Apparatus for the electrical discharge machining of a circumferential section from the wall of a bore in a metallic cylinder has a housing and a wire electrode guide disposed within the housing. A wire feeder continuously feeds a wire electrode to the wire electrode guide. The wire electrode guide also moves the wire electrode radially into and out of an axial groove extending between the circumferential grooves in the bore wall. The wire electrode guide further moves a wire electrode, when the wire electrode is disposed within the axial groove in the bore wall, between a first position in which the distance along the bore wall between the point where the wire electrode enters and leaves the axial groove is the same as the distance between the circumferential grooves, and a second position in which the distance along the wall of the bore between the point where the wire electrode enters and leaves the axial groove is greater than the distance between the circumferential grooves. A rectifier and current controller provide an electrical discharge through the wire electrode. A motor resolver rotates the wire electrode guide circumferentially within the bore.
