Claim Text:
1. A method for manufacturing a cutting/polishing tool including at least one cutting/polishing body, the method comprising: preparing a tool body; and forming a cladding layer including cutting material particles by spraying, onto an outer surface of the tool body, the cutting material particles and a metal powder, the metal powder having a specific gravity greater than a specific gravity of the cutting material particles, while heating the outer surface of the tool body using a heating device installed at a lower side of the outer surface of the tool body such that the direction of the energy emitted from the heating device is opposite the direction of gravity, so that the metal powder is deposited on the outer surface of the cladding layer and the cutting material particles are distributed in the cladding layer, wherein the outer surface of the tool body is divided into a plurality of cladding layer-forming sections of the tool body each corresponding to a part of the outer surface onto which the deposition of the metal powder forms a cladding layer section that is processed by the heating device in accordance with movement of the tool body relative to the heating device, wherein an acute angle defined between (a) a first vector that is a surface normal line extending outwardly from a deposition point of the outer surface of the tool body at which deposition is occurring, and (b) a second vector representing the force of gravity extending outwardly from the tool body in the downward gravity direction from the deposition point, is in the range of −10 degrees to 40 degrees, and wherein the cladding layer configures the at least one cutting/polishing body.
