Precise parts processing process route of the general principles, mainly from the following four points:
1, the benchmark first
That is, the first processing of the reference plane, parts in the machining process, as the positioning of the appearance of the first should be processed in order to as soon as possible for the subsequent process of processing to provide fine benchmark.
2, the first face after the hole
For the box, bracket and connecting rod and other parts should be processed after the plane processing hole. This allows the hole to be machined in a flat position to ensure the accuracy of the plane and hole position, and to facilitate the machining of holes in the plane.
3, divided processing stage
Machining quality requirements of high appearance, are divided into processing stage, generally can be divided into rough, semi-finishing and finishing three stages. Mainly in order to ensure the quality of processing; is conducive to scientific application equipment; easy to arrange heat treatment process; and easy to find blank defects and so on.
4, finishing processing
The main appearance of the finishing, such as grinding, honing, grinding, rolling processing, etc., should be placed on the end of the process line. The development of precision parts processing process of the general principles of precision parts processing technology development procedures, can be divided into two links. The first is to develop the process of parts processing, and then determine the process of each process size, equipment and process equipment used and cutting specifications, working hours and so on.
