Additional information:
The combined CNC hobbing and worm milling machine KOEPFER MZ 120 is distinguished by its flexible applicability and is used for small module applications. Only by swiveling the milling spindle from horizontal to vertical position and selecting the corresponding operating mode on the CNC control, the worm milling machine is converted into a hobbing machine and vice versa.

CNC Control Fanuc 18i-MB (Dialog/ISO)
