Introduction to the Definition of Numerical Control Machine Tools

Numerical control machine tool refers to an automated machining equipment that controls the motion, spindle, tool, worktable, and auxiliary devices of the machine tool through a computer digital control system. It is mainly used for precision manufacturing processes such as turning, milling, drilling, boring, grinding, gear machining, and electrical discharge machining of metals and other engineering materials. CNC stands for Computer Numerical Control. Numerical control machine tools are usually composed of the machine body, numerical control system, servo drive system, spindle system, tool magazine, cutting tools, fixtures, lubrication and cooling system, chip removal system, safety protection device, etc. Common products include machining centers, CNC lathes, gantry and boring milling machines, gear machining machines, CNC grinders, EDM machines, and multi axis linkage machining equipment. Compared with traditional machine tools, CNC machine tools have higher machining accuracy, repeat positioning accuracy, production efficiency, and the ability to process complex parts, making them one of the basic equipment in modern manufacturing. In practical applications, CAD/CAM software usually converts product design into machining programs such as G-code, and then the CNC system executes machining paths and motion control.
