Technical Description

The SAN SHING SK-2640 is a heavy-duty manual lathe designed for precision machining with a 26-inch swing and 40-inch distance between centers, accommodating large and long workpieces. It features a robust 3.05-inch diameter spindle bore, powered by a 7.5 horsepower motor delivering speeds up to 1,200 RPM. The lathe provides a 13-inch swing over the cross slide, allowing versatile turning capabilities. Its bed is constructed from high-strength FC-25 cast iron with a heavily ribbed structure for rigidity and vibration resistance, essential for heavy cutting operations. The main spindle is precision ground and supported by high-precision bearings at three points, ensuring stability and accuracy during machining. The machine's gearbox incorporates steel alloy gears and splines, hardened and precision ground for durability, enabling quick and easy speed changes via a dial rotary system. Additional features include an adjustable overload safety device in the apron and carriage, and manual or automatic lubrication systems to enhance longevity and maintenance ease. The tailstock is equipped with reduction gearing and graduated quill for precise drilling and boring tasks. An emergency brake pedal provides immediate power cut-off for safe operation. This lathe is ideal for demanding metalworking tasks requiring high precision and heavy cutting capacity.
