For Non-standard Precision shafts, the processing is very strict, and the processing procedures include infeed and outfeed. There are specific requirements for the size and precision, such as 1mm plus or minus how many microns, 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 scrap. This results in an increase in cost, and at the same time, the parts are definitely not usable.

For the processing of precision parts, the main requirements are the size, such as the diameter of the cylinder, there are strict requirements, and the positive and negative errors are within the specified requirements. Requirements, positive and negative errors are also specified, such as a built-in cylinder (take the simplest basic component as an example), if the diameter is too large and exceeds the allowable error range, it will cause the situation that it cannot be inserted. If the actual If the diameter is too small and exceeds the lower limit of the allowable negative value of the error, it will cause the insertion to be too loose and the problem of not firmness will occur. These are all unqualified products, or the length of the cylinder is too long or too short, which exceeds the allowable range of error, and they are all unqualified products, which must be scrapped or reprocessed, which will inevitably increase the cost.

The above are the requirements for the processing of precision parts, which are the most important size issues. It must be processed in strict accordance with the additional drawings. The actual size of the processed will not be exactly the same as the theoretical size of the drawings. However, as long as the processing size is within the error All qualified parts are within the allowable range. Therefore, the requirement for precision parts processing is to process them in strict accordance with the theoretical size.

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. The testing equipment can detect the parts that do not meet the requirements, so that all products sent to customers truly meet the requirements.
