The operation and monitoring of CNC machine tools are all completed in this CNC unit, which is the brain of CNC machine tools. Compared with ordinary machine tools, CNC machine tools have the following characteristics:

1. Strong adaptability to processing objects, suitable for the characteristics of single-piece production of molds and other products, providing a suitable processing method for mold manufacturing; processing parts on CNC machine tools mainly depends on the processing program, which is different from ordinary machine tools. There is no need to manufacture, many molds and fixtures need to be replaced, and the machine does not need to be readjusted frequently. Therefore, the CNC machine tool is suitable for the occasions where the processed parts are frequently changed, that is, suitable for the production of single pieces, small batch products and new product development, thereby shortening the production preparation cycle and saving a lot of process equipment costs.

2. High processing accuracy and stable processing quality. The processing accuracy of CNC machine tools can generally reach 0.05-0.1MM. CNC machine tools are controlled in the form of digital signals. Each time a pulse signal is output by the CNC device, the moving parts of the machine tool move one. The pulse equivalent (generally 0.001MM), and the average backlash of the machine tool feed chain and the average error of the screw pitch can be compensated by the numerical control device. Therefore, the positioning accuracy of the numerical control machine tool is relatively high.

3. Multi-coordinate linkage can be performed to process parts with complex shapes; the same batch of parts are processed on the same machine under the same processing conditions, using the same tool and processing program, the tool trajectory is exactly the same, and the consistency of the parts Good, stable quality.

4. When the processing parts are changed, generally only the NC program needs to be changed, which can save production preparation time;

5. The machine tool itself has high precision and rigidity. It can choose favorable processing volume and high productivity (generally 3 ~ 5 times of ordinary machine tools). CNC machine tools can effectively reduce the processing time and auxiliary time of parts. The range of sonic five-axis linkage machining centers and feeds is large, allowing the machine to perform powerful cutting with large cutting volumes. CNC machine tools are entering the era of high-speed machining. The rapid movement and positioning of mobile parts and high-speed cutting of CNC machine tools have greatly improved productivity. In addition, it can be used in conjunction with the tool magazine of a machining center to achieve continuous processing of multiple processes on one machine tool, reducing the turn-around time between processes of semi-finished products and improving productivity.

6. The machine tool has a high degree of automation, which can reduce labor intensity. After the CNC machine tool is adjusted before processing, enter the program and start, and the machine tool can automatically and continuously process until the end of processing. The operator only needs to input, edit, edit, load and unload parts, prepare tools, observe machining status, and inspect parts. The labor intensity is greatly reduced, and the labor of machine tool operators tends to be intelligent. In addition, machine tools are generally integrated, both clean and safe.

7. Conducive to the modernization of production management. Numerically controlled machine tools use digital information and standard codes to process and transmit information, and use computer control methods, laying the foundation for the integration of computer-aided design, manufacturing and management

8. The quality requirements of operators are high, and the technical requirements of maintenance personnel are higher;

9. High reliability.
