What are the factors to be considered in the selection of surface processing methods for CNC work-pieces?


The processing method of the surface of the CNC work-piece depends first on the technical requirements of the processed surface. However, it should be noted that these technical requirements are not necessarily the requirements specified in the part drawings, and sometimes they may be higher than the requirements on the part drawings in some aspects due to technological reasons. For example, the processing requirements for the surface of some CNC work-pieces are increased due to the misalignment of the benchmarks. Or because it is used as a fine benchmark, higher processing requirements may be imposed on it.

When the technical requirements of the surface of each CNC machined part are clarified, the final processing method that can guarantee the requirements can be selected accordingly, and the processing steps required and the processing steps of each step can be determined. The selected processing method of CNC machining parts should meet the requirements of parts quality, good processing economy and high production efficiency. For this reason, the following factors should be considered when choosing a processing method:

1. The processing accuracy and surface roughness that can be obtained by any CNC processing method have a considerable range, but only in a certain narrow range is it economical, and the processing accuracy in this range is economic processing accuracy. For this reason, when selecting a processing method, the corresponding processing method that can obtain economical processing accuracy should be selected.

2. The nature of the material of the CNC work-piece should be considered.

3. The structural shape and size of the CNC machining parts should be considered.

4. To consider the requirements of productivity and economy. For mass production, high-efficiency advanced technology should be adopted. It can even fundamentally change the manufacturing method of the blank, which can reduce the labor of machining.

5. The existing equipment and technical conditions of the factory or workshop should be considered. When choosing a processing method, the existing equipment should be fully utilized, the potential of the enterprise should be tapped, and the enthusiasm and creativity of the workers should be brought into play. But it should also consider continuously improving existing processing methods and equipment, adopting new technologies and improving process levels.
