Introduction to the numerical control system model of 3TD spinning machine:

The 3TD spinning machine CNC system is a specialized CNC system independently developed by Foshan Micro Control Industrial Automation Technology Co., Ltd., specifically designed for spinning machines. This system uses a 32-bit high-performance CPU

The real-time control and hardware interpolation technology, along with the ultra large scale programmable device FPGA, ensure high efficiency at μ m level precision in the system. The editable PLC

Make the logic control function more flexible and powerful. The 3TD system can control 5 feed axes, 2 analog spindles, 1ms high-speed interpolation, 0.1 μ m

Controlling accuracy significantly improves the efficiency, precision, and surface quality of part processing. We have redesigned the software based on the special process of spinning machine processing, making it more convenient and efficient for CNC lathe manufacturers to program, and making the transition of arcs smoother.

Special advantages of the 3TD spinning machine CNC system:
