Advantages of CNC processing

CNC machining is also called numerical control machining

Before programming, it is necessary to analyze the process of the processed parts, draw up the processing plan, select the appropriate tool, and determine the cutting parameters. In programming, some technological problems such as tool setting and machining route need to be dealt with. Therefore, the process analysis in programming is very important. When processing parts on ordinary machine tools, the operation procedure of each process is specified by the process specification or process card, and the operator processes the parts according to the steps specified in the process card. When machining parts on CNC machine tools, it is necessary to program all the technological process, technological parameters and displacement data to control the machining of machine tools. The processing technology of NC machine tool is basically the same as that of ordinary machine tool in principle, but the whole process of NC machining is automatic, so it has its own advantages

1. Reduce the number of tooling, add the complex shape of Du parts, do not need complex tooling. If Dao wants to change the shape and size of parts, it only needs to modify the processing program of parts, which is suitable for the development and modification of new products.
2. The machining quality is stable, the machining accuracy is high, and the repetition accuracy is high, which can meet the machining requirements of aircraft.
3. In the case of multi variety and small batch production, the production efficiency is high, which can reduce the time of production preparation, machine adjustment and process inspection, and reduce the cutting time due to the use of the best cutting quantity.
4. It can process complex surface which is difficult to be processed by conventional methods, and even process some parts which cannot be observed.
5. The arrangement of working steps is more detailed

This is because the problems that need not be considered in the processing technology of ordinary machine tools, such as the arrangement of working steps in the process, the determination of tool setting point, tool changing point and processing route, can not be ignored when compiling the processing technology of CNC machine tools.

6. CNC machining has high efficiency, high machining accuracy, low labor intensity and strong adaptability to different workpieces.
