Patent ID: 7044990

Claim:
A method of manufacturing a vitrified bond tool including (i) a support body, (ii) a vitrified bond layer which is formed on a working surface of said support body, and (iii) a plurality of abrasive grains which are held by said vitrified bond layer so as to be fixed relative to said working surface of said support body and which are spaced apart from each other with spacing between the adjacent ones of said abrasive grains, wherein said abrasive grains are arranged in a lattice, at a predetermined pitch between adjacent ones of said abrasive grains, said method comprising: forming a backing layer, as a precursor of said vitrified bond layer, on said working surface of said support body, said backing layer including a vitrified bond; forming a pattern layer, as a precursor of said vitrified bond layer, in a predetermined pattern on said backing layer, said pattern layer including a vitrified bond; sprinkling said abrasive grains over said pattern layer before said pattern layer is dried; and firing said backing layer, said pattern layer and said abrasive grains which adhere to said pattern layer and are arranged in said predetermined pattern on said working surface of said support body.
