Stainless welded steel pipe in the same size specifications, the smaller the size of the tolerance, the higher the accuracy of processing. Therefore, in order to ensure the cutting effect of stainless welded steel pipe, the actual size should be controlled within the allowable range, that is, to design a reasonable size tolerance.
In the stainless welded steel pipe cutting process, some operators do not achieve the desired cutting effect, but can not find the specific reasons, spring that, it may be because there is no consideration of stainless steel pipe cutting dimensional tolerances. In the actual processing, due to processing and other factors, after cutting the actual situation and expected there may be some error.
Stainless stainless steel pipe in the cutting before the first to analyze the hardness, thickness, (nor exclude the analysis of the ductility test), and then the machine cutting accuracy, stability and saw blade flatness, stability and other comprehensive assessment, and then through the test method , The finished product size sample data, and its CPK calculation, and ultimately get the production capacity index, and finally to a reasonable size tolerance design. This process is relatively complex, because it is a more reliable way to ensure product quality.
