Technical Description

The SAN SHING SK-2280 Manual Lathe is a heavy-duty precision lathe designed for robust machining tasks. It features a swing capacity of 21.97 inches (approximately 559 mm) and a distance between centers of 79.84 inches (around 2,030 mm), allowing the handling of large workpieces. The lathe is powered by a 7.5 HP motor, delivering up to 1,200 RPM spindle speed. Its spindle bore measures 3.05 inches (about 77.5 mm), suitable for through-spindle operations with high rigidity. The swing over cross slide is 13.00 inches, providing versatile machining capability with a wide cross slide travel. The machine bed is constructed of high-strength cast iron (FC-25) with a heavily ribbed, wide design featuring induction-hardened and precision-ground ways for enhanced rigidity and precision during heavy cutting. The main spindle is large diameter, precision ground, and supported at three points by high-precision bearings for stability. The lathe incorporates a dial rotary system for easy and quick speed changes, adjustable overload safety devices on the apron and carriage, and manual/automatic dual lubrication to ensure smooth operation and durability. Additional features include an emergency brake for rapid power cutoff and tailstock with reduction gearing and graduated quill for precise drilling. This model supports a full range of standard thread pitches without requiring gear changes, suitable for metric, inch, module, and diametral pitches. Overall, the SAN SHING SK-2280 provides high capacity, precision, and reliability for heavy-duty manual turning applications.
