Abstract:
An abrasive grinding wheel that can be rotated about an axis of rotation, the abrasive grinding wheel comprising:a means for defining an axis of rotation of the abrasive grinding wheel; a substantially cylindrical region of abrasive material having a circumferentially extending abrasive surface at a peripheral band thereof and formed from a plurality of layers of abrasive particles, each layer of abrasive particles separated from an adjacent layer of abrasive particles by a layer of bond material, and each layer of abrasive particles extending along at least a portion of the circumference of the abrasive surface and in a radial direction of the substantially cylindrical region of abrasive material from the abrasive surface toward the axis of rotation; and wherein any circular path defined by an intersection of a plane perpendicular to the axis of rotation of the abrasive grinding wheel and a complete circumference of the abrasive surface will intersect at least one of the plurality of layers of abrasive particles.
