Abstract
The super finishing stone has such a shape that a width of an abrasive surface in a direction perpendicular to a radial direction becomes gradually narrower from outside to inside in the radial direction, when the raceway surface and the abrasive surface in contact with the raceway surface are seen at a plurality of sections perpendicular to the radial direction of the object to be worked, so that the abrasive surface and the raceway surface in contact with the raceway surface may intersect with each other at a constant angle at opposite side edges of the abrasive surface.
