Diamonds in rims are used for straightening grinding wheels during internal and external round, flat, and chert-free grinding, as well as during tooth grinding, slot grinding, and other finishing operations on shaped surfaces.

Diamonds in the rims are used to correct grinding wheels of all characteristics used in the metalworking industry for final grinding in operations that achieve a roughness of at least 0.2 microns (incision grinding) and 0.1 microns (longitudinal grinding) of the machined surfaces of the part. at the same time, the top of the diamond should be 1-2 mm below the centerline.

Diamonds in the frames are made with a holder angle of a = 900 (for straightening shaped profile circles) and 1200 (for straightening straight profile circles).
