Patent ID: 8732937

Claim:
An apparatus for cutting gear teeth in workpieces, the apparatus comprising: a machine base body, a first tool spindle that is associated with the machine base body and that has a roughing tool having roughing teeth, a second tool spindle that is associated with the machine base body and that has a roller compression tool that is combined with a deburring wheel, a smoothing tool having smoothing teeth, which is accommodated either by a third tool spindle that is associated with the machine base body or by the first tool spindle, and a workpiece spindle for accommodating a workpiece, wherein tooth height of the roughing teeth of the roughing tool substantially corresponds to a target dimension of tooth gap depths of the gear teeth to be produced, but a width of the roughing teeth is narrower than a target width defined by spacing between tooth flanks of the tooth gap to be produced, wherein the compression teeth of the roller compression tool have at least one compression flank which produces a chamfer in the roughed gear teeth that is wider in a head region of a given one of the tooth flanks than in a base region of the one tooth flank, and wherein the smoothing teeth of the smoothing tool have a tooth height that is less than the tooth height of the roughing teeth, and have a tooth width that is greater than the tooth width of the roughing teeth, for producing the tooth gap at the target width.
