Abstract
A grindstone that enables grinding, polishing, super-finish polishing by using the same grindstone, without clogging even if the grindstone is being used continuously, in which a grinding/polishing section for processing a workpiece has a honeycomb structure formed by arranging polygonal prisms with no clearance therebetween. The grindstone includes the grindstone columns consisting of abrasive grains and binder and having an axis in depth direction of grinding/polishing surface, which are disposed on intersections or wall portions of the honeycomb structure. Porous elastomer is disposed inside the honeycomb structure, thus making it possible to perform a super-finish polishing.
