SAN SHING SHA-7000 MANUAL LATHES

Technical Description

The SAN SHING SHA-7000 is a heavy-duty precision manual lathe engineered for demanding industrial applications requiring sustained cutting performance and dimensional accuracy. Built with a high-strength cast iron FC-25 bed featuring a box-shaped lower section with integrated chip pan, the machine delivers exceptional rigidity and thermal stability during extended operations. The lathe accommodates workpieces up to 36.22 inches in swing diameter, with a generous 275.59-inch center distance enabling the machining of lengthy cylindrical components. Its 6.02-inch spindle bore supports large-diameter tooling and workholding accessories, while the precision-ground spindle is supported at three points by high-precision bearings for concentricity and runout control. The cross-slide provides 25.59 inches of over-swing clearance, facilitating radial tool positioning for profiling, facing, and boring operations. Operating at 320 RPM with 15.0 horsepower, the machine generates substantial cutting torque suitable for heavy roughing passes and interrupted cuts in ferrous and non-ferrous materials. The gear box accommodates metric and inch thread pitches without gear changes, supporting manual thread generation across standard module and diametral pitch specifications. Manual and automatic dual lubrication systems maintain optimal slide surface conditions, while an overload safety device protects against inadvertent tool breakage. An emergency brake pedal enables immediate power cutoff and rapid machine stoppage, ensuring operator safety and precision control during critical operations.
