Non-standard precision parts processing, with high precision requirements

We know that the processing of non-standard precision parts has high requirements for precision, so what should be paid attention to in the process of precision processing, and Concord will introduce to you below:

The precision must be processed in strict accordance with the additional drawings, and the processing size is within the allowable range of error, which is a qualified part, so the requirement for processing precision parts is to process strictly according to the theoretical size.

The processing of precision parts is mainly about size requirements, such as the diameter of a cylinder, there are strict requirements, and the positive and negative errors are within the range required by the rules to be qualified parts, otherwise they are all unqualified parts; the length, width and height are also detailed. Requirements, positive and negative errors also have rules, such as an embedded cylinder, if the diameter is too large, beyond the allowable range of error, it will not be inserted into the situation, if the actual diameter is too small, exceeding the lower limit of the allowable negative value of the error , It will cause the problem that the insertion is too loose and not tight.

These are unqualified products, which will be scrapped or reprocessed, which will inevitably increase the cost. Therefore, it is very important to ensure the accuracy of non-standard precision parts processing.
