NAKAMURA TOME WT-150 STATIC SMOOTH DRUM ROLLER

Technical Description

The 2003 Nakamura Tome WT-150 is a high-rigidity, dual-spindle, dual-turret multitasking turning center optimized for complex, precision machining. It features twin spindles with 6-inch chucks and a maximum turning diameter of 7.5 inches (190 mm) and length of up to 20.3 inches (515 mm). Bar capacity is 2 inches (51 mm). Axis travels include Y-axis ±1.375 inches, X2-axis 6.59 inches, Z2-axis 18.3 inches, B-axis 21.65 inches, with ±0.001° resolution on C1/C2 rotary axes, supporting precise 4-axis machining. The spindle speed reaches 5000 rpm, supported by powerful motors delivering 20 HP on the left spindle and 15 HP on the right spindle. Driven-tool motors for heavy cutting are rated at 7.5 and 5 HP. The machine employs upper and lower 24-station turrets with rotary tools running at 6000 rpm, enabling simultaneous multi-tool operations and cycle time optimization. The distance between spindle noses can be adjusted from 7.9 to 31.5 inches (200 to 800 mm), allowing versatile part lengths. It includes advanced features like individual tool rotation, fine C-axis incremental control, and robust slide travels (Y ±1.4 in, B 23.7 in, X1/X2 6.6 in, Z1/Z2 20.3 in) for precise machining and high throughput. The WT-150 is suited for machining in medical, aerospace, and electronics sectors where tight tolerances and multi-axis capabilities are required. The machine lacks a tailstock and 3-channel simultaneous tooling but excels in multi-turret multitasking for shaft and flange parts up to moderate size and complexity.
