CNC stands for Computer Numerical Control, which means Computer Numerical Control in Chinese. It is a technology that uses digital instructions to control machine tools, tools, and workpieces for machining. It is often used in manufacturing processes such as turning, milling, and grinding, and can also be applied in fields such as carving, cutting, and engraving. CNC technology can improve production efficiency and machining accuracy, and can also produce high-precision and complex parts.

CNC usually refers to CNC Machine Tools, including CNC lathes, CNC Milling Machines, and machining centers, which can be controlled by programming CNC Machining programs to process machine tools, cutting tools, and workpieces. There are two types of programming: manual programming and automatic programming, which input the programmed program into the CNC system for processing.

Due to the use of computer control, CNC machine tools have the following advantages: 1. Strong adaptability. Significantly reduce the number of tooling, eliminating the need for complex tooling for processing parts with complex shapes. If you want to change the shape and size of a part, you only need to modify the part processing program, which is suitable for new product development and modification.

2. Stable processing quality, high processing accuracy, and high production efficiency.

3. Capable of processing complex parts. It can achieve arbitrary trajectory motion and spatial surface processing of any shape, such as propellers, turbine blades, etc.

4. It can reduce labor intensity and improve working conditions.
