Abstract
A method and a machine for the discontinuous generating grinding with indexing of the tooth flanks (14) of gears. The rotating grinding wheel (T) carries out several back and forth feed movements (X) from one axial side face of a tooth to the other. The gear (W) is rotated a small amount (rolling step s) at each change of direction point and the grinding wheel (T) is adjusted in the axial direction (rolling stroke .DELTA.Z). To produce corrections on the tooth flank (14), the grinding wheel can, during the feed movements (X), carry out additional lifting movements (.DELTA.K) in direction of the rolling stroke (.DELTA.Z).
