discontinuous working surface of the grinding wheel has a regular profile, for example the thread profile. The working surface of the grinding wheel includes an even number of sections. Each of them is profiled with a pitch equal to the profile pitch of the grinding workpiece, with the profile threads remote next by one and with the forming surface between the remaining threads in the form of a straight line connecting the bases of the threads. The section profiles are offset relative to each other. The sections of the grinding wheel consist of two segments, the abrasive material of which has a different seediness. Large-grained segments produce preliminary grinding, and small-grained segments - the final grinding of the workpiece.

EFFECT: improved quality and productivity of the thread grinding.
