METHOD FOR WORKING SURFACE OF OPENINGS Russian patent published in 2002 - IPC

FIELD: machine engineering, namely, grinding surfaces of openings of machine parts. SUBSTANCE: method comprises steps of grinding openings of rotating parts by means of elastic tool whose outer surface is coated with layer of abrasive material. Tool has diameter more than that of ground opening and it is made of porous material impregnated with lubricating and cooling technological fluid. Before grinding tool is deformed in order to provide close contact and to supply fluid to grinding zone and it is imparted to reciprocation motion. EFFECT: improved conditions for microcutting, enhanced grinding quality. 1 dwg
