Abstract:
1. An electrode tip dressing apparatus, in which top of an electrode tip is pressed against pluralities of dressing tools radially arranged; the dressing tools are rotated around the electrode tip so as to conduct a relative displacement between the top of the electrode tip and a dressing portion of each of the dressing tools; and the top of the electrode tip is plastically deformed into a given form, wherein the dressing portion of each of the dressing tools has a surface that curves around a longitudinal axis of the dressing portion, the surface being defined by a plurality of curvature radii differing from one another along a length of the dressing portion, and wherein the dressing portion of each of the dressing tools is constructed so that an amount of dressing work, in which the dressing tools conduct to the top of the electrode tip, becomes constant from the rotational center of the dressing tools to the outer side of the dressing tools.
