    Machining requirements for precision parts

    source: time:2019-10-18 18:13:13

    What are the processing requirements for precision parts?

    For precision parts, the processing is very strict, and the processing procedures include feed, output, etc. There are specific requirements for size and accuracy, such as 1mm plus or minus micrometers. If the size is wrong too much, it will become waste products. At this time, it is equivalent to reprocessing, time-consuming and laborious, and sometimes even the whole processing materials will be scrapped, which results in increased cost. At the same time, the parts are definitely not used.

    For the processing of precision parts, the main requirements are dimension, such as the diameter of cylinder, strict requirements, positive and negative errors within the specified requirements are qualified parts, otherwise they are all unqualified parts; there are specific strict requirements for length, width and height, positive and negative errors are also specified, such as an embedded cylinder (take the simplest basic parts as an example), if straight If the diameter is too large and exceeds the allowable range of error, it will result in the situation that it cannot be inserted. If the actual diameter is too small and exceeds the lower limit of the allowable negative value of error, it will result in the problem that the insertion is too loose and insecure. These are all unqualified products, or the length of the cylinder is too long or too short, which is beyond the allowable range of error. They are all unqualified products, which should be discarded or reprocessed, which will inevitably cause the increase of cost.

    The above is the requirement for precision parts processing, which is the most important dimension problem. It must be processed in strict accordance with the additional drawings. The actual dimension processed will certainly not be the same as the theoretical dimension of the drawings. However, as long as the processing dimension is within the allowable range of error, all parts are qualified. Therefore, the requirement for precision parts processing is strictly in accordance with the theory Dimensions are processed.

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