Those who know about precision parts machining know that precision machining is a very strict process, whether for tool walking or other processes, or accuracy, size are quite strict requirements of the process. So precision parts processing, in the end to follow what requirements and standards to ensure low or even zero defect rate? The following is my introduction to the specific requirements and standards for precision parts processing.
For precision parts processing is mainly dimensional requirements, such as how much the cylindrical diameter, there are strict requirements, positive and negative error within the specified requirements to be qualified parts, otherwise they are unqualified parts; length, width and height also have specific strict requirements, positive and negative error is also specified, such as an embedded cylinder (take the most simple basic parts for example), if the diameter is too large, more than the error allowed range, it will Caused by, insert not into the situation, if the actual diameter is too small, more than the lower limit of the negative value of the error allowed, it will cause inserted too loose, not solid problems occur. These are unqualified products, or the cylindrical length is too long or too short, beyond the error tolerance range, are unqualified products, are to be scrapped, or re-processed, which will inevitably cause the cost increase.
Second is the advanced precision parts processing equipment and testing equipment, advanced processing equipment makes the processing of precision parts easier, higher precision, better results. Testing equipment can detect the parts that do not meet the requirements, so that all the products sent to customers really meet the requirements.
Precision parts processing requirements is in fact the main size problem, must be strictly in accordance with another plus drawings for processing, processing out of the actual size will certainly not be the same as the theoretical size of the drawings, only, as long as the processing size within the error allowed are qualified parts, so the requirements of precision parts processing is in strict accordance with the theoretical size for processing.
