Diamond tool

Abstract

Abstract PURPOSE:To enable excellent and high-precise finish machining of surface coarseness through one process, and to prevent choking of a tool, by a method wherein a flat ridge line is formed in a way each of the grinding grain projected parts of the straight part of a tool body is cut on a concentric circle. CONSTITUTION:Grinding grains 3a and 3b are electrodeposited on a straight part 1a and a taper part 1b of the body of 8 diamond tool for hole finish. By means of the grinding grains 3b of the taper part 1b, a prepared hole is ground. In this case, A projected part 30 of each grinding grain 3a of the straight part 1a is cut on a concentric circle, its outer periphery forms a flat surface 31, and a number of negative straight line blades are formed by ridge lines 32. Since a number of the grinding grains 3a are arranged at random to the straight part 1b, a ground surface rough-machined by the taper part 1b is finish-ground uniformly and in a planelike manner.
