NAKAMURA TOME SC-450 CNC LATHES

Technical Description

The Nakamura-Tome SC-450 Horizontal Machining Center is a high-performance turning center designed for precision and heavy-duty machining. It features a powerful main spindle with a maximum turning diameter of 13.78 inches, turning length of 29.24 inches, and a 12-inch chuck diameter, supported by a 40 HP motor capable of 2,500 RPM. The main spindle also accommodates a bar diameter up to 3.19 inches and offers a maximum swing of 31.89 inches. A sub-spindle equipped with a 15 HP motor runs at 3,500 RPM, enabling complex part machining and enhanced productivity. The machine is equipped with a dodecagonal 12-tool turret for turning and rotary tools, with rotary tools powered by a 7.5 HP motor at 3,600 RPM. It supports single simultaneous cutting tool operation across 2 axes standard, with an optional 3-axis capability. Travel distances include 8.76 inches on the X-axis and 25 inches on the Z-axis (optionally 29.33 inches), both offering rapid traverse rates of 786 inches per minute. The Y-axis rapid traverse matches that of X and Z axes at 786 ipm. Its robust design incorporates a 45-degree slant bed for maximum rigidity and box-type slides for precision machining and high accuracy. This machining center is equipped with FANUC CNC control and servo drives to ensure reliable and efficient operation, making it suitable for complex, high-precision parts production.
