BASE BOARD FOR SUPERABRASIVE GRAIN CUTTER AND METHOD OF MANUFACTURE AND SUPERABRASIVE GRAIN CUTTER USING THIS BASE BOARD

摘要

PROBLEM TO BE SOLVED: To provide a base board for a superabrasive grain cutter having both toughness-lightness possessed by a steel raw material, and rigidity-abrasion resistance possessed by cemented carbide, its manufacturing method, and the superabrasive grain cutter using this base board.;SOLUTION: The cemented carbide 5 is laminated and arranged on both sides of the steel raw material 4, and is sintered and joined by a sintering method, more actually, a discharge plasma sintering method being a kind of pressurizing/current-carrying heating sintering method to manufacture the base board 1.;COPYRIGHT: (C)2002,JPO
