Dimensional requirements for precision parts processing

For precision parts, the processing is very strict, and the processing procedures include cutting, cutting and so on. There are specific requirements for size and accuracy, such as how much μm is 1mm plus or minus. If the size is too large, it will become waste. At this time, it is equivalent to reprocessing, which is time-consuming and labor-intensive, and sometimes even causes all The processing of raw materials is damaged, which leads to an increase in cost. In addition, the parts are undoubtedly unusable.

　　 For precision parts processing, the main size requirements, such as the diameter of the cylinder, have strict requirements. The positive and negative difference is within the required range to be considered as qualified parts, otherwise all parts are not qualified; the size also has specific and strict requirements There are also requirements for positive and negative differences. For example, an embedded cylinder (take a very simple basic component as an example). If the diameter is too large and exceeds the allowable range of the difference, it will lead to a situation where it cannot be inserted. If the specific diameter is Very small, exceeding the lower limit of the allowable negative number of the difference, it will cause the problem of being loose and unstable. This kind of products are all unqualified, or the length of the cylinder is too long or too short, which exceeds the allowable range of the difference, and all products that are not acceptable, need to be abolished or reprocessed, which will inevitably lead to cost promote.
　　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 specific dimensions processed are undoubtedly not easy to be exactly the same as the basic theoretical dimensions of the drawings. The machining dimensions are all standard parts within the allowable range of the difference. Therefore, the requirement for precision parts machining is to process strictly in accordance with the basic theoretical dimensions. The second is excellent precision parts processing machinery and equipment and testing instruments. Excellent production equipment makes it easier to process precision parts, with higher precision and stronger actual effects. The testing equipment can detect the parts that do not meet the requirements, so that all the products sent to customers can truly meet the requirements.
　　 The above explained is the size requirements for precision parts processing. I hope it will be helpful to you after reading it. If you want to know more about precision parts processing, please contact us and we will be happy to help you Provide quality service!
