The machining method of CNC machining parts depends first on the technical requirements of the machined surface. However, it should be noted that these technical requirements may not necessarily be the requirements specified on the part drawing, and sometimes may be higher than the requirements on the part drawing in some aspects due to technological reasons. If the machining requirements for certain CNC machined parts are increased due to non overlapping benchmarks. Or, due to being used as a precision benchmark, higher processing requirements may be placed on it.

CNC machining usually refers to precision mechanical machining controlled by computer digitization, such as CNC machining lathes, CNC milling machines, CNC machining boring and milling machines, etc. CNC precision machining, integrating industry resources, utilizing raw materials such as casting, forging, powder metallurgy, and extruded profiles to reduce costs.

The surface processing method of CNC machined parts first depends on the technical requirements of the processed surface. However, it should be noted that these technical requirements may not necessarily be the requirements specified on the part drawing, and sometimes may be higher than the requirements on the part drawing in some aspects due to technological reasons. If the machining requirements for certain CNC machined parts are increased due to non overlapping benchmarks. Or, due to being used as a precision benchmark, higher processing requirements may be placed on it.

The surface processing method of CNC machined parts first depends on the technical requirements of the processed surface. However, it should be noted that these technical requirements may not necessarily be the requirements specified on the part drawing, and sometimes may be higher than the requirements on the part drawing in some aspects due to technological reasons. If the addition of certain CNC machining surfaces is increased due to non overlapping benchmarks, the following factors should be considered when selecting the machining method:

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

2. Consider the properties of CNC machined parts materials.

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

4. Consider productivity and economic requirements. When producing in large quantities, efficient and advanced processes should be adopted. It can even fundamentally change the manufacturing method of the blank, reducing the labor required for mechanical processing.
