  • Publication number: 20190126706
    Abstract: A method of manufacturing a suspension coil spring includes forming first shot peening indentations on a surface of a wire by projecting first shots toward the wire and forming a compressive residual stress portion to which a compressive residual stress is imparted from the surface of the wire to a first depth, and projecting ball shots as second shots toward a lower end turn portion by an ultrasonic apparatus. A size of each ball shot is larger than a size of each first shot. The method includes forming second shot peening indentations on a surface of the lower end turn portion, and a deep residual stress portion in the lower end turn portion, a compressive residual stress of the deep residual stress portion imparted from the surface of the wire to a second depth that is deeper than the first depth.
