SHANGHAI SIGMA SC6136 (A) 500 CNC LATHE

Technical Description

This is a precision CNC turning lathe equipped with a GSK980TD control system, designed for sophisticated machining operations. The machine features a 14.17-inch swing capacity and 17.72-inch machining length, accommodating workpieces up to 7.09 inches in turning diameter. The 8-inch chuck provides secure workpiece holding, while the included tailstock enables extended workpiece support for enhanced machining accuracy and stability. Powered by a 5.36 horsepower motor, the lathe delivers a maximum spindle speed of 2,500 RPM, suitable for both roughing and finishing operations across various materials. The 2-axis configuration enables controlled movement in the X and Z planes, allowing for complex turning profiles and precision cylindrical work. The GSK980TD CNC controller represents advanced automation technology, featuring 69 G-commands including rapid positioning, linear and circular interpolation, thread cutting, and rigid tapping capabilities. The system provides rapid speeds from 0-100,000 mm/min with four levels of real-time adjustment, while cutting feed speeds reach up to 15,000 mm/min with sixteen adjustment levels. Thread cutting functionality supports both metric (0.01mm-1000mm pitch) and imperial specifications with customizable acceleration profiles. The controller delivers 1nm position accuracy through its bus-type servo drive unit and multi-turn 23-bit absolute encoder servo motor, ensuring repeatable precision. With embedded PLC functionality and macro program capabilities, this machine tool combines robust mechanical construction with sophisticated digital control for professional production environments.
