CNC (Computer Numerical Control) machining is a technology that uses computer-controlled machine tools for precision machining. The basic principle is to use computer programming to control the movement of the machine tool, thereby achieving precise machining of workpieces. The core of CNC machining is the CNC system, which consists of a computer, controller, servo drive system, and machine tool. The CNC system reads pre-written machining programs and controls the precise movement of each axis of the machine tool to complete complex machining tasks.

The CNC machining process typically includes the following steps: first, design a CAD model based on machining requirements; then, use CAM software to convert the CAD model into a CNC program; next, input the CNC program into the CNC machine tool; finally, start the machine tool for machining. Throughout the process, operators need to closely monitor the machining status to ensure quality and safety.

The advantages of CNC machining lie in its high precision, efficiency, and flexibility. It can machine workpieces with various complex shapes and can repeatedly perform high-precision machining. Additionally, CNC machining can reduce human errors, improve production efficiency, and enhance product quality.
