Methods Machine Tools, Inc., a leading supplier of innovative precision machine tools, has introduced the Nakamura-Tome WT-150 II 8-Axis, Multitasking Turning Center.  The WT-150 II, which features numerous upgrades from the base WT-150 design, has opposed twin-spindle, 2-turret construction, offering high-speed and high rigidity in a compact machine. 

“With the introduction of the WT-150 II, we are able to offer simplified operations and greater efficiency and speed on a powerful multitasking Nakamura machine”, said Mr. Richard Parenteau, Director of Application Development at Methods Machine Tools, Inc.

For ease-of-operation, the WT-150 II features a 19" high-resolution, touch screen 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.  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.    

The WT-150 II features the latest Nakamura cover design with a large window, LED work light for maximum visibility and a lightweight door with maintenance equipment conveniently available in an arrangement at the front of the machine.  CAMplete TruePath Turn / Mill software is standard on Nakamura-Tome Multitasking Turning Centers.  CAMplete Turn / Mill software is an integrated suite of G-Code editing, optimization, analysis and verification tools, enabling a full range of turn/ mill functions.
