Abstract
On account of the constructional form of the tool head ( ) according to the invention, the opposite sides ( ) of a tool ( ) attached to the tool spindle ( ) of a numerically controlled continuously generating gear grinding or hobbing machine are capable of machining the upper and lower sets of teeth ( ) of a double-sided face-gear ( ) in one and the same set-up and without disturbing the synchronization between the rotations of the grinding worm and workpiece maintained during the grinding of the first set of teeth, without risk of collision. This eliminates the need to reset the workpiece ( ) between the machining of the two sets of teeth ( ), thereby shortening the overall machining time substantially, and allowing the avoidance of accuracy losses due to the resetting of the workpiece ( ).
