What Is The Order Of Precision Machining?

What is the order of precision machining?
What is the order of precision parts processing? For the processing industry, the order is very important, it is related to the quality assurance of the product, there is a wrong order, it is easy to cause a lot of losses, serious words to start again, a little serious, is that these products are scrapped, precision machining is one of them, so what is its order?
1. The arrangement of precision machining sequence should be considered according to the structure of the parts and the blank condition of the parts, as well as the need of positioning and clamping, and the focus is that 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, and the general precision machining process interspersed in the middle should also be considered comprehensively.
(2) First, the inner shape and inner cavity addition process, and then the shape processing process.
(3) It is best to connect to the same positioning, clamping mode or the same knife processing process, so as to reduce the number of repeated positioning times, change the knife times and move the pressure plate times.
(4) In the same installation of multiple processes, we should first arrange the small destruction of the rigidity of the workpiece process. Precision parts processing
2. Tool centralized sequence method is to divide the process according to the use tool, with the same tool to process all the parts can be completed. At the other parts that they can do with the second knife and the third one. This can reduce the number of knife changes, compress the empty-range time, and reduce the unnecessary positioning error.
3. For the processing content of many parts, the processing part can be divided into several parts according to its structural characteristics, such as inner shape, shape, curved surface or plane. Generally, process the plane and the positioning surface before machining the simple geometry shapes and then the complex geometry shapes; the parts with low accuracy and the parts with high accuracy. The above is the order of precision parts processing, must be operated in accordance with these several, which will make your processing risk greatly reduced.
