GRINDING MACHINE FOR BEARING RINGS AND METHOD FOR ADJUSTING SUCH A MACHINE

摘要

A grinding machine for bearing rings, the machine includes a frame, a rotating grinding wheel movable in rotation around a first rotation axis, a working station where a bearing ring stands during a grinding operation of one of its surfaces and holding means for holding a bearing ring in the working station, these holding means being rotatable around a second rotation axis and supported by a support plate movable with respect to the frame. The machine includes a first electric actuator for moving the support plate in rotation with respect to the frame, around a third axis perpendicular to the first and second rotation axes and a second electric actuator for moving the holding means in translation along the second rotation axis.
