NAKAMURA-TOME WT-250II HORIZONTAL MACHINING CENTER

Technical Description

The Nakamura-Tome WT-250II is a high-performance horizontal machining center featuring dual spindles and dual turrets designed for efficient multitasking in precision turning and milling operations. It supports a maximum turning diameter of 9.84 inches (250 mm) and a maximum turning length of 21.85 inches (555 mm), accommodating bar diameters up to 2.0 inches (51 mm) standard, with optional 2.5 inches (65 mm) capacity on the left spindle. Each spindle delivers up to 25 HP with speeds reaching 4,500 RPM, and includes precise indexing increments of 0.030 degrees. The machine's twin turrets each hold up to 24 turning tools and 12 rotary tools, enabling up to two simultaneous cutting tools for increased productivity. The WT-250II features 8-axis control with X, Y, and Z axis travel of 7.677 inches, 3.230 inches, and 23.620 inches respectively, all capable of rapid traverses up to 629 inches per minute. The turrets support milling and drilling with Y and C axis functionality standard, driven by rotary tools rated at 7.5 HP and speeds up to 6,000 RPM, enabling complex contouring and off-center milling. Constructed with high-rigidity slide ways and servo-driven dodecagonal turrets, the machine offers stable, high-precision machining for diversified production, balancing cycle times via its opposing spindles and flexible tool configurations. The WT-250II suits variable lot sizes requiring multitasking, including shaft turning and milling, with advanced features such as simultaneous balance cutting and heavy cutting capability with small tools on the driven turret stations. Overall, it is engineered for efficiency, versatility, and high accuracy in demanding manufacturing environments.
