Additional Information:

The combined CNC hobbing and worm milling machine KOEPFER MZ 120 is characterized by its flexible applicability and is used for small module applications. By simply swiveling the milling spindle from the horizontal to the vertical position and selecting the corresponding operating mode on the CNC controller, the machine switches between worm milling and gear hobbing.
