When you get a workpiece, the technology will list the processing procedures when making the process card, so do you know the order of precision parts processing? For the processing industry, the order is very important. It is related to the quality of the products. If the order is wrong, it is easy to cause a lot of losses. If it is serious, it must be restarted. If it is a bit serious, these products will be scrapped. , Precision parts processing is one of them, so what is its order?
1. The arrangement of the processing sequence of precision parts should be considered according to the structure of the part and the condition of the blank, as well as the need for positioning and clamping. The important point is that the rigidity of the workpiece is not destroyed.
(1) The processing of the previous process cannot affect the positioning and clamping of the next process, and the processing of general precision parts should also be considered comprehensively.
(2) First, carry out the inner shape and inner cavity adding process, and then carry out the shape processing process.
(3) The processes of machining with the same positioning, clamping mode or the same tool are generally connected to reduce the number of repeated positioning, tool change times and the number of times of moving the platen.
(4) For the multiple processes carried out in the same installation, the process should first be arranged with less rigid damage to the workpiece.
