The NILES-SIMMONS crankshaft milling centres N20 CM and N30 CM are based on the modular building-block system of the N-series. Two symmetrically arranged workpiece spindles with electronically synchronised torque drives and two compact, powerful milling units ensure rough and finish milling operations on crankshaft main and pin bearing journals by means of these milling centres. The electronic linking and high-precision interpolation of the spindle tool system and special correction strategies allow the reliable production of high-precision bearing geometries.
The benefits at a glance:
- Reliable dry milling of bearing geometries, cheeks and counterweight contours and other concentric and eccentric features using one or two external cylindrical milling machines
- Customised clamping solutions with integrated or separate radial orientation of the workpieces
- Up to two NC positioned steady rests
- Semi-automatic tool clamping, tool data can be automatically transferred using an ID chip
