There are often several surfaces that need to be processed on a CNC processing workpiece. These surfaces not only have accuracy requirements, but also have certain orientation requirements on each surface. In order to meet these accuracy requirements, the processing order of the surface of the CNC processing parts cannot be arranged at will, but it is necessary to comply with the inevitable criteria. This is the selection and conversion of the positioning benchmark. Code.
What are the importance of CNC processing order::
1. Before the surface processing, a break should be performed on the essence to facilitate the processing accuracy of important surface processing.
2. After the fine -founded processing is well processed, then the surface with higher accuracy requirements is carried out for rough processing, semi -precision processing and fine processing. The precision requires a particularly high surface. Lighting is needed.
3. The surface of the precision standard should be processed at the beginning of the CNC processing process. It should be located when processing other surfaces in subsequent processes. That is "the benchmark before other".
4. When machining the precision surface, you need to use a thick benchmark. In single -piece, small batch production, and even batch production, casting and forging parts with complex shapes or large scale, as well as gluttonous blanks that are overwhelming, should be arranged before the mechanical processing process. Processing provides a positive benchmark.
