Technical Description

The SAN SHING SE-2840 Manual Lathe is a heavy-duty precision engine lathe designed for demanding turning applications. Featuring a robust, heavily ribbed wide bed constructed from high-strength cast iron, the machine ensures exceptional rigidity and vibration damping for accurate, heavy cutting operations. The lathe offers a 28-inch swing over the bed and a 19.5-inch swing over the cross slide, with a center distance of 40 inches, accommodating large workpieces. The main spindle, supported at three points by high-precision bearings, has a large diameter and a through-bore of 3.125 inches, enabling the machining of long bar stock. Spindle speeds range from 15 to 1,000 RPM, with 12 speed changes for optimal control across various materials and operations. The lathe is powered by a 10 horsepower main motor, providing ample torque for heavy-duty tasks. The spindle nose is compatible with A2-8, A2-11, D1-8, and D1-11 configurations, and the taper of the center is M.T. No.5. The machine delivers longitudinal feeds from 0.05 to 0.7 mm/rev and cross feeds from 0.025 to 0.35 mm/rev, supporting both inch and metric threading standards. The cross slide travel is 425 mm (16.5 inches), and the compound rest travel is 250 mm (10 inches). The tailstock features a quill diameter of 80 mm (3-1/8 inches), quill travel of 230 mm (9 inches), and a taper of M.T. No.5. The SE-2840 is engineered for durability, precision, and versatility in industrial environments.
