How to choose the surface machining method of cnc machined parts

The machining method of cnc machined surface depends on the technical requirements of the machined 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 due to technical reasons. For example, because the benchmarks do not coincide, the cnc machining requirements for the surface of some cnc machining parts are increased. Or it may require higher processing requirements because it is used as a fine benchmark.

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

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

2. To consider the nature of cnc machined material.

3. Consider the structural shape and size of cnc machined parts.

4. Consider productivity and economic requirements. When mass production is carried out, high-efficiency advanced technology should be adopted. It is even possible to fundamentally change the manufacturing method of the blank, which can reduce the labor of machining.

5. It is necessary to consider the existing equipment and technical conditions of the factory or cnc machining shop. When selecting the processing method, it should make full use of the existing equipment, tap the potential of the enterprise, and give play to the initiative and creativity of the workers. However, it should also consider continuously improving existing processing methods and equipment, adopting new technologies and improving technological levels.
