description：1. Strong adaptability to processing objects, adapting to the characteristics of single piece production of products such as molds, providing suitable processing methods for mold manufacturing; 2. High machining accuracy and stable machining quality; 3. Capable of multi coordinate linkage and processing complex shaped parts; 4. When changing the processing parts, generally only the CNC program needs to be changed, which can save production preparation time; 5. The machine tool itself has high accuracy and rigidity, and can choose favorable processing quantities, resulting in high productivity (usually 3-5 times that of ordinary machine tools); 6. High degree of automation in machine tools can reduce labor intensity; 7. Beneficial to the modernization of production management. CNC 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. High requirements for the quality of operators and higher technical requirements for maintenance personnel; 9. High reliability.
