NAKAMURA-TOME SC-300 HORIZONTAL MACHINING CENTER

Technical Description

The Nakamura-Tome SC-300 is a robust CNC horizontal turning center designed for precision shaft and component machining. This machine features a single 10-inch chuck with a maximum turning diameter of 13.78 inches and can accommodate bar stock up to 2.8 inches in diameter, with a maximum turning length of 23.62 inches. The main spindle delivers 30 horsepower at speeds up to 3,500 RPM, providing powerful cutting capability for demanding production applications. The machine is equipped with a 12-station turret capable of holding both turning and rotary cutting tools, supplemented by a 7.5 HP rotary milling spindle running at 3,600 RPM, enabling multi-axis machining versatility. The X-axis provides 8.76 inches of travel with rapid traverse rates of 786 inches per minute, while the Z-axis offers 25 inches of travel at comparable rapid speeds. The rigid box-way slide design ensures high accuracy and repeatability across all axes, with the machine weighing approximately 10,230 pounds. A 45-degree slant bed design maximizes rigidity and improves chip evacuation. The SC-300 is controlled by FANUC CNC systems with servo drives, making it highly reliable and programmable for complex multi-task operations. The inclusion of live tooling capability with Y-axis travel enhances the machine's flexibility for contoured parts and detailed finishing work.
