What is the process of precision parts machining?

Only in accordance with the step-by-step process can get better results, especially when machining precision parts, so we have to understand these. Today I will come to learn with you what the process of precision parts advance cnc machining is, as follows:

First, The arrangement of the machining sequence of precision parts should be considered according to the structure of the parts and the status of the blanks, as well as the needs of positioning and clamping. The important point is that the rigidity of the workpiece is not destroyed.
1. The machining of the previous process cannot affect the positioning and clamping of the next process, and the machining of general precision parts should be considered comprehensively.
2. Carry out the inner cavity adding process first, and then the outer shape machining process.
3. It is better to connect the same positioning, clamping method or the same tool advance cnc machining process to reduce the number of repeated positioning, tool change and moving platen times.
4. For the multiple processes carried out in the same installation, the process should be arranged with less rigid damage to the workpiece.

Second, tool centralized sorting method Dongguan parts machining is to divide the processes according to the tools used, and use the same tool to process all the parts that can be completed. Use the second knife and the third knife to complete other parts they can complete. This can reduce the number of tool changes, reduce idle time, and reduce unnecessary positioning errors.

Third, Sorting method by machining parts For parts with many machining contents, the advance cnc machining parts can be divided into several parts according to their structural characteristics, such as inner shape, shape, curved surface or plane. Generally, the plane and positioning surface are processed first, and then the hole is processed; the simple geometric shape is processed first, and then the complex geometric shape is processed; the parts with lower precision are processed first, and then the parts with higher precision are processed.
