This time, please allow me to tweet about the processing PR of Miyawaki Steel Pipe from a quality control perspective. In the previous blog, I mentioned the NC long-length processing machine, and I received a report from the site where they were processing slits in square pipes, saying, "The pipe is deformed, what should we do?" When I headed to the site... They said, "We left a bridge (point) to prevent deformation during processing, but it still deformed." Even in processing that does not use plasma or gas, square pipes that are roll-formed often deform inward when slit processing is performed. *You can view the detailed content of the blog through the related links.
