What are the processing requirements for precision parts?

For precision parts, processing is very strict, and the processing procedures include cutting in and out. There are specific requirements for size and accuracy, such as 1mm plus or minus micrometers, etc. If the size is too large, it will become waste. At this time, it is equivalent to reprocessing, which is time-consuming and labor-intensive, and sometimes even makes the entire processed material scrapped. This has caused an increase in cost, and at the same time, the parts are definitely unusable.
Precision parts processing is mainly based on the size requirements, such as the diameter of the cylinder, there are strict requirements, and the positive and negative errors are within the specified requirements. Negative errors are also stipulated, such as an in-line cylinder (take the simplest basic component as an example). If the diameter is too large and exceeds the error tolerance, it will cause the situation that it cannot be inserted. If the actual diameter is too small If the lower limit of the allowable negative value of the error is exceeded, the insertion will be too loose and the problem of not firmness will occur. These are unqualified products, or the length of the cylinder is too long or too short, which exceeds the allowable error range. They are all unqualified products. They must be discarded or reprocessed. This will inevitably increase the cost.
The requirement of precision parts processing is actually the most important size problem. It must be processed strictly in accordance with the additional drawings. The actual size of the processing will certainly not be exactly the same as the theoretical size of the drawing, as long as the processing size is within the allowable error range. Qualified parts, therefore, the requirement for precision parts processing is to process in strict accordance with the theoretical dimensions.
  The second is advanced precision parts processing equipment and testing equipment. Advanced processing equipment makes it easier to process precision parts, with higher precision and better results. Testing equipment can detect parts that do not meet the requirements, so that all products sent to customers can truly meet the requirementsPrevious: What are the measurement methods for precision cnc machining parts ?Next: There are many precautions in the process of precision parts processing
