FINISHING METHOD Russian patent published in 1997 - IPC

FIELD: mechanical engineering. SUBSTANCE: method involves transmitting rotational motion to processable part and tool head with abrasive bars, with part and tool head rotating about their axes intersecting at an acute angle. Two surfaces are simultaneously worked by two rows of abrasive bars fixed in pairs within holders of tool head for self-positioning relative to surfaces in process, with intersection point of axes of rotation of part and tool head being positioned in plane of symmetry of processable surfaces. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 2 dwg
