Regarding the surface processing of CNC precision parts processing, when we perform surface processing of CNC precision parts processing, it first depends on the technical requirements of the processed surface, but it should be noted that these technical requirements are not necessarily the requirements stipulated in the part drawings. Sometimes It may also be higher than the requirements on the part drawing in some aspects due to technological reasons. For example, due to the misalignment of the datum, the processing requirements for the processing surface of some CNC precision parts are increased. Or because it is used as a fine benchmark, higher processing requirements may be imposed on it.
When the technical requirements for the machining surface of each CNC precision part are clarified, the final processing method that can guarantee the requirements can be selected accordingly, and the processing steps that require several steps and each step can be determined. The selected CNC precision parts processing method should meet the requirements of parts quality, good processing economy and high production efficiency.
After we understand the above consultation, we should consider the following factors when we understand CNC machining
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 materials processed by CNC precision parts should be considered.
3. The structural shape and size of CNC precision parts processing 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.
