ABSTRACT:
A grinding machine (10) for double-sided grinding of tooth flanks, in particular hard-metal tipped circular saw blades (14) is described. The grinding machine comprises two grinding units (16, 18) each with a grinding body, a first drive to move at least one of the two grinding units (16, 18) along a first axis (x1, x2) running perpendicular to a plane containing the saw blade (14) and also a second drive (36) to move at least one of the two grinding units (16, 18) along a second axis (z) running parallel to axes of rotation of the grinding bodies. Furthermore a third drive (38) is provided to move at least one of the two grinding units (16, 18) along a third axis (y) running parallel to the first (x1, x2) and the second (y) axis. A control method according to the invention for the grinding machine (10) provides that a tangential clearance angle of a tooth is varied along a tooth flank during the grinding of the tooth.
