For precision parts, processing is very strict, and the processing procedures include cutting in and out. There are specific requirements for size and accuracy, such as 1mm plus or minus micrometers, etc. If the size is too large, it will become waste.
At this time, it is equivalent to reprocessing, which is time-consuming and laborious, and sometimes even makes the entire processed material scrapped. This has caused an increase in cost, and at the same time, the parts are definitely unusable.
The processing of precision parts is mainly based on the size requirements, such as the diameter of the cylinder, there are strict requirements, and the positive and negative errors are within the specified requirements to be qualified parts, otherwise they are unqualified parts; the length, width and height are also specific and strict Requirements, positive and negative errors are also specified, such as an in-line cylinder (take a simple 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 diameter If it is too small, if it exceeds the lower limit of the allowable negative value of the error, it will cause the problem of too loose and weak insertion. These are unqualified products, or the length of the cylinder is too long or too short, which exceeds the allowable range of error. They are all unqualified products. They must be discarded or reprocessed, which will inevitably increase the cost.
The above precision machining manufacturers are the requirements for precision parts processing, which is the most important size problem. They must be processed strictly in accordance with the additional drawings. The actual size of the processing will certainly not be exactly the same as the theoretical size of the drawing, but only The machining dimensions are qualified parts within the allowable range of error. Therefore, the requirement for precision parts machining is to process strictly in accordance with the theoretical dimensions.
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. Testing equipment can detect parts that do not meet the requirements, so that all products sent to customers can truly meet the requirements.
