PROBLEM TO BE SOLVED: To provide a compactible electrode tip shaping device in which high shaping precision can be secured. SOLUTION: Each electrode tip shaping tool shaping an electrode tip is stored into the hollow part 10 of the rotating shaft 9 of a hollow shaft servomotor 8. Thus, a speed reduction mechanism is abolished, and the compacting of the device is made possible. Further, since the servomotor 8 (hollow shaft servomotor) is adopted as a power source rotating the electrode tip shaping tool, the rotating speed of the electrode tip shaping tool (rotating shaft 9) can properly be set in accordance with the electrode tip, and the shaping precision of the electrode tip can be secured.
