CNC Facing and Centering Machines This is the NDM family of machines in an endmachining configuration for complex machining like facing (cross-milling), centering, drilling. threading, tapping, etc. for work pieces up to 80 mm dia. and 600 mm length (NZM 200) and up to 100 mm dia. and 3000 mm length (NZM 300). Modular design similar to Series NDM with unrestricted chip-fall and automatic chip-disposal. Robust hydraulic clamping fixture for long life cycle with modular jaws for quick conversion.
