Stainless steel welded pipe in the same size specifications, the smaller the dimensional tolerance, processing, the higher the dimensional accuracy. Therefore, in order to ensure the cutting effect of stainless steel pipe, the actual size should be controlled to allow changes in the range, that is, design a reasonable amount of dimensional tolerance.
In the stainless steel pipe cutting process, some operators always reach the expected cutting effect, but can not find the specific reasons, spring that it may be because it does not take into account the size of stainless steel pipe cutting tolerance. In the actual processing, due to processing measurement and other factors, the actual situation after cutting and expected there may be some error.
Stainless steel pipe in the cutting before the first analysis of its hardness, thickness, (does not rule out the ductility of the analysis and testing), and then machine cutting accuracy, stability and blade flatness, stability and other comprehensive assessment, and then through the test method , To obtain the finished size sample data, and its CPK calculation, the final production capacity index, and finally a reasonable size tolerance design. This process, relatively speaking, is a little more complicated, because it is to ensure product quality more reliable approach.
