Abstract

A wire guide consisting of a V-groove-type guide, a device for supplying machining liquid, and a die-type wire guide removably attached at the lower surface of the V-groove-type guide causes increased machining accuracy while used in both non-taper machining and taper machining modes. The increased accuracy is achieved after the wire passes through the V-groove-type guide by using the die-type wire guide to return the wire to a straight path to improve the linearity of the wire and, accordingly, improve machining accuracy.
