METHOD OF MANUFACTURING SAW WIRE

PROBLEM TO BE SOLVED: To provide a manufacturing method for fixing a large number of abrasive grains uniformly and firmly on the whole periphery of a long core in a method of manufacturing an abrasive grain fixed type saw wire by a plating method. SOLUTION: The large number of abrasive grains are fixed to the metal core by compound Ni plating, and current density in a compound Ni plating tank 13 is set to limit current density or more. Surface unevenness thereby appears due to this unusual plating simultaneously with producing many hydrogen bubbles, and the abrasive grains are trapped by the unevenness and hydrogen bubbles to fix the abrasive grains uniformly and firmly in the circumferential direction of the core.
