  • Bossed disc-like member manufacturing method and bossed disc-like member manufacturing apparatus
    Patent number: 8875555
    Abstract: A bossed disc-like member manufacturing method and apparatus with which it is possible to simply form a boss portion with a desired height. The method includes a level difference formation step that moves a second portion, which is positioned on the inner peripheral side of a first portion in a radial direction of a disc-like blank, relative to the first portion in a first direction which is the thickness direction of the blank, thus forming a level difference between the first portion and the second portion. A conical portion formation step moves the second portion relative to the first portion in a second direction opposite to the first direction, eliminating the level difference. In this manner, a conical portion is formed in the second direction on the inner side of the second portion; and a burring step performs a burring process on the conical portion, thus forming the boss portion.
