CNC machine, short for Computer Numerical Control machine, is a high-precision and high-efficiency automated mechanical processing equipment. Controlled by pre-programmed digital programs, it can automatically process various mechanical parts without manual operation, replacing traditional manual processing tools. It integrates mechanical, electronic, automatic control and computer technologies, supporting cutting, milling, drilling, grinding, turning and other complex processing procedures. It can accurately process all kinds of metal and non-metal workpieces with complex shapes, and is core equipment for modern intelligent manufacturing and mechanical processing industry.
