SAN SHING SF-3270 MANUAL LATHE

Technical Description

The SAN SHING SF-3270 manual lathe is a heavy-duty precision machine designed for versatile metalworking applications. It features a robust swing capacity of 32.0 inches and a generous distance between centers of 70.2 inches, accommodating large workpieces. The spindle bore is 4.0 inches, allowing passage of substantial material, while the spindle speed reaches up to 1,000 RPM, providing an optimal balance between power and precision. The machine is powered by a 15.0 HP motor, delivering substantial torque for heavy cutting tasks. The swing over the cross slide measures 23.5 inches, enabling effective machining of larger diameters on the carriage. Constructed with a high-strength cast iron bed (FC-25), the lathe offers excellent rigidity and vibration damping, essential for precise and stable operations under heavy loads. It incorporates 12 spindle speed changes, longitudinal feed rates from 0.05 to 0.7 mm/rev, and cross feed rates from 0.025 to 0.35 mm/rev, allowing fine control during threading and cutting. The apron and carriage feature an adjustable overload safety device and dual lubrication systems (manual and automatic) to maintain smooth sliding surfaces and extend durability. The tailstock is designed with high tensile strength and includes reduction gearing for drilling operations. Overall, the SF-3270 combines substantial machining capacity with precision features suited for demanding industrial applications requiring both power and accuracy.
