Abstract
An outer blade cutting wheel comprising an annular thin disc base of cemented carbide and a blade section is manufactured by disposing permanent magnet pieces on the side surfaces and inward of the outer periphery of the base to produce a magnetic field, providing magnetic coated diamond and/or CBN abrasive grains such that the magnetic field may act on the grains, causing the grains to be magnetically attracted to the base outer periphery, and electroplating or electroless plating whereby the abrasive grains are bound to the base outer periphery to form the blade section.
