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 defect rate What?For precision parts processing, the main size requirements, such as the diameter of the cylinder, have 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 and strict requirements for length, width and height. There are also provisions for positive and negative errors. For example, if the diameter of an embedded cylinder (take the simplest basic component as an example) is too large and exceeds the allowable range of error, it will cause the situation that it cannot be inserted. If the actual diameter is too large If it exceeds the lower limit of the allowable negative value of the error, the insertion will be too loose and the problem of looseness will occur. 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 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 strictly in accordance with the theoretical dimensions.
