When machining, the following four principles should be followed:

 

First, the workpiece after finishing processing: the main surface finishing processing (grinding, honing, finishing, rolling processing, etc.) should be carried out in the final stage of the process, the surface roughness after processing Ra0.8um or more, a slight collision will damage the surface, in Japan, Germany and other countries, after finishing processing are protected with fleece cloth.

 

Second, divide the processing stages: the surface with high quality requirements is divided into processing stages, generally can be divided into three stages: roughing, semi-finishing and finishing. Easy to arrange the main conducive to ensure the processing quality of the reasonable use of equipment heat treatment process, and easy to find the blank defects, etc. 

 

Third, the first processing reference surface: the processing process, the first processing as a positioning reference surface, to provide the correct benchmark for the processing of the later processes. Called the "benchmark first".



Four, before and after the hole: box, bracket and connecting rod and other components, must be processed first plane processing holes. In this way, the hole can be positioned in the plane processing, to ensure the positioning accuracy of the plane and hole, to facilitate the processing of the hole on the plane.
