摘要： A method and apparatus for grinding a split piston ring having at least one inwardly converging top or bottom wall member by bringing such wall into engagement with a rotating grinding member having a spherical segment working surface, the path of such relative movement being along a line which is coincident with the axis of the piston ring and also coincident with a radius of the spherical surface of the grinding member, whereby all of the inwardly converging surface of the split piston ring is concurrently ground to conform to the curvature of the spherical segment surface of the grinding member.
