There are often several surfaces that need to be processed on a CNC processing plant. These surfaces not only have certain accuracy requirements themselves, but also have certain orientation requirements between the surfaces. In order to meet these accuracy requirements, the processing sequence of each surface of CNC processing parts cannot be arranged arbitrarily, but must follow certain principles. This is the selection and replacement of positioning datums that determine the processing sequence, and the previous process prepares the positioning datums for subsequent processes. criteria. Therefore, Xiehe Processing Factory will briefly introduce to you the important sequence of processing.

1. Before processing important surfaces, the fine datum should be rested to ensure the processing accuracy of important surfaces.

2. After the fine reference machining is completed, rough machining, semi-finishing and finishing should be carried out on each main surface with higher precision requirements. Surfaces with particularly high precision requirements also require finishing processing.

3. The surface as a precision reference should be processed at the beginning of the CNC processing plant process, because it will be used for positioning when processing other surfaces in subsequent processes. That is, "baseline first, others later".

4. When processing the fine datum plane, it is necessary to use the rough datum positioning. In single piece, small batch production, or even batch production, for castings and forgings with complex shapes or large specifications, as well as blanks with large specification errors, the marking process should be organized first before the machining process to provide a precise benchmark. Processing supplies alignment standards.

5. For processes that are prone to waste products, finishing and finishing can be appropriately placed at the front, and some non-essential small surface processing can be placed at the back.
