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.
