When you get a workpiece, the technology will sequence the processing workers when making the process program card, so do you know what the processing sequence of precision parts is?

For the processing industry, the order is very important, it is related to the quality assurance of the products, if one order is wrong, it is easy to cause a lot of losses. , Precision parts processing is one of them, so what is its order?

1. The arrangement of the machining sequence of precision parts should be considered according to the structure and blank condition of the parts, as well as the needs of positioning and clamping. The key point is that the rigidity of the workpiece is not damaged. 

(1) The processing of the previous process cannot affect the positioning and clamping of the next process, and the processing process of general precision parts interspersed in the middle should also be considered comprehensively. 

(2) The inner shape and inner cavity processing process is carried out first, and then the outer shape processing process is carried out. 

(3) It is best to carry out the same positioning, clamping method or the same tool processing process in order to reduce the number of repeated positioning, the number of tool changes and the number of times of moving the platen. 

(4) For multiple processes carried out in the same installation, the process with little damage to the rigidity of the workpiece should be arranged first.   

2. The tool centralized sorting method is to divide the process according to the tools used, and use the same tool to process all the parts that can be completed on the part. Doing the rest of the way they can with the second knife, the third. This can reduce the number of tool changes, compress the idle time, and reduce unnecessary positioning errors.   

3. Using the processing part sequence method  For parts with a lot of processing content, the processing part can be divided into several parts according to their structural characteristics, such as inner shape, outer shape, curved surface or plane, etc.

Generally, the plane and positioning surface are processed first, and then the hole is processed. 

Process simple geometric shapes first, and then process complex geometric shapes.

The parts with lower precision are processed first, and then the parts with higher precision are processed.

The parts with lower precision are processed first, and then the parts with higher precision are processed.
