SAN SHING SE-3640 MANUAL LATHE

Technical Description

The SAN SHING SE-3640 manual lathe is a heavy-duty precision lathe designed for robust machining tasks. It features a large swing capacity of 36 inches and centers of 40 inches, allowing it to handle sizable workpieces. The spindle bore measures 3.125 inches, accommodating substantial tooling and material sizes. Driven by a 10-horsepower motor, it provides strong cutting power and a maximum spindle speed of 1,000 RPM. The lathe offers a swing over the cross slide of 27.5 inches, enabling versatility in turning operations. The machine includes a heavily ribbed wide bed with induction-hardened and precision-ground ways, ensuring stability and accuracy during heavy cutting. The main spindle is precision ground, supported at three points by high-precision bearings for enhanced rigidity and smooth operation. The gear box allows cutting of all standard thread pitches—including metric, inch, module, and diametral pitches—without gear changes, aided by a dial rotary system for quick speed adjustments. The lathe’s cross slide travel is approximately 16.5 inches, with a compound rest travel of 10 inches, providing flexibility for detailed machining. The quill has a 3-1/8 inch diameter and 9 inches of travel with a taper of M.T. No. 5, making it suitable for drilling and boring operations. This model is engineered for precision and heavy-duty use, ideal for demanding industrial environments requiring reliability and durable performance. It is well-suited for machining large components with high precision.
