A micro EDM servo-head is disclosed which includes a servo, a lead screw, a carriage block engaging the lead screw, a support block, a contact block secured to the carriage block, and an electrode guide system coupled to the support block for controlling the position of the electrode of an EDM apparatus to which the micro EDM servo head is attached. The electrode guide system includes an electrode guide bottom having a longitudinal groove, and a floating guide cover which is biased toward the electrode guide bottom such that the electrode is forced into the groove and the position is controlled by forcing the electrode into the groove.
