Abstract
A superabrasive wheel ( ) for mirror finishing includes an annular base plate ( ) having an annular end surface ( ) and a plurality of superabrasive members ( ), each having a peripheral end surface ( ), arranged along the periphery of the annular base plate ( ) at intervals from each other in a circumferential direction and fixed onto the end surface ( ) of the base plate ( ). Each of the superabrasive members ( ) has a flat plate shape, and is so arranged that the peripheral end surface ( ) is substantially parallel to the rotary shaft of the superabrasive wheel ( ). A surface ( ) defined by the thickness of the flat plate shape of each superabrasive member ( ) is fixed onto the end surface ( ) of the base plate ( ). In the superabrasive members ( ), superabrasive grains are bonded by a binder of a vitrified bond. In another superabrasive wheel ( ) for mirror finishing, each one of plural superabrasive members ( ) has an angularly bent V-shaped plate configuration or a curved C-shaped plate configuration, and is so arranged that a peripheral end surface ( ) thereof is substantially parallel to the rotary shaft of the superabrasive wheel ( ).
