FIELD: the invention refers to the field of abrasive processing.
SUBSTANCE: it may be used at manufacturing of abrasive circles for effective roughing finishing and finishing treatment of half-finished products of the parts of machines and instruments. The abrasive circle has a body and elements with coarse-grade and fine-grained abrasive layers. Tetrahedral interchangeable elements are envisaged on the periphery of the body. Abrasive layers of different grain are fastened on the edges of the interchangeable elements. The last have possibility for turning at an angle of 900 relatively to axles installed in the radial openings of the body.
EFFECT: this construction is simple in manufacturing and allows in series to execute preliminary and final working of half-finished products on a one machine with a circle with interrupted working surface.
