SANHUANJIAN G-250P CNC LATHE

This CNC turning machine features a **16.5-inch swing** and a **machining length of 19.7 inches**, supporting workpieces within these dimensions. It operates at a **maximum spindle speed of 4,500 RPM**, providing high-speed rotation suitable for precision lathe machining. The system is controlled by the **GSK980TD CNC controller**, a 32-bit high-performance controller equipped with a large-scale programmable FPGA, designed for efficient and precise turning operations. The GSK980TD controller supports three-axis linkage and four-axis PLC control, with selectable minimum command units of 0.001mm or 0.0001mm, enabling fine positional accuracy up to 1μm or 0.1μm. It offers fast interpolation cycles of 2ms and advanced spindle functions including continuous position control, rigid tapping, spindle override (50%–120%), and constant surface speed control (G96/G97). The controller facilitates complex feeding operations, acceleration and deceleration functions with configurable linear or S-type curves, and comprehensive tool functions such as tool length compensation, nose radius, and wear compensation. The system supports multiple thread pitches ranging from 0.01mm to 500mm or equivalent in threads per inch. It integrates a robust PLC programming environment using ladder logic for automation and machine control tasks. I/O points are extendable, and connectivity options include RS232, USB, and network interfaces. This turning machine is suited for high-precision metal machining processes requiring reliable and adaptable CNC control.
