Abstract (en)
An outer blade cutting wheel includes an annular thin disc base (1) and a blade section (2) of bonded abrasive grains formed on the periphery of the base. The blade section includes widthwise side portions each of which is provided with channels (21) extending from an inner perimeter to an outer perimeter of the blade section. The cutting wheel is made by an electroplating method in which jig segments (51) applied to the base disc have flanges (51a) which define a cavity (c) for the abrasive grains and bond metal and also have protrusions (511) for forming the channels.
