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, if an order is wrong, it is easy to cause great losses. , precision machining is one of them, so what is the order of it?
1, precision machining order should be arranged according to the structure of the part and the blank, as well as the positioning and clamping needs to be considered. The key is not to destroy the rigidity of the workpiece.
(1) the processing of the previous process can not affect the positioning and clamping of the next process, interspersed with the general precision machining process should also be considered comprehensively.
(2) The internal shape and cavity processing process should be carried out first, and then the shape processing process.
(3) It is best to use the same positioning and clamping method or the same tool processing process to reduce the number of repeated positioning, the number of tool changes and the number of times to move the table.
(4) Multiple processes carried out in the same device should be prioritized for processes with less rigid damage to the workpiece. Precision parts processing
Second, the tool concentration sorting method is to divide the process by the tool used, using the same tool to process all the parts that can be completed on the part. Use the second tool, the third tool to do the rest. This can reduce the number of tool changes, compress the idle time and reduce unnecessary positioning errors.
3. Using the machining part sequence method For parts with more machining content, the machined part can be divided into several parts according to its structural characteristics, such as internal shape, external shape, surface or plane. In general, the first processing plane and positioning surface, and then processing holes; first processing simple geometry, and then processing complex geometry; first processing lower precision parts, and then processing higher precision parts. The above is the sequence of precision parts machining. Be sure to follow these steps, which will greatly reduce your processing risk.
