For precision parts, the processing is very strict. The processing procedures include feeding, discharging, etc. there are specific requirements for size and accuracy, such as 1mm plus or minus microns.

The processing of precision parts mainly depends on the dimensional requirements, such as the diameter of the cylinder. There are strict requirements. Only when the positive and negative errors are within the specified requirements are qualified parts, otherwise they are unqualified parts. There are also specific and strict requirements for length, width and height, and the positive and negative errors are also specified. For example, if the diameter of an embedded cylinder is too large and exceeds the allowable error range, it will not be inserted. If the actual diameter is too small and exceeds the lower limit of the allowable negative value of the error, it will cause too loose and unstable insertion. These are unqualified products, or the length of the cylinder is too long or too short, which exceeds the allowable range of the error. They are unqualified products and must be discarded or reprocessed, which will inevitably increase the cost.

As like as two peas, the above is the requirement for the processing of precision parts, mainly the size problem. We must strictly follow the additional drawings, and the actual size of the machining will not be exactly the same as the theoretical size of the drawings. However, as long as the machining dimensions are within the allowable error range, they are all qualified parts, so the requirement of precision parts machining is to process in strict accordance with the theoretical dimensions.

The second is the advanced precision parts processing equipment and testing equipment. The advanced processing equipment makes the processing of precision parts simpler, higher precision and better effect. The testing equipment can detect the parts that do not meet the requirements, so that the products sent to customers can really meet the requirements.
