Method and apparatus using abrasive belt for superfinishing workpiece bearing surfaces, in particular for the superfinishing of cam surface on a camshaft

摘要

In order to machine a part (1), having a rotational axis, of a non-cylindrical bearing surface (2), two portions of the same abrasive band (14) which are spaced from each other in the band longitudinal direction are applied. This is done by means of two independent support parts (12) activated by two actuators (8) mounted on a common support (4), along two contact zones angularly spaced around the part rotational axis against the bearing surface. An Independent claim is included for a machining device.
