SHANGHAI SIGMA SC-20G CNC LATHE

Technical Description

This CNC lathe system features an 11.81-inch swing and a machining length of 3.94 inches, capable of handling turning diameters up to 5.12 inches. It is powered by a 5 hp motor delivering a maximum spindle speed of 6,000 RPM, suitable for medium-duty precision machining. The control system is the GSK980TDb CNC, which supports up to five controllable feed axes, including X, Z, and Y axes plus additional optional ones, and two analog spindle controls. The system facilitates high-speed interpolation with a 2ms cycle time and achieves rapid traverse speeds up to 60 m/min. It offers various threading functions including single, multi-metric, taper, end-face, constant pitch, and variable pitch threads with fine pitch increments ranging from 0.01 mm up to 500 mm. Advanced features include spindle override (50% to 120%), constant surface speed control, rigid tapping, and comprehensive tool management functions such as tool length and wear compensation, tool life management, and multiple tool-setting modes. Precision compensation mechanisms include backlash and memory pitch error corrections to enhance machining accuracy. The interface uses a high-resolution LCD display for real-time monitoring and control, with programmable acceleration and deceleration profiles for optimized cutting performance. This system is designed for flexibility, accuracy, and efficient CNC turning operations in industrial applications requiring moderate part sizes and complex threading capabilities.
