The NILES-SIMMONS crankshaft turn-broaching machines N20 TB and N30 TB are based on the modular building-block system of the N-series. Two symmetrically arranged workpiece spindles with powerful, electronically synchronised spindle drives and two mirror imaged broaching units with highly dynamic rotary axes to locate the tool discs ensure efficient turning and turn-broaching operations on crankshaft bearings and other concentric features of crankshafts. The use of maximum 2×48 tool cartridges to locate the reversible cutting inserts ensures high flexibility and long tool life owing to the use of sister tools.
The benefits at a glance:
- 2 symmetrical, temperature-controlled motor spindle drives with high output parameters and torque parameters
- Fast positioning of the cutting tools using highly dynamic rotary axes
- Simultaneous operating of both tool discs using independent feed rates
- Adapted clamping solutions using shaft clamping sets for machining the flange and journal in one setting
- Semi-automatic tool clamping, tool data can be automatically transferred using an ID chip
