Zusammenfassung:PURPOSE:To improve both machining speed and finishing surface roughness as well as to prevent a workpiece from being rusted, by applying a mixture of polyvinyl alcohol and sodium carboxymethylcellulose to the surface of an electrode wire. CONSTITUTION:Benzenesulfonylaminoalkylcarboxylic acid, triethanolamine and polyvinyl alcohol are mixed in the ratio of 10:10:2 and moreover mixed with water so as to cause the visicosity to become 10-100cp or so. A copper wire of about 0.2mm., etc., is passed through the inside of this mixed aqueous solution and, after a mixture of the said chemicals is applied to its surface, solidified by means of hot air drying. The thickness of this chemical mixture's membrane comes to 1-10mum or so, using an electrode wire for wire-cut electro-discharge machining being obtained like this, and water is used as a machining solution.
