Abstract

See full text

An outer blade cutting wheel is provided comprising an annular thin disc base and a blade section of bonded abrasive grains on the periphery of the base. Provided that an imaginary range is delineated by two imaginary planes extending parallel to the planar surfaces of the base and tangent to widthwise side portions of the blade section and two imaginary circumferences defined about the rotational axis and extending tangent to inner and outer perimeters of the blade section, the blade section occupies 10-40% by volume of the imaginary range minus the region of the base, and the widthwise side portions of the blade section have a dented shape relative to the imaginary planes. The cutting wheel is capable of cutoff machining at a high feed speed while maintaining a high accuracy and a low cutting load.
