What are the points you must know about precision parts processing?

u200b Precision machining is a very strict process. Regardless of whether it is for cutting or other processes, or for accuracy and size, it is a process that requires very strict requirements. Then, when machining precision parts, what requirements and standards must be followed to ensure low or even zero defects Rate?u200b For precision parts processing, 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 requirements to be qualified parts, otherwise they are unqualified parts; there are also specific strict requirements for length, width and height. , There are also regulations for positive and negative errors, such as an in-line cylinder (take the simplest basic component as an example). If the diameter is too large and exceeds the allowable range of error, 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, and exceeds the allowable error range. They are all unqualified products. They must be discarded or reprocessed, which will inevitably increase the cost. 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. The requirement of precision parts processing is actually the most important size problem. It must be processed strictly in accordance with the additional drawings. The actual size of the processing will definitely not be exactly the same as the theoretical size of the drawing, but as long as the processing size is within the allowable range of error There are qualified parts inside, so the requirement for precision parts processing is to process in strict accordance with the theoretical dimensions.
