HANKOOK PROTEC-9NB/7000 CNC LATHE

Technical Description

The SZGH-CNC990TDb-2 is an economical, professional 2-axis CNC lathe controller designed for precision turning operations on standard and custom workpieces. This machine operates on two linear axes—the X-axis controlling diameter by moving the tool inward and outward, and the Z-axis controlling length by moving the tool along the workpiece. The lathe features a robust 34.8 hp spindle drive with maximum spindle speed of 800 RPM, enabling efficient material removal across various applications. With a generous 37.4-inch swing over bed and 275-inch machining length, the machine accommodates large-diameter and long components typical in medium to heavy production environments. The integrated tailstock provides essential support for extended workpieces, enhancing rigidity and surface finish quality. Control is managed by the FANUC 32I-A CNC system paired with an 8.4-inch LCD display featuring 800x600 resolution and touch-screen interface for intuitive operator interaction. The system supports automatic tool compensation, tool radius adjustment, and spindle servo speed control for precise dimensional accuracy. Feeding speeds range from 0.001 to 10 m/min with maximum cutting speed of 20 m/min. The controller incorporates ARM, DSP, and FPGA technology with hardware interpolation for smooth linear, circular, and spiral toolpath execution. Minimum input resolution reaches 0.001mm, supporting program sizes up to ±99999.999. Connectivity includes RS232 and USB flash drive interfaces for program transfer and file management. Applications span mini-type special lathes, hardware processing, and automatic equipment manufacturing.
