Title:
METHOD AND DEVICE FOR MANUFACTURING SAW WIRE
Document Type and Number:
WIPO Patent Application WO/2012/124547
Kind Code:
A1
Abstract:
[Problem] Provided are a method and a device for manufacturing a fixed abrasive grain saw wire, the method and the device being configured so that, even if a highly efficient wire delivery method in which the density of abrasive grains is high and the wire is reciprocated is used, a variation in the amount of the abrasive grains adhering to the outer surface of the wire is prevented to make the distribution of the adhesion of the abrasive grains uniform.
[Solution] The present invention is provided with: a coating tank (16A) in which a coating liquid (M1) containing abrasive grains (D) is retained; a wire delivery means (2) for causing a wire (W) to pass through the coating liquid (M1); an electric current supply means (3) for supplying an electric current to the wire (W) and the coating liquid (M1); an abrasive grain amount calculation means (4) for calculating the amount of the abrasive grains (D) adhering to the outer surface of the wire (W) having been passed through the coating liquid (M1); and an electric current value control means (5) for performing control so that a variation in the amount of the abrasive grains adhering to the outer surface of the wire (W) is within a predetermined range, the control by the electric current value control means (5) being performed by increasing and decreasing, on the basis of the calculated amount of the abrasive grains, the value of the electric current which is caused to flow through the wire (W) within the coating liquid (M1) by the electric current supply means (3).
