Grinding machine for double-sided grinding of saw tooth edges

A method for controlling a grinding machine having two grinding units, each grinding unit having a grinding body and each grinding body having an axis of rotation, comprising:

• moving at least one of the two grinding units along a first axis running perpendicular to a plane for containing a saw blade, the saw blade having a tooth and the tooth having a flank;
• moving at least one of the two grinding units along a second axis running parallel to at least one of the axes of rotation of the grinding bodies;
• moving at least one of the two grinding units along a third axis running perpendicular to the first and the second axes;
• and
• coordinating the movements of the two grinding units along the second and the third axes in such a way that during grinding of the tooth, a tangential clearance angle of the tooth flank is variable along the second axis.

• and
• varying a tangential clearance angle along the tooth flank of the saw blade in such a way that the offset of one of the grinding bodies along the third axis is of varying size for different points on the tooth flank along the second axis.
