The KY980TB/KY980Tc lathe CNC system is a dual/three-axis CNC system based on the KY000T lathe CNC system for software and hardware re-optimization. The system adopts 32-bit high-performance CPU and ultra-large-scale programmable device FPGA. Real-time control and hardware interpolation technology ensure the high efficiency of the system with μm-level precision. The editable PLC makes the logic control function more flexible and powerful. The KY980TB system can control 3 feed axes, 1 analog spindle, 1ms high-speed interpolation, and 0.1μm control accuracy, which significantly improves the efficiency, accuracy and surface quality of parts processing.
