Abstract: A method for making an 8-shaped hole in a bimetallic sleeve, including the steps of preparing two bimetallic tubes, each tube having substantially the same dimension; and also preparing a rear sleeve part, and a front sleeve part; fixing each tube with a plurality of clamping blocks having openings on one side; moving each clamped bimetal tube to a thread cut machine, adjusting the spindle of the thread cut machine to move parallel to the openings on one side of the clamping blocks, and then cutting the clamped tube to form a tube of C-shaped cross section; detaching said tube of C-shaped cross section from said plurality of clamping blocks, and clamping two of said tube of C-shaped cross section together with two fixtures having an 8-shaped cross section; applying spot welding at joints of said two tubes of C-shaped cross section for 6-8 spots to form an 8-shaped hole bushing, and then detaching said two fixtures of 8-shaped cross section; heating the rear sleeve part in a heating furnace for 3-5 hours to re
