ABSTRACT:
A vibrating cutting tool having an input shaft driven by a live spindle of a machine tool and an output shaft having a cutter mounting portion. The input shaft and the output shaft are coupled together through a coupling mechanism so as to be at least circumferentially movable relative to each other. Recesses are formed in one of the input shaft and the output shaft and holes are formed in the other at locations opposite to the recesses. Moving elements are mounted between the recesses and the holes with a predetermined gap defined between the moving elements and the recesses or the peripheral surfaces of the holes. The gaps serve to restrict a circumferential movement of the moving elements. Springs are provided to urge the moving elements against the recesses. The movement of the moving elements is restricted by stoppers. An adjusting ring may be provided to adjust the biasing force of the springs.
