Abstract
The invention relates to a gear shaping machine for the production, or more precisely machining, of gear wheels with a motor-driven rotatable machine table for holding the work-piece, a thrust spindle with a tool fixed thereto, preferably a cutting wheel, the thrust spindle being displaceable in a selective stroking and superimposed rotary motion, whereby the stroke position can be detected by a first measuring device arranged in the stroke drive, and to a method for the operation of the aforementioned gear shaping machine. The superimposed rotary motion of the thrust spindle is produced via a direct rotary drive and there is arranged in the area of the thrust spindle a second measuring device for the detection of errors in its movement path.

A gear shaping machine for the production of gear wheels with a motor-driven rotatable machine table for holding a work-piece, a thrust spindle with a tool fixed thereto, said thrust spindle being displaceable in a selective stroking and superimposed rotary motion, whereby a stroke position of the thrust spindle can be detected by a first measuring device arranged in a stroke drive, wherein the superimposed rotary motion of the thrust spindle is generated by a direct rotary drive motor and arranged in the area of the thrust spindle, a second measuring device for detecting deviations with respect to a preset movement path of the thrust spindle.
