Advantages of CNC Machining:

1 high processing precision,

Through numerical control, it reduces its influence on the unstable factors of manual operation and improves the machining accuracy. Through the digital analysis of the parts, the selection of the tool, fixture selection and the determination of the tool point, the tool change point and the processing amount have made the process reach a high level.

2 high production efficiency

When processing the same required workpiece, the number of stages used by various machine tools is different. Usually, the ratio of HB when the machine tool needs to be used to the machine and the HA when the Cnc Machine tool is used is called the machining complexity coefficient. The more complicated and accurate the workpiece is. The higher the value, the higher the value, the workpiece with the same requirements. Because of the different functions of the selected CNC machine tools, the investment cost of the single machine tool is also different. Usually, the ratio of the investment cost of the CNC machine tool to the investment rate of the ordinary machine tool FB is called For the investment ratio of the machine tool, B=FA/FB, the more functions of the CNC machine tool, the higher the price, the larger the B value.

3 good economic benefits

When using ordinary machine tools that do not need special tooling, the production preparation cost and replacement cost are lower than those of CNC machine tools because there is no programming and verification cost; when the production batch is smaller than the minimum economic batch processed by CNC machine tools, its single piece The cost of the process is lower than that of the CNC machine tool. When the production batch is larger than the minimum economic batch of CNC machine tool processing, and the workpiece processing requirements are complex and the precision requirements are high, that is, when the C value is large, the CNC machine tool is not required to be equipped with a special process. High productivity with equipment and machine tools, the cost per piece of process is lower than that of ordinary machine tools; in small and medium-sized production, compared with the cost of ordinary machine tools equipped with special process equipment, CNC machine processing due to production preparation costs and batch replacement The preparation cost is low, so the cost per piece of the process is also low. Therefore, the use of CNC machine tools to mass produce products can reduce costs and achieve good economic returns.
