Additional information
The combined CNC hobbing and worm milling machine KOEPFER MZ 120 is characterized by its flexible usability and is applied in the small module range. Simply by swiveling the milling spindle from the horizontal to the vertical position and selecting the respective operating mode on the CNC control, the machine can be switched from a worm milling machine to a hobbing machine and vice versa.

CNC control Fanuc 18i-MB (conversational/ISO)
