Kind Code:
A1
Abstract:
The electro-deposited diamond dresser is provided with: a disk-shaped wheel (2) which has tapered surfaces (21) on both sides of an outer circumferential portion thereof so as to decrease in thickness toward an outer circumferential surface; a diamond grinding stone layer (3) extending toward outer circumferential edge portions of the tapered surfaces, and having a plurality of small particle-sized diamond grinding stones plated thereon as a plated layer; a plurality of installation grooves (5) formed in the outer circumferential surface of the wheel and having two intra-groove wall surfaces which form a predetermined angle; and polygonal single-crystal diamond grinding stones (4) which have a particle size greater than the small particle-sized diamond grinding stones, and have installation crystal faces (M1, M2) forming an angle equal to the predetermined angle, wherein, when the installation crystal faces are installed on the two intra-groove surfaces (51a, 51b), the surface parallel to the outer circumferential surface of the wheel is not a cleavage surface. In each of the polygonal single-crystal diamond grinding stones, the installation crystal faces are plated as plated layers (32) on the two intra-groove wall surfaces of the installation grooves of the wheel.
