The machining method for the surface of precision CNC machined 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 in the part drawing, and sometimes may be higher than the requirements on the part drawing due to process reasons. If the machining requirements for the surface of certain CNC machined parts are increased due to the misalignment of benchmarks. Or it may be subject to higher processing requirements due to being used as a precision benchmark.
After clarifying the technical requirements for the surface of each CNC machined part, the final machining method that can ensure the requirements can be selected based on this, and the required number of steps and the machining methods for each step can be determined. The selected CNC machining method should meet the requirements of part quality, good machining economy, and high production efficiency. Therefore, when choosing a processing method, the following factors should be considered:
1. Any CNC machining method can achieve a considerable range of machining accuracy and surface roughness, but only within a narrow range is it economical. The machining accuracy within this range is called economic machining accuracy. Therefore, when choosing a processing method, the corresponding processing method that can achieve economic processing accuracy should be selected.
2. Consider the properties of the CNC machining material.
3. Consider the structural shape and size of the CNC machined parts.
4. Consider productivity and economic requirements. When producing in large quantities, high-efficiency advanced processes should be adopted. Even fundamentally changing the manufacturing method of blanks can reduce the amount of labor required for mechanical processing.
5. Consider the existing equipment and technical conditions of the factory or workshop. When selecting processing methods, make full use of existing equipment, tap into the potential of the enterprise, and unleash the enthusiasm and creativity of workers. But it is also necessary to consider continuously improving existing processing methods and equipment, adopting new technologies, and improving the level of craftsmanship.
