SAN SHING SP-4070 MANUAL LATHES

Technical Description

The SAN SHING SP-4070 is a heavy-duty precision manual lathe designed for large-scale machining operations and industrial production environments. This machine features an impressive 40-inch swing capacity, enabling operators to work with substantial workpieces up to that diameter. The 70-inch center distance accommodates extended workpieces, making it ideal for shaft production, large cylindrical components, and precision turning applications. The lathe is equipped with a substantial 9-inch spindle bore, facilitating the mounting of various workholding devices and accessories. The 31.5-inch swing over cross slide provides additional clearance for complex part geometries and secondary operations. Powered by a 15-horsepower motor, the SP-4070 delivers sufficient cutting force for heavy-duty roughing and finishing operations. Operating at a maximum of 600 RPM, this lathe prioritizes cutting power and stability over speed, making it well-suited for large-diameter work and deep cuts in demanding materials. The manual operation allows skilled machinists direct control over cutting parameters and workpiece positioning, facilitating precision and adaptability. Constructed from high-strength cast iron FC-25 with a box-shaped bed design, the SP-4070 provides exceptional rigidity and vibration dampening essential for maintaining dimensional accuracy during heavy cutting. The robust construction, combined with comprehensive feed systems and multiple spindle speed options, positions this lathe as a reliable workhorse for tool rooms, manufacturing facilities, and specialized machining operations requiring precision and durability in large-scale component production.
