Grinding machine for bearing rings and method for moving a bearing ring in such a machine

A method for moving a bearing ring between a loading station and an unloading station in a grinding machine provided with a grinding wheel rotatable around a first rotation axis, the method comprising steps of:

• a) picking the bearing ring with a multi-axis robot;
• b) moving the bearing ring with the multi-axis robot into a working station of the grinding machine;
• c) actuating holding subsystem for holding the bearing ring in the working station during grinding of a surface of the bearing ring;
• d) gripping the bearing ring in the working station via gripping feature provided on a moving arm using a translation movement of the arm along a second rotation axis parallel to the first rotation axis;
• e) deactivating the holding subsystem;
• f) rotating the moving arm around the second rotation axis in a direction that brings the bearing ring close to the unloading station;
• g) translating the moving arm along the second axis of rotation in a direction that frees the bearing ring from the gripping feature.
