What are the processing sequences for precision mechanical parts?

Each processing method has its own processing sequence, and our operators need to process according to its processing sequence, rather than randomly. This will have a certain impact on the processed products or quality issues. Precision mechanical processing is one of them, so what are the processing sequences of precision mechanical parts.

The arrangement of precision parts processing should be considered based on the structure of the parts, the condition of the blank, and the need for positioning and clamping, with the focus on ensuring that the rigidity of the workpiece is not damaged.

1. The processing of the previous process should not affect the positioning and clamping of the next process, and if there are general precision parts processing processes intersecting in the middle, comprehensive consideration should also be given;
2. Stop the machining process of the inner shape and cavity first, and then stop the contour machining process;
3. It is best to connect and stop the processes processed with the same positioning, clamping method, or the same knife to reduce the number of repeated positioning, tool replacement, and moving the pressure plate. Shenzhen Machinery Processing;
4. Multiple processes that stop in the same device should be arranged first to minimize the rigid damage to the workpiece.

Tool centralized sorting method: It is to divide the processes according to the tools used, and use the same tool to process all the parts that can be completed. Using the second and third knives to complete other parts that they can complete. This can reduce the number of tool changes, shorten the idle time, and reduce unnecessary positioning errors.

Sorting by processing parts: For parts with a lot of processing content, the processing parts can be divided into several parts according to their structural characteristics, such as internal shape, external 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; First process the parts with lower accuracy, and then process the parts with higher accuracy requirements.
