<p>PROBLEM TO BE SOLVED: To provide a novel dynamic vibration absorber.SOLUTION: A dynamic vibration absorber 3 of this invention is disposed on a rotating tool, and is arranged in such a manner that a longitudinal direction of the dynamic vibration absorber 3 is in a circumferential direction of a rotating axis of the tool. A length of the dynamic vibration absorber 3 from an attachment position is preferably within a range of 0.01-6000 mm. A width of the dynamic vibration absorber 3 is preferably within a range of 0.008-5000 mm. A thickness of the dynamic vibration absorber 3 is preferably within a range of 0.01-500 mm. A ratio of the length to the width of the dynamic vibration absorber 3 is preferably within a range of 1.2-100. A total mass ratio is preferably within a range of 0.01-0.12. Further, a natural frequency ratio is preferably within a range of 0.5-1.0.</p> |
