METHOD OF POLISHING Russian patent published in 2002 - IPC

FIELD: mechanical engineering, finishing abrasive treatment of surfaces of mechanism elements made from difficult to work materials. SUBSTANCE: workpiece is imparted in longitudinal feed, tool is imparted in rotation. Tool consists of disk made of grinding paper with abrasive grains of different size. Disk is mounted to the mandrel with an angle to the axis of rotation. The size of grains of the disk is smaller to its periphery. The disk is impregnated with cutting fluid. The nonworking surface of the disk is applied with bakelite varnish to make it more rigid. EFFECT: higher mobility of abrasive grains and quality of the surface. 1 dwg
