High-Performance Spindle with Two-Axis Tilting Head A/B Axis +/- 30 Degree
The spindle head is adapted with a direct drive, 8,000 RPM, 35 HP spindle that has a maximum torque of 811 ft-lb. The rugged five-axis, A and B head design allows for simple fi ve-axis programming. The Z axis incorporates a gas-over-oil counterbalance system for smooth positioning and cutting.
Advanced Control
The Fanuc 31i five-axis CNC delivers high-end features for a wide range of production and job shop environments. This powerful control allows for accurate cutting performance for even the most complex five-axis applications. With the UA2090Ti Series, smooth surface finishes and fast cycle times are possible using such features as AI Nano II and Smooth TCP.
