ABSTRACT:
A superfinishing grindstone suitable for precision grinding, that contains either RB (rice bran) ceramic fine grains or CRB (carbonized rice bran) ceramic fine grains or a combination of both, for use as abrasive grains. The grains of RB ceramic fine grains and CRB ceramic fine grains have multiple small pores which allow the grains to be easily removed from a finished structure. These fine grains have a high Vickers hardness, which makes them highly resistant to bending, scratching, abrasion or cutting.
