CNC machining is a technology that uses computer-controlled digital information to control the movement and machining process of machine tools, replacing traditional manual operation. Its core equipment, the CNC machine tool, consists of a numerical control unit, a programmable logic controller (PLC), a spindle drive, and a feed mechanism, integrating mechanical, electrical, hydraulic, pneumatic, and optical technologies.

This technology achieves automated precision machining of materials such as metals by programming and pre-setting parameters such as tool paths, spindle speeds, and feed rates. A typical application is machining centers equipped with automatic tool changers, which can complete multiple processes such as drilling and milling in a single setup, significantly improving efficiency and accuracy. Modern CNC machine tools are developing towards higher speeds, higher precision, and greater intelligence, supporting the manufacturing of complex parts and widely used in machinery, mold making, aerospace, and other fields, forming one of the core foundations of advanced manufacturing technology.
