<p>A wire or rod drawing apparatus (11) has a drawing die (18) and a metallic tubular member (17) through which the wire (12) passes before entering the die. A D.C. voltage is applied between the rod and the tubular member for creating a voltage difference therebetween, and a lubricant (23) is applied to the wire within the tubular member to function as an electrolyte.</p> |
