SAN SHING SHF-4000 MANUAL LATHE

Technical Description

The SAN SHING SHF-4000 Manual Lathe is a heavy-duty precision engine lathe designed for demanding industrial turning applications. Featuring a robust cast iron FC-25 bed with a high-tensile box-shaped structure, the machine delivers exceptional rigidity and vibration damping for superior accuracy during heavy cutting operations. The lathe offers a swing over bed of 66.93 inches (1700 mm) and a swing over cross slide of 53.94 inches (1370 mm), accommodating large workpieces with ease. The distance between centers is 157.48 inches (4000 mm), providing ample capacity for extended workpieces. The main spindle boasts a generous bore diameter of 6.02 inches (153 mm), allowing for the passage of large-diameter stock or bar feeding. Powered by a 30 horsepower motor, the SHF-4000 delivers reliable torque for heavy-duty machining, with a maximum spindle speed of 170 RPM, optimized for high-force turning tasks. The spindle is precision ground and supported at three points by high-precision bearings, ensuring long-term accuracy and durability. The lathe’s gear box enables all standard thread pitches—including metric, inch, module, and diametral pitches—without requiring gear changes, streamlining threading operations. Additional features include a heavily ribbed, induction-hardened bed with precision-ground ways, a readily adjustable overload safety device, manual and automatic dual lubrication for slide surfaces, and an emergency brake pedal for rapid, safe shutdown. The SHF-4000 is engineered for precision, reliability, and productivity in heavy industrial environments.
