Description
図1は、本発明に係る車輪用軸受装置の一実施形態を示す縦断面図、図2は、図1の外方部材の研削工程を示す説明図、図3は、図2の変形例を示す説明図である。
まず、(a)に示すように、アウター側の端面Faをマグネットチャック20aに当接させ、ナックル(図示せず)の嵌合面となるインナー側の外周面21をシュー22によって支持した状態でこの外周面21とインナー側の端面Fbが研削砥石23によって同時研削され。所定の精度に規制されている。ここで、研削砥石23は、インナー側の外周面21を研削する外周砥石23aと、端面Fbを研削する端面砥石23bが一体形成された総型砥石からなる。これにより、加工工数が複雑になることなく効率良く研削加工ができ、加工コストの高騰を抑制することができる。
