SHANGHAI SIGMA SC-28G CNC LATHE

Technical Description

This CNC turning machine features a swing capacity of 14.17 inches and a maximum machining length of 9.84 inches, optimized for medium-scale turning operations. It is powered by a 5.36 hp motor delivering up to 4,500 RPM, ensuring robust cutting performance and efficiency. The maximum turning diameter is 4.72 inches, suitable for precision component manufacturing. Control is managed via the advanced GSK980TDb CNC system, which supports up to five controllable feed axes, including a C axis, and two analog spindles with high-speed 2 ms interpolation for smooth and precise motion control. The system offers a rapid traverse speed of up to 60 m/min, with a least command unit precision down to 0.0001 mm, enabling high-resolution machining and complex thread cutting capabilities. The CNC controller includes advanced features such as tool length and wear compensation, tool life management, spindle override from 50%-120%, and constant surface speed control for consistent cutting quality. It supports multiple thread cycles, backlash compensation, and customizable acceleration/deceleration settings, making it adaptable to diverse turning and threading tasks. The robust integration of hardware and software advancements in the GSK980TDb control significantly enhances accuracy and productivity, making this lathe suitable for precision metal cutting and prototyping applications requiring high repeatability and tight tolerances.
