PROBLEM TO BE SOLVED: To easily manufacture a wire saw at a high speed by bonding a synthetic resin and abrasive grains to a wire core material with the electrodepositon method, and heating and treating them so as to fix the abrasive grains with the synthetic resin. SOLUTION: A wire core material 1 is driven for traveling by rotating pulleys 2, 3. An electrodepositon tank 4 filled with the water base paint including the mixture of the synthetic resin and the abrasive grains, and the synthetic resin and the abrasive grains are adhered to the wire core material 1 in electrodepositon tank 4. The wire core material 1, to which the synthetic resin and the abrasive grains are adhered in the electrodepositon tank 4, is fed to a first washing vessel 5, a second washing vessel 6 and a third washing vessel 7 in order, and a surface thereof is washed. The washed wire core material 1 is fed to a heating furnace 8, and heated and treated so as to dry the water base paint, and the synthetic resin is hardened and strongly secured the abrasive grains, and the surface of the wire core material 1 is formed with an abrasive grain layer so as to form a wire saw. |
