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, said thrust spindle being displaceable in a selective strokin g and superimposed rotary motion, whereby the stroke position can be detected by a first measuring device arranged in the stroke drive. According to the invention, the superimposed rotary motion of the thrust spindle is produced via a direc t rotary drive and there is arranged in the area of the thrust spindle a secon d measuring device for the detection of errors in its movement path. The invention further relates to a method for the operation of the aforementioned gear shaping machine. |
