The machining method of CNC machining surface, first, depends on the technical of machining surface. However, it should be noted that these technical requirements are not necessarily the requirements specified in the detail drawing, and sometimes may be higher than the requirements in a certain aspect due to technical reasons. For example, due to the benchmark does not coincide so improve CNC machining surface requirements. Or as a result of being used as a precision benchmark may be put forward to its higher processing requirements.
After the technical requirements for the surface of each CNC workpiece are defined, the final machining method that can guarantee the requirements can be selected accordingly. The selected CNC machining method should meet the requirements of part quality, machining economy and production efficiency. For this reason, the following factors should be taken into consideration when selecting processing methods:
The machining accuracy and surface roughness obtained by any CNC machining method have a considerable range, but only in a narrow range is economic, and the machining accuracy of this range is the economic machining accuracy. Therefore, when selecting the processing method, the corresponding processing method that obtain the economical processing precision should be selected.
Consider the properties of CNC workpiece materials.
The structural shape and size of CNC machining parts should be considered.
Consider productivity and economic requirements. Advanced technology with high efficiency should be adopted in mass production. It can even fundamentally change the manufacturing method of the blank and reduce the amount of labor for machining.
The existing equipment and technical conditions of the factory or workshop shall be taken into consideration. When selecting processing methods, the existing equipment shall be fully utilized to tap the potential of the enterprise and give play to the initiative and creativity of the workers. At the same time, continuous improvement of existing processing methods and equipment, adoption of new technologies and improvement of technological level.
