SANHUANJIAN G-120 CNC LATHE

Technical Description

This CNC lathe system features a **17.32-inch swing** and a **machining length of 19.68 inches**, suitable for medium-sized turning operations. It supports a **maximum spindle speed of 4,500 RPM** and allows a **maximum turning diameter of 6.29 inches**, providing versatility for diverse workpiece dimensions. The machine is controlled by the **GSK980TD CNC controller**, a high-performance system equipped with a 32-bit CPU and a multi-turn 23-bit absolute encoder servo motor ensuring 1nm position accuracy. The controller supports up to **5 axes**, including linear and circular interpolation, enabling precise multi-axis machining. It offers extensive programming capabilities including absolute/incremental programming, diameter/radius programming, and metric/inch unit conversion. The controller incorporates advanced feed functions with rapid speed adjustments from 0 to 100,000 mm/min and cutting feed speed up to 15,000 mm/min, and supports 16 levels of real-time feed magnification adjustment. Its spindle control covers speeds from 0 to 9,999 RPM with 50% to 120% spindle override, all adjustable in real time. The integrated PLC supports ladder programming with 5 control axes, enabling automation of complex tasks. Tool compensation functions, thread cutting with variable pitch, multiple thread types, and rapid positioning G functions enhance productivity and precision. The system also includes advanced features like spindle speed analog voltage control, constant surface speed control (G96/G97), and support for macro program calling. It is designed for robust, high-precision CNC turning applications with enhanced automation and programming flexibility.
