SAN SHING SE-28240 MANUAL LATHES

Technical Description

The SAN SHING SE-28240 is a heavy-duty precision engine lathe designed for industrial machining operations. This manual lathe features a 28-inch swing capacity with an extended 240-inch center distance, making it suitable for processing long workpieces. The spindle bore measures 3.125 inches, accommodating various tooling configurations and providing ample clearance for through-spindle operations. Powered by a robust 10-horsepower motor, the machine operates at a maximum spindle speed of 1,000 RPM with 12 selectable speed changes, enabling versatile cutting applications across different material types. The swing over cross slide of 19.5 inches permits working on larger diameter components. The lathe features a heavily ribbed, induction-hardened and precision-ground bed constructed from high-strength FC-25 cast iron, ensuring rigidity and dimensional stability during heavy cutting operations. The machine incorporates precision-ground spindle bearings providing three-point support for superior accuracy and longevity. Longitudinal feeds range from 0.05 to 0.7mm per revolution, while cross feeds vary from 0.025 to 0.35mm per revolution, supporting both metric threading (0.8-14mm) and inch threading (2-28 TPI). The cross slide travel accommodates 425mm of lateral movement, with the compound rest providing 250mm of travel. Designed for heavy-duty production environments, the SE-28240 combines robust construction with precision engineering, making it ideal for general machining, threading, and facing operations on medium to large-scale workpieces in manufacturing facilities.
