After determining the processing method of precision mechanical parts, it is necessary to determine the processing procedure according to the type of the part and the machining equipment. It is determined that the processing procedure of precision mechanical parts has two different principles: process concentration and process dispersion. Then these two kinds of processing What are the characteristics of the principle of the process?

1. Features of the principle of process concentration

(1) The use of machine tools and equipment with a high degree of automation is conducive to improving processing efficiency.

(2) The number of processes is reduced, and the machining equipment is also less, which can reduce the number of processing personnel and processing sites.

(3) The number of clamping of the workpiece is reduced, which can shorten the processing time, and multiple workpiece surfaces can be processed in one clamping, which can improve the processing accuracy.

2. The characteristics of the principle of process dispersion

(1) The processing machine tool and fixture are relatively simple, and it is easy to adjust the tool setting.

(2) The technical level of the operators is not high.

(3) The number of processes is large, the number of mechanical processing equipment is increased, the number of processing personnel is also large, and the area of the processing site occupied is also large. 

The principle of process concentration and the principle of process dispersion in the processing of precision mechanical parts have their own characteristics: the principle of process concentration is mainly to perform centralized processing of multiple processes in one clamping, thereby shortening the processing time of precision mechanical parts and improving processing efficiency. ; The principle of process dispersion is mainly to make the processing content of each processing process as simple as possible, so that it is easy to adjust. Therefore, which processing principle should be selected when processing precision mechanical parts, it is necessary to choose according to the type of processing parts.
