ABSTRACT:
In order to prevent an electrode tip 8 from being burred during dressing process, thereby attaining high quality and stability of the electrode tip, a tip dresser features a screw-threaded circumference 5 formed around the rotatable cutter holder 1 for securing a one- or two-piece formed cutter element 2, for permitting the holder 1 to be rotated in one direction A manually or by a suitable driver. Frusto-conical recesses are symmetrically formed in both sides of the holder 1 for receiving the electrode tips, allowing the cutter element 2 to be mounted so as to slightly extend by a predetermined amount beyond the conically recessed surface. Another feature is in the form of apertures 6 and 7 provided through the holder 1 for discharging the cutting chips: one aperture 6 formed on the forward front side of the rotating direction of one machining edge 2a for the bevel surface of electrode tip 8, and another one 7 on the forward front side of rotating direction of another machining edge 2b for the end surface machining. The aperture 6 is formed along the edge 2a, and aperture 7 is formed so as to reach at least the boundary between the bottom and the conical side surface of each of the frusto-conical recesses.
