<p>PROBLEM TO BE SOLVED: To provide an economically advantageous ultrasonic vibratory cutter with its cutter replaceable. SOLUTION: A cutter 2, which has cutting blades on the periphery of a disc, e.g. a dicing blade, a diamond blade, and a saw blade, is externally fitted in a male screw part 1c of a resonator 1. By fastening a nut 3 to the male screw part 1c, the cutter 2 is mounted so as to be located at the point of minimum amplitude by vibration of the resonator 1. By rotating the nut 3 in the direction in which the nut 3 loosens, the cutter 2 can easily be removed from the cutter 2 for replacement.</p> |
