ABSTRACT:
Method and apparatus for electrochemically deburring a diesel injector nozzle workpiece having a gallery cavity and having a first fuel hole and an air hole intersecting the gallery cavity at a first location. A first electrode is inserted into the first fuel hole such that the electrode tip is near the first location. A post is inserted in the air hole into the gallery cavity. An electrolyte flow is directed through a first channel of the post to the gallery cavity and through a second channel of the post from the gallery cavity. A voltage potential is applied between the first electrode and the workpiece to remove burrs previously formed at the first location.
