Under what conditions can high-precision parts be processed?

         The process flow of high-precision parts processing has extremely strict regulations. A little carelessness during processing will cause the deviation of the product workpiece to exceed the dimensional tolerance range. It must be processed again, or the blank is declared damaged, which greatly increases the cost of manufacturing. Therefore, today I will talk about the regulations for high-precision parts processing, which can help everyone improve productivity.
         First of all, there are regulations at the specification level. We must strictly follow the dimensional tolerance regulations of engineering drawings for processing. Although the parts processed and manufactured by the company are not easy to be exactly the same as the dimensions of the drawings, the specific size tolerance range of the basic theoretical specifications , all belong to qualified products and are parts that can be used.

         The distribution of the processing sequence of high-precision CNC parts is based on the structural roughness of the parts and the need for precise positioning and clamping. The key is that the rigid needs of the product workpiece are not destroyed. The processing of the upper process should not endanger the market positioning and blessing of the lower process, and the processing process of universal high-precision parts in the middle also needs to be fully considered.

         Carry out the inner wall processing process, and then carry out the appearance design processing process. With the same precise positioning, the support method or the process of the multi-pass tool processing carried out in the same installation, it is better to be carried out in conjunction to reduce the frequency of repeated precise positioning, the frequency of tool change and the frequency of moving pins, and the multi-pass processing carried out in the same installation. The technological process should be assigned a technological process with little damage to the rigidity of the product workpiece.
