SANHUANJIAN G-CNC6195/4000 CNC LATHE

Technical Description

This CNC lathe features a **37.4-inch swing** and a **machining length of 157.48 inches**, powered by a **14.75 hp motor** capable of reaching a **maximum spindle speed of 800 RPM**. The control system is the **GSK980TD CNC controller**, a high-performance unit with a 32-bit CPU and FPGA-based hardware interpolation, achieving **micrometer-level positioning precision**. The controller supports up to **5 linkage axes** with linear interpolation and **2 axes circular interpolation**, enabling complex multi-axis machining. Its spindle control includes real-time speed override from 50% to 120%, rigid tapping, and spindle orientation, with a speed range extendable up to 9999 RPM via the control system’s parameters. Feed rates can be rapidly adjusted from 0 mm/min up to 100,000 mm/min in rapid traverse and 15,000 mm/min for cutting feed, with acceleration and deceleration customizable via S-curve or linear profiles. The system holds extensive programmability, supporting diameter/radius programming, inch/metric conversion, compensation functions (tool length, tool nose radius, pitch error), and memory capacity for thousands of part programs. A comprehensive built-in PLC controls multiple feed axes and automatic tool functions, allowing flexible operation and automation. The controller supports bidirectional CNC-PC communication, program editing with full-screen interface, multi-language display options, and fault diagnostics. These features combine for high-precision, efficient turning operations with CNC automation tailored for complex, large swing machining tasks.
