Abstract:
1. A grinding machine for double-sided grinding of a tooth flank on a hard-metal tipped circular saw blade, comprising: two grinding units, each with a grinding body; a first drive to move at least one of the two grinding units along a first axis running perpendicular to a plane containting the saw blade; a second drive to move at least one of the two grinding units along a second axis running parallel to axes of rotation of the grinding bodies; a third drive to move at least one of the two grinding units along a third axis running perpendicular to the first and the second axes; and a joint control unit for coordinating the movements of the grinding units along the second and the third axes in such a way that during grinding of a tooth a tangential clearance angle of the tooth flank is variable along the second axis.
