Our country's precision parts processing technology has finally broken the technical blockade of developed countries on precision processing equipment, making China a country with independent processing technology for various precision parts after the United States, Germany and Japan.
The precision of parts after precision machining will be quickly lost due to the redistribution of stress. For some parts requiring high machining accuracy. After roughing and before finishing, low temperature annealing or aging process should also be arranged to eliminate internal stress.
Precision machining reflects the strength of industry, and the research on the precision and stability of industrial processing has always been a difficult problem in the field of processing in the world. On this issue, the current processing control method has made some progress, but in the influencing factors and evaluation methods, there are still many applications need to be improved and perfected.
Precision parts processing as a new type of processing technology, has been widely promoted, in the case of judging whether it is suitable, we should first understand its process.
The primary link of precision parts processing is the preparation of production and skills, that is, including the planning and production of skills and special skills and equipment, the preparation of production plans, and the preparation of production data.
