HIGH PERFORMANCE TURNING/MILLING CENTER WITH FASTEST CYCLE TIME IN THE INDUSTRY

Methods Machine Tools Inc. offers the Nakamura-Tome WY-250 Multi-Tasking Turning/Milling Center with unsurpassed milling capabilities. An opposed two-spindle, 2-turret construction features a unique upper and lower Y-axis capability for milling or drilling simultaneously on both turrets and a new Super Mill drivetrain producing high horse power and torque for milling speeds up to 6,000 rpm.

The WY-250 includes 25 hp and 20 hp (left and right) spindle motors with Super Mill drivetrain milling motors on the upper and lower turrets, offering 10 hp 40 Nm. To easily accommodate these speeds, the WY-250 weighs 26,460 lb, offering high rigidity. In addition, a 60 deg slant bed offers easy access to the work and tooling. The WY-250 is ideal for a broad range of applications including diversified, small-lot production to mass production. "The WY-250 offers our customers a milling and turning solution with more horse power and torque than competitive machines. When combined with the dual Y axis, very aggressive chip removal rates are obtained along with the ability to perform one-hit machining which reduces operations and cuts cycle times by up to 50 percent," said Mr. Richard Parenteau, Director of Application Development at Methods Machine Tools, Inc.

The WY-250 system includes 24 rotating, milling tool stations. Two 12-station turrets with half-index capability (48 total) is standard. Offering extensive capacity, the WY-250 features a maximum turning diameter of 8.5 in (215 mm) and a turning length of 23 in (580 mm). Bar capacity on the left spindle is 2.6 in (65 mm) and on the right is 2 in (51 mm). Spindle speeds are up to 4,500 min-1 (left) and up to 5,000 min-1 (right). Slide travel on the X1/X2-axis is 6.3 in (160.5 mm)/6.3 in (160 mm), on the Z1/Z2-axis is 23 in (580 mm)/23 in (580 mm) and on the Y-axis upper turret/lower turret is ± 2 in (50 mm)/- 2 in (50 mm), + .8 in (20 mm). For efficient operations, the WY-250 system includes functionality to facilitate multi-tasking programming and set-up, reducing fixture costs of complex parts and production stops. The WY-250 System is offered in a compact footprint with dimensions (w x l x h) of 175 in (4436 mm) x 105 in (2674 mm) x 94 in (2395 mm). Manual Guide i (conversational programming) simulation and optimization software is standard on the WY-250 system for post processing/simulation processes.
