    摘要: A method for forming a hub having blind bore is provided. The blind bore hub is formed integrally with a solid circular disc by displacing metal radially inward from the upper surface toward the center of the disc to form a hub, and then punching a bore opening through the center of the hub to provide a blind bore therein. A blind bore hub formed by the foregoing method is also provided.
