We know that the precision of non-standard precision parts processing is higher, then what should be noted in the precision machining process? The following is for us to introduce.
The precision of the non-standard precision parts mentioned here must be strictly processed in accordance with the additional drawings. The processing dimensions are all qualified parts within the allowable range of error, so the requirements for processing precision parts are strictly in accordance with theoretical dimensions. .
The processing of precision components is mainly a size requirement, such as the diameter of the cylinder, and strict requirements. Positive and negative errors are qualified parts within the specified requirements. Otherwise, they are all unqualified parts; the length, width and height are also specific. Strictly speaking, the positive and negative errors are also stipulated. For example, an embedded cylinder, if the diameter is too large and exceeds the allowable range of error, it will cause the situation that the insertion cannot be entered. If the actual diameter is too small, the allowable negative limit is exceeded. It will cause too loose and insecure problems.
These are unqualified products that are either to be scrapped or reworked, which inevitably results in increased costs. Therefore, it is very important to ensure the accuracy of non-standard precision parts processing
