Eight-Axis Multitasking Turning Center

Methods Machine Tools Inc. has introduced the Nakamura-Tome WT-150 II eight-axis, multitasking turning center.

Methods Machine Tools Inc. has introduced the Nakamura-Tome WT-150 II eight-axis, multitasking turning center. The turning center, which features numerous upgrades from the base WT-150 design, has opposed twin-spindle, two-turret construction, offering high-speed and high rigidity in a compact machine.
 
For ease-of-operation, the WT-150 II features a 19" high-resolution, touchscreen LCD panel. 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. 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" (800 mm) while still providing the same compact machine footprint of 67.8 ft² × 6.2 ft. (6.3 m² × 1.9 m). Also, with a maximum tool swing of 23" (570 mm) on the upper and lower turrets, users can drill through a 2" (51-mm) bar diameter from one side on the Nakamura WT-150 II.
 
The spindle motor features increased torque for high 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 eight-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 as high as 5,000 rpm at 20/15 hp, and a 6” (150-mm) chuck and 2” (51-mm) bar capacity are provided. The WT-150 II is capable of 7.5-hp milling capacity on the C axis.   
 
The turning center features the latest Nakamura cover design with a large window, LED work light for maximum visibility and a lightweight door with maintenance equipment available in an arrangement at the front of the machine. CAMplete TruePath turn-mill software is standard on Nakamura-Tome multitasking turning centers.
