<P>PROBLEM TO BE SOLVED: To provide a cutter for tip dressing capable of reliably cutting the center section of, in particular, an electrode tip. <P>SOLUTION: One end of four tip-receiving parts 7 is integrally connected to each other at the rotation center 10a of a rotating body 10, and the other end thereof is separated from each other in the rotational direction X of the rotating body 10. Further, two tip-receiving parts 7 are arranged oppositely to each other on both sides of the rotation center 10a of the rotating body 10, and the center of a fore end 2a of an electrode tip 2 corresponds to a connection part on one end side. A cutting blade part 8 is provided to one of the tip-receiving parts 7 opposite to each other, and extends to the other tip-receiving part 7 side over the rotation center 10a of the rotating body 10 while being tilted so as to be gradually separated from an electrode tip fore end 2a. <P>COPYRIGHT: (C)2013,JPO&INPIT |
