Abstract:
1. An outer blade cutting wheel comprising a base in the form of an annular thin disc of cemented carbide having an outer diameter of 80 to 200 mm defining an outer periphery, an inner diameter of 30 to 80 mm defining a bore, and a thickness of 0.1 to 1.0 mm, and a blade section disposed on the outer periphery of the base and comprising abrasive grains bound with a metal bond, the abrasive grains comprising diamond grains, CBN grains or a mixture of diamond grains and CBN grains, the metal bond having a Young's modulus of 0.7×10 11 to 4.0×10 11 Pa, said blade section having a thickness which is greater than the thickness of said base by at least 0.01 mm, wherein said metal bond consists of at least one metal selected from the group consisting of Fe and Co, an alloy-consisting of two of the foregoing metals, or an alloy consisting of at least one of the foregoing metals and phosphorus, and said blade section is formed by electroplating the metal bond so that the metal bond is deposited on the outer periphery of the base while binding the abrasive grains therewith.
