Abstract
A pair of guide devices 5, 6 for the wire electrode 1 in a discharge machining apparatus are disposed just above and below a workpiece 3. Each device includes three or more equally circumferentially spaced guide rings 8, 9, 10 surrounding the electrode and biased outwardly by tension springs 11, 12, 13 coupled to an enclosing frame member 7,to thereby center the electrode and prevent any lateral displacements during use. As an alternative the rings may be replaced by guide balls, 22, 23, 24 biased radially inwardly against the electrode by compression springs or fluid cylinders.
