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 tool spindles with powerful and electronically synchronized 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 2x48 tool pockets to locate the reversible cutting inserts ensures high flexibility and long tool life due to the use of sister tools.
2 symmetrical, temperature controlled motor spindle drives with excellent power and torque parameters
Rapid positioning of cutting tools by means of highly dynamic rotary axes
Simultaneous operation of both tool disks with independent feed rates
Adaptable clamping solutions with shaft chucks to machine flange and post in one setup
Semi-automatic tool clamping, automatic transfer of pre-set tool data via ID-chip
