SAN SHING SP-3250 MANUAL LATHES

Technical Description

The SAN SHING SP-3250 Manual Lathe is a heavy-duty engine lathe designed for precision turning and robust machining applications. Featuring a 32-inch swing over bed and 50-inch center distance, this lathe accommodates large workpieces with ease. The spindle bore measures 4 inches, allowing for the passage of substantial stock, while the 15 HP motor delivers ample power for demanding cutting operations. The spindle speed ranges up to 1,000 RPM, providing flexibility for a wide range of materials and machining requirements. Swing over the cross slide is 23.5 inches, ensuring sufficient clearance for tooling and workpiece manipulation. The lathe is constructed with a high-strength cast iron bed, offering excellent rigidity and vibration damping for consistent accuracy and surface finish. All critical components are precision-ground and assembled to tight tolerances, ensuring long-term reliability and performance. The headstock spindle is made from special alloy steel, accurately ground and polished for optimal bearing surfaces and durability. The machine features a quick-change gearbox for efficient speed selection, with smooth power transmission through a countershaft design. Automatic lubrication of gears, shafts, and bearings via a plunger pump ensures minimal maintenance and extended service life. The SP-3250 is equipped with a robust carriage and cross slide assembly, enabling precise longitudinal and cross feed movements. This lathe is ideal for heavy cutting, turning, facing, threading, and other general-purpose machining tasks in industrial environments.
