摘要： An electroerosion boring method and apparatus for machining a small hole in a workpiece at high speed using a supplemental working fluid flushing means for directing working fluid toward a peripheral edge of the inlet-side opening of the hole being machined, and a working fluid supply means for supplying the working fluid to the jet nozzle means under pressure so that the working fluid at a pressure of at least 20 kg/cm.sup.2 or more is directed from the supplemental flushing means. The supplemental high pressure flushing effectively prevents the machined chips from adhering to the peripheral edge of said hole without interfering with high-speed machining performance.
