New development of a grinding wheel with resin cured by ultraviolet light

The present paper proposes a unique method for developing a grinding wheel and polishing disk by piling and curing ultraviolet-cured resin mixed with an abrasive grain. The grinding characteristics of the resin-piled grinding wheel (RP wheel) were analyzed by a grinding test. The cured depth and width of the ultraviolet-cured resin increased with the duration of exposure to the ultraviolet light. A 5–l0 s exposure to ultraviolet light suffices to fabricate a small area of the grinding wheel surface. It is possible to manufacture polishing disks and grinding wheels that hold the abrasive grain tightly and distribute it uniformly. The RP wheel has a large capacity for grinding, due to its sufficient bending strength and elastic modulus.
