A CNC machine tool is a machine tool controlled by a computer program and has the characteristics of high precision, high efficiency, high reliability and multiple functions. It is an important tool in machining technology and can achieve precision processing of parts and processing of complex shapes. Compared with traditional machine tools, CNC machine tools have the following significant characteristics:

1. High precision: CNC machine tools can achieve micron-level high-precision processing, greatly improving the size and shape accuracy of parts. At the same time, CNC machine tools also have high repeatability positioning accuracy, which can accurately control the position and direction of the tool relative to the workpiece to avoid machining errors.

2. High efficiency: CNC machine tools can achieve high-speed processing, speeding up workpiece processing speed and production efficiency. And CNC machine tools can automatically change tools, further improving production efficiency.

3. Multiple functions: CNC machine tools have multiple processing functions, such as drilling, milling, turning and sawing, etc. In addition, CNC machine tools can also realize automated processing processes and achieve higher production efficiency.

4. Simplified operation: CNC machine tools are computer controlled and can be operated through an intuitive CNC interface, which reduces the operator's skill requirements and operational difficulty. At the same time, CNC machine tool operation is also safer and more stable.

5. Pursuit of high quality: CNC machine tools pursue product quality, considering processing accuracy, quality, working hours and other multiple perspectives, thereby improving product quality and market competitiveness.

Therefore, CNC machine tools have become important equipment for modern factory production. They can not only improve production efficiency and save human and material resources, but also meet the market's demand for high-precision and high-quality processing, making important contributions to the development of the manufacturing industry.
