SAN SHING SK-2680 MANUAL LATHE

Technical Description

The SAN SHING SK-2680 is a heavy-duty manual engine lathe designed for precision turning tasks. It features a 26-inch swing over the bed and 13-inch swing over the cross slide, with a center-to-center distance of 79.9 inches, allowing machining of long workpieces. The spindle bore diameter is 3.05 inches, accommodating larger stock. Powered by a 7.5 HP motor, the lathe achieves speeds up to 1,200 RPM, providing a versatile range for various cutting operations. The machine's robust construction includes a heavily ribbed, induction-hardened, and precision-ground bed for stability and accuracy. Its spindle is precision-ground and supported at three points by high-precision bearings, enhancing rigidity and smooth operation during heavy cutting. The headstock incorporates gears and splines made from hardened steel alloys with a dial rotary system for quick speed changes. The lathe includes manual and automatic dual lubrication for slide surfaces, an overload safety device on the apron and carriage, and an emergency brake pedal for immediate machine stoppage to ensure operator safety. The tailstock features a quill with metric and inch graduations and reduction gearing to aid drilling operations. This model is built to handle both inch and metric threads with various pitches without changing gears, facilitating threading flexibility. The overall design is optimized for heavy-duty, precise, and reliable machining in manufacturing environments where long parts and strong spindle capacity are required. The machine weighs approximately 5,621 lbs and offers a swing over gap of up to 37 inches for handling larger diameter workpieces.
