PROCESS OF FINISHING Russian patent published in 1996 - IPC

FIELD: mechanical engineering. SUBSTANCE: tool head is set at angle to part with crossing of their axes in plane of symmetry of worked profile. Tool head is set in rotation with which it describes cone relative to rotation axis of worked part. Vertex of cone matches symmetry center of worked part and angle of crossing of axes in space remains constant and is found from expression α = arctgL-K•B/D,, where L is width of abrasive sticks; B is length of projection of profile of worked surface on to part axis; D is diameter of worked surface; k is coefficient of overtravel of abrasive sticks equal to 0.9-1.0. EFFECT: improved efficiency of finishing operation. 2 dwg
