The Standard For Precision Parts Processing For precision parts, the processing is very strict, and the processing procedures include cutting in and out. There are specific requirements for the size and accuracy, such as how many microns are plus or minus for 1 mm, etc. If the size is too wrong, it will become a waste product. At this time, it is equivalent to reprocessing, which is time-consuming and laborious, and sometimes even makes the entire processing material scrapped. This has just caused the increase of cost, and at the same time, the parts are definitely unusable. So what standards and requirements should be followed in the processing of precision parts? For the processing of precision parts, there are mainly dimensional requirements, such as the diameter of the cylinder, there are strict requirements, and the positive and negative errors are within the specified range to be qualified parts, otherwise they are unqualified parts; there are also specific and strict requirements for length, width and height. Positive and negative errors are also regulated, such as an embedded cylinder (take the simplest basic parts as an example), if the diameter is too large, exceeding the allowable range of error, it will cause the situation that it cannot be inserted, if the actual diameter is too large Small, if it exceeds the lower limit of the allowable negative value of the error, it will cause problems that the insertion is too loose and not firm. These are unqualified products, or the length of the cylinder is too long or too short, beyond the allowable range of error, they are all unqualified products and must be scrapped or reprocessed, which will inevitably increase the cost.
