Production and processing principles of precision parts processing
In the process of precision parts processing, there will be many product workpieces that are not produced at one time, and when the product workpieces are produced, they are only a rough model. If the factory becomes a real product, it needs to use some mechanical equipment for precision processing, and carry out precision processing according to different product requirements, and finally become a product with use value.
In order to ensure the efficiency of precision machining and the quality of products produced, four principles must be followed in precision machining.
1. First benchmarking:
When using mechanical equipment to process products, a datum plane must be determined to provide positioning reference in subsequent production and processing.
2. Division of production and processing stages:
When precision machining products, different production and processing levels are required for different product requirements, and the production and processing levels need to be divided. If the precision requirement is not high, then the simple rough machining stage is OK. The construction period of products is becoming more and more strict, and semi finishing and finishing will be carried out later.
3. Face before hole:
During precision machining, for product workpieces such as supports, both plane production and machining are required. In order to process the machining hole with small accuracy error, first make the machining plane, and then make it. Machining holes helps reduce errors.
