SHARP 30120B MANUAL LATHE

Technical Description

The SHARP 30120B is a heavy-duty precision engine lathe engineered for large-scale metal turning operations. Featuring a 30-inch swing over bed and 120-inch distance between centers, this machine accommodates substantial workpieces with exceptional capacity. The lathe incorporates a 4.5-inch spindle bore with a D1-11 Camlock spindle nose, providing secure and rapid tool changes. Powered by a robust 15 horsepower motor operating at 230V, 3-phase, the machine delivers 12 selectable spindle speeds ranging from 10 to 1,000 RPM, enabling both heavy-duty cutting at low speeds for maximum torque and precision finishing at higher speeds. The 21-inch swing over cross slide facilitates versatile workholding configurations, while the one-piece cast meehanite bed ensures structural rigidity and dimensional stability during extended operations. Standard features include a quick-change gearbox for efficient thread selection, direct switching between inch and metric threading modes, and optional dual chuck availability for enhanced versatility. The 16-inch-wide bed provides ample support for long stock machining. Weighing 8,316 pounds and measuring 15.58 by 3.75 by 6.41 feet, this floor-mounted machine represents a substantial investment in production capacity. The geared head design, combined with low-speed torque capabilities down to 10 RPM, makes the 30120B ideal for demanding applications including heavy-duty facing, boring, threading, and precision turning of large diameter components in manufacturing, job shop, and contract machining environments.
