Introduction:

NC660Tb is a high-performance lathe CNC system independently developed by PORCHESON. It adopts an integrated drive control architecture, integrating CNC control system, servo drive system, IO module, etc. The control accuracy and dynamic performance have been greatly improved to meet the needs of high-speed and high-precision machining; The CNC panel adopts an 8-inch LCD display, and the human-machine interface adopts configuration software to achieve a more friendly and beautiful appearance. The open PLC ladder design interface is simple and easy to use.
