A machining position correcting device is applied to an electrochemical machining device that makes an electrolyte flow out of a distal end part of an electrode bar extending along an axis while rotating the electrode bar about the axis to electrochemically machine a material to be machined in a region from the distal end part of the electrode bar. The machining position correcting device includes a position detector configured to detect a rotational position of a feature point provided to the electrode bar.

A small-hole electric discharge machine (100) applying voltage between a small-hole machining-use electrode (116) attached to a spindle (112) and a workpiece (130) attached to a table (118) to drill a small hole in a workpiece by electric discharge energy, the small-hole electric discharge machine including an electrode guide (10) having a hollow part through which the electrode is passed and guiding the electrode at the front end of the hollow part in a parallel state with respect to an axis (Rz) of the spindle while shifted by a predetermined distance (S) from the axis and a W-axis chuck (144) holding an electrode guide to be able to measure and maintain a position of a front end of the electrode guide in direction of the axis of the spindle and an angular position about the axis.

The present application provides an electrical discharge machining system for drilling a hole in a workpiece using a flushing fluid. The electrical discharge machining system may include an electrode with the electrode positioned in an electrode guide, and an integrated external flushing system. The integrated external flushing system may include a guide cap and a concentric flushing channel defined between the guide cap and the electrode guide so as to allow the flushing fluid to remain attached to the electrode guide.
