In a method and device for processing the curved bearing surface (2a) of a rocker arm (2) without imparting curvature to the polishing surface of a grinding wheel, the polishing surface (1a) of a grinding wheel disc (1) is formed on a plane perpendicular to the rotational axial line of the grinding wheel (1), while the bearing surface (2a) of the rocker arm (2) which is polished by being pressed against this polishing surface (1a) is oscillated about the axis of a shaft (24) positioned at a distance of a specified curvature from said polishing surface (1a). The axis of the shaft 24 is parallel to said polishing surface (1a), and is present within the plane including the contact line of said polishing surface and bearing surface (2a). …<IMAGE>… |
