SAN SHING SF-28170 MANUAL LATHES

Technical Description

The SAN SHING SF-28170 manual lathe is a heavy-duty precision machine designed for large-scale machining operations. It features a robust 28.0-inch swing over the bed and a long center distance of approximately 169.9 inches, allowing it to accommodate very long workpieces. The spindle bore diameter is 4.0 inches, supporting the passage of sizable bars through the spindle for complex machining tasks. Powered by a 15.0 HP motor, the lathe achieves spindle speeds up to 1,000 RPM, providing sufficient power and speed for demanding cutting operations. The swing over the cross slide is 19.5 inches, enabling effective machining of larger diameters on the cross slide. The lathe bed is constructed from high-strength cast iron (FC-25) with a heavily ribbed wide design, induction-hardened and precision-ground ways, which ensures enhanced rigidity, precision, and longevity under heavy cutting conditions. The design includes a one-piece bed structure that helps in quick clean-up of iron filings and sustains high tensile forces during machining. The main spindle is a large-diameter forging sustained by precision bearings for durability and accuracy. Feed rates and threading capabilities allow fine control for precision work, with various feeds available. Overall, the SF-28170 is engineered for heavy-duty applications requiring high precision, rigidity, and capacity for large and long workpieces in industrial settings.
