Hello, everyone, I am Xiaobian. Today, I will introduce precision parts processing. The following content is organized by Xiaobian, and the relevant content is for reference.

Precision Parts Machining - Beryllium copper _016 Round hole _ coaxiality 0002

For the processing industry, the order is very important, it is related to the product quality assurance, there is a wrong order, it is easy to cause a lot of losses, serious words to start over, a little serious, is that these products are scrapped, precision parts processing is one of them, so what is the order of it?

First, the arrangement of precision parts processing sequence should be considered according to the structure and blank status of the parts, as well as the needs of positioning clamping, the focus is on the rigidity of the workpiece is not destroyed.

(1) The processing of the previous process should not affect the positioning and clamping of the next process. The processing of universal precision parts interspersed with the process should also be considered comprehensively.

(2) Advance the machining sequence of the inner shape and cavity, and then carry out the shape machining process.

(3) It is best to connect the same positioning, clamping mode or the same knife processing process to reduce the number of repeated positioning, the number of tool change and the number of moving plate.

(4) In the same installation of multiple processes, should be arranged first to the workpiece rigid damage small process. Precision parts processing.

Two, the tool concentration sequencing method is according to the tool used to divide the process, with the same tool to finish the parts of all can be completed. With a second knife and a third knife to do whatever else they can. This can reduce the number of tool changes, compress the space time, reduce unnecessary positioning errors.

Three, the processing parts sequencing method for processing a lot of parts, according to the structural characteristics of the processing part is divided into several parts, such as inner shape, shape, surface or plane. Generally first processing plane, positioning surface, after processing holes; First processing simple geometric shapes, then processing complex geometric shapes; Machining the parts with lower precision first, and then machining the parts with higher precision requirements. The above is the order of precision parts processing. We must operate in accordance with these several lines, which will greatly reduce your processing risk.
