Abstract:
1. A tee forming and trimming system comprising: a milling head milling a hole in a surface; a forming die forming a rough pullout joint when pulled from an inside region of said surface through said hole; a drawbar for pulling said forming die through said hole; a hydraulic cylinder for driving said drawbar; a universal driver; said universal driver being located distal of said forming die relative to said drawbar; said drawbar attaching to said universal driver when said drawbar is extended into said hole and through said forming die, wherein said forming die is pulled up through said hole when said hydraulic cylinder drives said drawbar away from said tube; a face trim head trimming said rough pullout joint into a finished pullout joint; wherein said face trim head is automatically exchanged with said milling head, thereby completing a milling operation and a face trimming operation at the same location of said tube tee forming and trimming system; and a loading/moving system automatically moving said surface from a position where said milling head makes said hole to a position where said forming die makes said pullout joint to a position where said face trim head trims said rough pullout joint into said finished pullout joint.
