Abstract
A roundness processing device for a slipper surface of a rocker arm capable of rounding the slipper surface of the rocker arm without forming roundness on the polishing surface of a grinding wheel. A wheel side unit containing a disc-shaped grinding wheel, a jig side unit for holding and oscillating the rocker arm, a conveyor for conveying the rocker arm, and an access robot for moving in and out the rocker arm are automatically driven and controlled, as being mutually related, by automatic control such as numerical control. The polishing surface of the grinding wheel is formed on a plane vertical to the rotary shaft line of the grinding wheel, while the slipper surface of the rocker arm is oscillated about the oscillation shaft line positioned at a distance of a specific radius of curvature from the polishing surface. This oscillation shaft line is parallel to the polishing surface, and within a plane perpendicular to the polishing surface containing the contact line between the polishing surface and slipper surface.
