1999 Nakamura Tome SC-450 CNC Lathe

The 1999 Nakamura Tome SC-450 CNC Lathe is a powerhouse turning center designed for large-diameter, high-torque machining applications. Engineered with heavy-duty construction and renowned Japanese precision, this model is equipped with a 12-station dodecagonal turret and offers optional driven tools and a milling spindle—making it an attractive choice for shops requiring multitasking capabilities. With a maximum turning diameter of 18.3 inches and a maximum turning length of 30.9 inches, it provides ample working envelope for large components. The spindle bore is 3.94 inches, complemented by a 40 HP spindle motor capable of delivering consistent cutting torque even at the maximum speed of 2,500 RPM.

Travel distances are generous, with 12.4 inches on the X-axis and 32.5 inches on the Z-axis, while rapid traverses of 472 IPM (X) and 708 IPM (Z) ensure reduced idle times. The tailstock, with a 4.72-inch quill diameter and 3.94-inch stroke, is designed for serious support during long-part turning operations. The optional live tooling adds up to 3,600 RPM of milling capability, driven by a dedicated 7.3 HP motor, enabling simultaneous turning and milling. The machine weighs approximately 12,800 lbs, reflecting its stable and rigid structure—critical for heavy-duty cuts.
