A CNC processing plant often has several surfaces that need to be processed. These surfaces not only have certain precision requirements, but also have certain orientation requirements between the surfaces. In order to meet these precision requirements, the processing order of each surface of the CNC processing plant cannot be arranged arbitrarily, but must follow certain principles. This is the selection and replacement of the positioning datum to select the processing order, and the previous process prepares the positioning datum for the subsequent process. guidelines. So, next, the cnc processing factory will briefly introduce the important sequence of processing.

1. Before the processing of important surfaces, the precision benchmark should be rested once to ensure the processing accuracy of important surfaces.

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

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

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

5. For the process that is prone to waste products, the finishing and finishing processing can be properly placed in the front, and some non-essential small surface processing can be placed later.

The above content is the important processing sequence summarized by the cnc processing factory for you, and I hope it will be helpful to you.
