NAKAMURA-TOME WY-250 HORIZONTAL MACHINING CENTER

Technical Description

The Nakamura-Tome WY-250 is a sophisticated 9-axis CNC horizontal machining center featuring dual opposed spindles with independent 4,500 RPM capability and 25 HP motors each. This multitasking machine accommodates workpieces up to 8.46 inches in diameter and 22.84 inches in length, with maximum bar capacity of 2.55 inches. The machine utilizes an innovative twin-turret configuration with 48 total tool stations—24 on both the upper and lower turrets—enabling simultaneous cutting operations with up to two tools. Each turret features independent Y-axis travel of ±1.97 inches and integrated milling/drilling capabilities with 6,000 RPM rotary drives rated at 10 HP. The WY-250 delivers comprehensive 9-axis control across X, Y, Z, and B2 axes with rapid traverse rates reaching 707 ipm, combined with programmable cutting feeds from 1–315 ipm. Standard functionality includes on-center and off-center secondary milling with full C-axis rotation capability, while the opposing spindle arrangement minimizes workpiece imbalance during simultaneous operations. This configuration optimizes cycle times for complex components requiring multi-sided machining without part repositioning. The machine features full box-way slide construction with a 60-degree slant bed design, providing exceptional rigidity and repeatability. Weighing 12,000–13,000 kg and occupying approximately 4,620 mm × 2,593 mm of floor space, the WY-250 represents an efficient solution for high-volume precision turning and milling operations.
