SAN SHING SP-40250 MANUAL LATHES

Technical Description

The SAN SHING SP-40250 is a heavy-duty precision lathe engineered for demanding industrial metalworking applications. This machine features a 40-inch swing capacity and an impressive 250-inch center distance, making it suitable for processing large cylindrical workpieces and extended shaft work. The 9-inch spindle bore accommodates substantial workholding chucks and tooling, providing versatility for various machining operations. Powered by a 15-horsepower motor, the lathe delivers robust cutting performance with a maximum spindle speed of 600 RPM, optimized for heavy-duty operations requiring lower speeds and higher torque. The machine offers a swing over cross slide of 31.5 inches, allowing adequate clearance for large diameter workpieces during turning and facing operations. Constructed with a high-strength cast iron bed (FC-25), the SP-40250 features a bed with high tensile structure designed specifically for heavy cutting applications. The precision engineering ensures rigidity and dimensional stability during extended production runs. The machine incorporates multiple spindle speed selections through a 12-speed gearbox system, enabling operators to optimize cutting parameters for different materials and operations. The lathe is equipped with longitudinal and cross feeds ranging from 0.025-0.7mm/rev, facilitating precise depth of cut control. It accommodates both metric and inch threading capabilities, supporting thread pitches from 0.8-14mm and 2-28 threads per inch respectively. The longitudinal rapid traverse reaches 3.7M/min on the Z-axis, enhancing productivity and reducing non-cutting time during part loading and setup operations.
