What is the processing sequence of precision parts? In the processing industry, order is very important, which is related to the quality assurance of products. If the order is wrong, it is easy to cause great losses. If it is serious, it should be repeated. If it is a little serious, these products will be scrapped. Precision machining is one of them. What is the order?
1、 The arrangement of precision machining sequence shall be considered according to the structure and blank condition of the parts, as well as the needs of positioning and clamping, with the emphasis on the rigidity of the workpiece not being damaged.
(1) The processing of the previous process shall not affect the positioning and clamping of the next process, and the general precision machining process interspersed between them shall also be comprehensively considered.
(2) The internal cavity processing sequence is carried out first, and then the contour processing sequence is carried out.
(3) It is better to connect the processes of the same positioning, clamping method or the same knife processing to reduce the times of repeated positioning, tool change and moving the pressing plate.
(4) For multiple processes in the same installation, the process with small rigid damage to the workpiece shall be arranged first. Precision parts processing
2、 The centralized tool sorting method is to divide the working procedure according to the tool used, and use the same tool to process all the parts that can be completed on the part. Use the second knife and the third knife to complete other parts that they can complete. This can reduce the number of tool changes, compress the idle time and reduce unnecessary positioning errors.
3、 For parts with a lot of processing content, the processing part can be divided into several parts according to its structural characteristics, such as internal shape, shape, curved surface or plane. Generally, the plane and positioning surface are processed first, and then the hole is processed; First process simple geometric shapes, then process complex geometric shapes; The parts with lower accuracy shall be processed first, and then the parts with higher accuracy requirements shall be processed. The above is the processing sequence of precision parts. You must follow these steps to reduce your processing risk.
