CUTTING SEGMENT WHEEL AND METHOD OF MANUFACTURING SAME Russian patent published in 1997 - IPC

FIELD: mechanical engineering. SUBSTANCE: cutting wheel provided with radial slots between segment has housing made up a metallic disk over periphery of which diamond segments are secured to shaped segment projections. The segment projections, which form radial slots between segments, are provided with additional dovetail projections of less length. The end face surfaces of the projections are provided with concentric grooves, that are arranged on both sides and shifted with respect to each other, and shaped dovetail grooves. The method of manufacturing the cutting diamond segment wheel comprises forming a solid ring diamond layer on a housing blank by cold pressed fitting and caking and then cutting out radial slots between segments in the diamond layer and housing until they enter the end face openings interposed between the projections to form the diamond segments. The housing blank is made up as a disk provided with trapezium grooves and through end face openings positioned at sites where the radial slots pass. EFFECT: enhanced reliability. 2 cl, 3 dwg
