Specific requirements and standards for precision parts processing:
On the premise of ensuring the quality of precision die parts, according to the specific conditions of production, we should try our best to improve production efficiency and reduce production.
Cost, formulate reasonable processing technology. In order to improve the production efficiency of precision die parts processing, first of all, we must carefully analyze the processed parts.
The parts are made clear of the material, structural characteristics, tolerance requirements of shape and position, roughness, heat treatment and other technical requirements of the parts.
For precision parts processing, the main dimension requirements, such as the diameter of the cylinder, there are strict requirements, positive and negative errors in the gauge.
The qualified parts are within the specified requirements, otherwise they are all unqualified parts; the length, width and height also have specific strict requirements, and the positive and negative errors are also regulated.
Fixed, such as an embedded cylinder (take the simplest basic parts for example), if the diameter is too large to exceed the allowable error range, then
If the actual diameter is too small and exceeds the lower limit of the allowable negative error, the insertion will be too loose.
Insufficient problems occur. These are all substandard products, or the length of the cylinder is too long or too short, beyond the allowable range of errors.
Unqualified products must be scrapped or reprocessed, which will inevitably lead to increased costs.
In fact, the requirement of precision parts processing is the most important dimension problem. It must be processed strictly according to the additional drawings.
The actual size will not be the same as the theoretical size of the drawings, but as long as the processing size is within the allowable range of error.
It is qualified parts, so the requirement of precision parts processing is to process according to the theoretical size strictly.
