CNC machine tools are high-performance automatic machining machines. Compared with ordinary machine tools, CNC machines have the following advantages:
It can process complex surfaces that are difficult or impossible to machine in general machine tools, such as complex surface molds, integral turbines, engine blades and other complex parts.
With CNC machine tools, higher precision and consistent quality can be achieved. The CNC machine tool is automatically machined according to a predetermined program. There is no human interference factor, and the machining accuracy can also be corrected and compensated by software. Therefore, it is possible to obtain higher precision and repeatability than the machine tool itself.
CNC machine tools have high productivity. Compared with ordinary machine tools, it can increase productivity by 2 to 3 times, especially for the processing of some complex parts, and the productivity can be increased by a factor of ten or even several.
With wide adaptability and great flexibility, it can adapt to different sizes and specifications. Generally, it can be used to process different workpieces by simply replacing the program with a common fixture. There is almost no need for special tooling fixtures, which greatly shortens the production cycle.
A multi-purpose machine. CNC machine tools, especially machining centers that can automatically change the tool, can finish the machining of all the parts of the part after one clamping. It can replace 5 to 7 ordinary machine tools, saving labor and transportation time, measurement and loading time, and saving plant area.
Less work in progress, which accelerates the turnover of working capital and improves economic efficiency.
It can improve the production environment and greatly reduce the labor intensity of the operator.
It can achieve more accurate cost accounting and production scheduling, is the main equipment for flexible automatic processing, and is the basis for the development of flexible production lines (FMS) and computer integrated manufacturing (CIMS).
