  • Patent number: 6624376
    Abstract: A wire guide for an electric discharge machine is designed with three elongated, cylindrical ceramic rods which close around the electrode wire to maintain its center orientation. The ceramic rods are removably held in pivotal clamps for replacement when they become worn. The clamps are inter-linked to move toward and away from one another, with an infinite range of adjustment; and once the rods are positioned to clamp the wire electrode, the jaws are locked in position during the operation of the electric discharge machine.
