In case of machining by the large-size machine tool, the vibration occurs easily as compared with machining by the medium and small-size one. This vibration deteriorates not only the quality of finished surface but also the sharpness of cutting edge, and furthermore the performance of machine tools. The impact damper needs some acceleration to effectively function and thus the low frequency vibration cannot be suppressed by the impact damper. In contrast, the dynamic damper needs some attached mass to effectively function, and thus it is generally difficult to apply to large-size machine tools. This paper describes the principle of a newly developed dynamic impact damper and simulated results of its motion in time domain. The paper also reveals that the dynamic inpact damper well facilitates the suppression of the low frequency vibration in large-size machine tools.
