Factors to consider when selecting surface processing methods for CNC machined parts

The processing method for the surface of machined parts at Dongguan CNC Precision Machining Factory first depends on the technical requirements of the processed surface. However, it should be noted that these technical requirements may not necessarily be specified on the part drawing. Sometimes, due to technical reasons, they may be higher than the requirements on the part drawing in some aspects. For example, due to misalignment of the benchmark, the machining requirements for some CNC workpiece surfaces have increased. Alternatively, as a precision benchmark, higher machining requirements may be proposed.

After clarifying the technical requirements for each CNC machining part surface, the final machining method that can ensure the requirements can be selected based on this, and several work steps and the machining method for each work step can be determined. The machining method selected for CNC machining parts should meet the requirements of part quality, good machining economy, and high production efficiency. For this reason, the following factors should be considered when selecting processing methods:

1. Any CNC machining method can achieve a considerable range of machining accuracy and surface roughness, but only within a very narrow range is economic, and the machining accuracy within this range is economic machining accuracy. Therefore, when selecting processing methods, the corresponding processing methods that can achieve economic processing accuracy should be selected.

2. Consider the characteristics of CNC workpiece materials.

3. The structural shape and size of CNC workpieces should be considered.

4. Consider productivity and economic requirements. High efficiency and advanced technology should be adopted for mass production. It can even fundamentally change the manufacturing method of the blank, thereby reducing the labor required for mechanical processing.

5. The existing equipment and technical conditions of Dongguan CNC Precision Processing Plant should be considered. When selecting processing methods, it is necessary to fully utilize existing equipment, tap into the potential of the enterprise, and unleash the enthusiasm and creativity of workers. However, continuous improvement of existing processing methods and equipment, adoption of new technologies, and improvement of process level should also be considered.
