Filed: 1987-07-23
Abstract: PURPOSE:To enable execution of excellent work in cutting male screw and to increase service life of a tool, by a method wherein a film of a rigid metallic compound, in which the thickness of a film is increased toward the chamfer angle is axially formed on the surface of a female screw, and back taper is formed on a parallel screw part. CONSTITUTION:A film 24 of titanium nitride being a rigid metallic compound is formed on the surface of a female screw 12, and the thickness of a film is decreased from a surface 14 toward a back 26. A film in the vicinity of the surface 14 is approximate 5mum, and the thickness of the film in the vicinity of the back 26 is approximate 1mum. The diameter of a parallel screw part 18 available before the film 24 is formed is approximately specified, and by formation of the film 24, a back taper in which a diameter is increased from the chamfer angle 16 side toward the back 26 is formed on the parallel screw part 18.
