Abstract

The method involves cutting a cylindrical stock bar of high carbon steel into set lengths (1) to be machined. Each piece is then treated to confer a ductility not exceeding HRB 75 Rockwell. Each piece is placed into a first punch matrix (3) and pressed with a punch (4) to a pressure not less than 17 tonnes per square centimetre. This is followed by a forming stage which involves placing the work in a second matrix and pressing it with w perforating punch to form a bore (10) . The bore punch has different diameters to form steps on the bore. A punch stage involves placing the work in a third matrix to form the end of the bore. Teeth are then precision machined by press forming the work in a pinch with an air vent.
