In the mechanical industry, the connection between a small diameter tube and a round tube is generally a welding method, and the intersection of the tube and the tube is a line of intersection. The quality of the intersecting line directly affects the quality of the weld. In the past, the processing method used in the past was to first blank the tube, and then use a semicircular file to manually cut out the intersecting line. This method is not only labor intensive, but also time consuming and has low production efficiency.
