In the manufacturing industry, CNC is mainly used to process and manufacture parts, such as mobile phone cases, auto parts, mold parts, etc. CNC has the characteristics of high precision of processed products, high degree of automation, high production efficiency and low production cost.

Compared with ordinary machine tools, CNC machine tools have the following characteristics:
1. High processing precision and stable processing quality.
2. Multi-coordinate linkage can be carried out, and parts with complex shapes can be processed.
3. When machining parts change, generally only need to change the NC program, which can save production preparation time.
4. The machine tool itself has high precision and high rigidity, can choose a favorable processing amount, and has high productivity (generally 3~5 times of ordinary machine tools).
5. The machine tool has a high degree of automation, which can reduce labor intensity.
6. Mass production, product quality is easy to control.
7. The quality requirements for operators are low, and the technical requirements for maintenance personnel are relatively high.
