Abstract

An electroplated wheel comprises a metal base formed to a disc shape and rotationally driven about a rotational axis and a superabrasive grain layer formed to have numerous superabrasive grains fixed by plating on a belt section that extends in a predetermined width on an outer peripheral portion of the metal base. In the electroplated wheel, a plurality of masking portions having no superabrasive grains electrodeposited thereat are formed of gel adhesive fixed as dots to be larger than the superabrasive grains by a dispenser at intersection points of a plurality of concentric array circles imaginarily drawn concentrically of the rotational axis to divide the belt section at equal intervals and a plurality of width-direction array lines imaginarily drawn from one end toward the other end of the belt section to divide the belt section at equal intervals in a circumferential direction.
