Grinding machine for double-sided grinding of saw tooth edges

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...

Zusammenfassung:	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.
