J & W SK 6136H / 750 CNC LATHE

Technical Description

This CNC lathe system features a **swing capacity of 14.57 inches** and a **machining length of 29.53 inches**, making it suitable for medium-sized turning operations. It is controlled by a **GSK CNC system**, specifically the GSK980TDa version, which supports multi-axis control including X, Z, and Y axes with linkage interpolation and high-precision control increments of 0.001 mm. The control employs advanced functions such as **pitch error compensation, backlash compensation, tool length, tool wear, and tool nose radius compensation** for improved machining accuracy. It includes an **embedded PLC** for ladder programming and automation, along with powerful macro command programming capabilities for complex and customizable machining cycles. The CNC system features **exponential acceleration/deceleration to support high-speed, high-precision machining**, and supports a variety of threading cycles including metric, inch, taper, variable pitch, and high-speed thread cutting with retraction control. The interface supports multiple languages (Chinese, English, Spanish) and provides a large memory (6144KB) capable of storing up to 384 programs with full-screen editing. Communication is bidirectional between CNC and PC, with password-protected multi-level management for operational security. The system also offers key features such as spindle speed floating to reduce chatter, tool breakage detection, chip breaking technology, and enhanced rough turning cycle optimization to increase machining efficiency on shaft parts. Overall, this CNC lathe is ideal for precision turning with flexible control, robust compensation, and efficient programming and operation functions.
