Abstract
(EN) A first piece (13) includes a first ring portion (13b) and a second ring portion (13c) arranged in an axial direction. An inner diameter and an outer diameter of the first ring portion (13b) are larger than an inner diameter and an outer diameter of the second ring portion (13c), respectively. In a state in which the first piece (13) is disposed between a first set and a second set, the first piece (13) is processed, and a second piece (16) is acquired.
(FR) L'invention concerne une première pièce (13) comprenant une première partie annulaire (13b) et une deuxième partie annulaire (13c) agencées dans une direction axiale. Un diamètre interne et un diamètre externe de la première partie annulaire (13b) sont respectivement plus grands qu'un diamètre interne et qu'un diamètre externe de la deuxième partie annulaire (13c). Dans un état dans lequel la première pièce (13) est disposée entre un premier ensemble et un deuxième ensemble, la première pièce (13) est traitée et une deuxième pièce (16) est acquise.
(JA) 第1ピース(13)は、軸方向に並んで配される第1リング部(13b)と第2リング部(13c)とを含み、第1リング部(13b)の内径及び外径は第2リング部(13c)の内径及び外径に比べてそれぞれ大きい。第1セットと第2セットとの間に第1ピース(13)を配置した状態で、第1ピース(13)を加工して第2ピース(16)を得る。
