SECTIONAL GRINDING WHEEL Russian patent published in 2002 - IPC

FIELD: mechanical engineering; abrasive treatment of blanks. SUBSTANCE: sectional grinding wheel has metal body, change members made in form of polyhedral inserts and mechanism for securing these inserts; faces of polyhedral inserts which carry working abrasive layers have radius equal to radius of working surface of wheel. In butt of wheel there is circular slot with keyways made on cylindrical surface of smaller radius; change members are secured there by means of keys. Mounting surfaces form polyhedron; radius of faces of this polyhedron is equal to smaller radius of circular slot. Such construction makes it possible to adjust distance between change members carrying working layer made from supercharge abrasive material, thus extending technological capabilities of grinding wheel. EFFECT: extended capabilities. 5 dwg
