Beschreibung
Zusammenfassung:	An electrochemical machining system (10) comprises a component (18) having a passage (20), the passage (20) has an opening (45) and an internal surface (22) formed along the passage (20), a conductive wire (24) has insulation (26) covering portions of the conductive wire (24) forming gaps (27) having exposed wire (24); the conductive wire (24) is inserted in the passage (20); a power source (28) is coupled to the component (18) and the conductive wire (24) forms an electrical circuit (16), wherein the component (18) comprises an anode (14) and the conductive wire comprises a cathode (12); and an electrolyte (34) within the passage (20) contacting the internal surface (22) and the exposed wire (24), wherein the electrolyte (34) comprises a charge-carrying liquid configured to complete the electrical circuit (16) between the cathode (12) and anode (14).
