FIXED ABRASIVE GRAIN WIRE, AND METHOD FOR PRODUCTION THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a fixed abrasive grain wire favorable in cutting sharpness from the initial stage of cutting process and excellent in processing efficiency and processing accuracy.SOLUTION: A fixed abrasive grain wire 10 is provided with: a metallic wire 11 having ductility; diamond abrasive grains 14 which are one type of super-abrasives made by temporarily fixing a part of a conductive covering layer 12 formed on a part of a surface to the outer peripheral surface of the wire 11 in a closely contacting state by a first electrodeposition layer 13; and a second electrodeposition layer 15 covering the electrodeposition layer 13 on the outer peripheral surface of the wire 11 and the covering layer 12 of the diamond abrasive grains 14 in order to fix the diamond abrasive grains 14 to the outer peripheral surface of the wire 11. The covering layer 12 is composed of Ni, and the first and second electrodeposition layers 13 and 15 are each formed by nickel plating.
