  • Large-width, angular-sided segmental superabrasive grinding wheel
    Patent number: 6705936
    Abstract: The present invention relates to an abrading tool having a rotatable body of revolution having an axis of rotation. A peripheral workface is fixedly attached to the body of revolution. The workface is formed by a plurality of discrete, geometrically-shaped segments disposed in a contiguous relationship. Lines-of-juncture are formed by opposed edges of adjacent segments, whereby any diametrical plane, having at least one coplanar line-of-juncture, has a discontinuous coplanar curve, at least a portion thereof being the at least one coplanar line-of juncture, and whereby any longitudinal plane, having at least two coplanar lines-of-juncture, has opposed ends of the at least two coplanar lines-of-juncture being spaced apart.
