How to ensure the cutting effect of stainless steel welded pipe
Stainless steel welded pipes with the same specifications, the smaller the dimensional tolerance, the higher the dimensional accuracy of processing. Therefore, in order to ensure the cutting effect of the stainless steel welded pipe, the actual size should be controlled within the allowable range, which is to design a reasonable dimensional tolerance.
In the cutting process of stainless steel welded pipes, some operators always fail to achieve the expected cutting effect, but they cannot find a specific reason. Kasuga thinks that it may be because the dimensional tolerances of cutting stainless steel welded pipes are not considered. In actual processing, due to processing measurement and other factors, there may be some errors between the actual situation and the expectations after cutting.
Before cutting the stainless steel welded pipe, first analyze its hardness and thickness (not to exclude the analysis and testing of ductility), and then comprehensively evaluate the cutting accuracy, stability and flatness and stability of the saw blade, and then pass the test method , Get the finished product size sample data, and perform CPK calculation on it, finally get the production capacity index, and finally carry out reasonable size tolerance design. This --- process is relatively complicated, because it is a more reliable way to ensure product quality.
