Cnc machining parts surface processing method selection factors to consider


The surface processing method of cncmachined parts depends first 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 parts drawing, and may sometimes be higher than the requirements on the part drawing in some respects due to process reasons. If the benchmarks do not coincide, the processing requirements for the surface of some cnc machined parts are increased. Or because of being a fine benchmark, it is possible to impose higher processing requirements on it.

Once the technical requirements for the surface of each cnc machined part are specified, the final machining method that guarantees this requirement can be selected accordingly, and the machining method that requires several steps and steps is determined. The selected cnc machined parts processing method should meet the requirements of part quality, good processing economy and high production efficiency. To this end, the following factors should be considered when choosing a processing method:

1. Any kind of cnc processing method can obtain a considerable range of processing accuracy and surface roughness, but only in a narrow range is economical, the processing precision of this range is economic processing precision. For this reason, when selecting a processing method, the corresponding processing method that can obtain economic processing precision should be selected.

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

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

5. Consider the existing equipment and technical conditions of the cnc processing plant or workshop. When selecting the processing method, you should make full use of the existing equipment, tap the potential of the enterprise, and give full play to the enthusiasm and creativity of the workers. However, consideration should also be given to continually improving existing processing methods and equipment, adopting new technologies and improving process levels.
