METHOD AND DEVICE FOR MANUFACTURING SAW WIRE

[Object]To provide a method and device for manufacturing an abrasive grain-fixed saw wire that realize homogeneous distribution of abrasive grains adhered to the outer surface of a wire while suppressing variations in the amount of abrasive grains adhered to the outer surface of the wire, even in a high-efficiency wire feeding mode with a high density of abrasive grains, back-and-forth running of the wire, and the like.[Constitution]The present invention includes: a plating tank A that stores a plating solution M containing abrasive grains D; a wire feeding means that lets a wire W pass through the plating solution M an electric current supply means that supplies an electric current to the wire W and the plating solution M an abrasive grain amount calculation means that calculates the amount of abrasive grains D adhered to the outer surface of the wire W having passed through the plating solution M and an electric current control means that increases or decreases the value of an electric current flown into the wire W in the plating solution M by the electric current supply means according to the calculated amount of abrasive grains to control variations in the amount of the abrasive grains adhered to the outer surface of the wire so as to fall within a predetermined range.
