Additional information:

The combined CNC hobbing and worm milling machine KOEPFER MZ 120 stands out for its flexible application and is used for small module production. By simply swiveling the milling spindle from the horizontal to the vertical position and selecting the corresponding operation mode on the CNC control, the machine converts from a worm milling machine to a gear hobbing machine and vice versa.
