Abstract
A device has a work piece spindle for accommodating a bevel gear work piece, a tool spindle for accommodating a grinding wheel having an abrasive surface, and a plurality of drives for machining the bevel gear work piece. During machining of the bevel gear work piece, the grinding wheel rotates about the rotational axis of the tool spindle and engages the bevel gear work piece to remove material. The rotation is superimposed with an eccentric movement such that the grinding wheel only engages the bevel gear work piece at n contact regions of the abrasive surface. The device is configured to allow adjustment of the eccentric movement after a first machining phase and to specify m contact regions of the abrasive surface in a further machining pase, wherein the m contact regions do not overlap with the n contact regions.
