A FANUC 31i-B CNC control and a PC-based control (NT-IPS) provides a high-speed programmable machine controller for faster processing and several features for increased efficiency and maintainability. New standard functions include a spindle speed override switch, a program number search, C-axis synchronization and helical interpolation (for Y-axis models).


In addition, the distance between the spindles has been increased to 31.5" (800mm) while still providing the same compact machine footprint of 67.8 ft² x 6.2 ft (6.3m² x 1.9m). Also, with a maximum tool swing of 23" (570mm) on the upper and lower turrets, users can drill through a 2" (51mm) bar diameter from one side on the Nakamura WT-150 II.


The spindle motor features increased torque for greater speed, and the S3 rate is now available for high torque. Faster feed is provided via a rapid traverse of 787 ipm on the X-axis, and cutting feeds of 314 ipm on the X, Z, and B axes.


With simultaneous 4+4 axis control, the WT-150 II offers 8-axis machining capability. The system includes 12 station upper and lower turrets with a half-index capability, to hold a total of 48 tools for multiple processes. A left and right spindle with speeds up to 5,000 RPM at 20 / 15 HP, and a 6 inch (150 mm) chuck and 2 inch (51 mm) bar capacity are provided. The WT-150 II is capable of 7.5 HP milling capacity on the C-axis.
