Each processing method, there is it processing order, our operators, need to follow its processing order to processing, and can not be chaotic, so that the processed products, causing certain effects, or quality problems, precision machining is one of them, then the order of precision mechanical parts processing is divided into which kinds, the following let me talk to us.
First, the layout of the fine parts processing sequence should be based on the construction of the parts and the blank situation, as well as the positioning clamping needs to think about, the focus is on the rigidity of the workpiece is not destroyed.
1. The processing of the previous process can not affect the positioning and clamping of the next process, the intersection of general fine parts processing process should also be considered.
2. First stop the internal shape of the cavity plus process, and then stop the shape processing process.
3. With the same positioning, clamping or the same knife processing process is best to stop in succession, in order to reduce the number of repeated positioning, the number of tool changes and the number of moving the platen.
4. In the same device to stop multiple processes, should be arranged first on the workpiece rigid destruction of small processes.
Second, the tool is concentrated in the sequence method: is divided into processes according to the tool used, with the same tool to finish processing all the parts on the part can be completed. In the second knife, the third to complete the other parts they can complete. This can reduce the number of tool changes, tighten the empty range time, reduce the unnecessary positioning error.
Third, to process parts in order method:
On the processing of many parts, according to its structural characteristics of the processing part into several parts, such as internal shape, shape, surface or plane. General first processing plane, positioning surface, after processing holes; first processing simple geometric shape, and then processing complex geometric shape; first processing lower precision parts, and then processing higher precision requirements of the parts.
