METHOD OF MANUFACTURING THE DIAMOND TOOL Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: during the batch pressing the girdle and the bushing are pressed against the face surfaces of the foundation protrusions. The batch placement is carried out through a charging hopper with the cross-section area of the outlet hole smaller or divisible by the area of the face surface of the sectors. Before pressing out the girdle and the bushing are extracted from the press-mold. During the diamond placement between them the graphite grains are glued on the press-mold foundation.
