Abstract
A cutting tool includes a cutting insert mounted to a head attached to a collar at a first end of the cutting tool. A shank is located at a second, opposite end of the cutting tool. A central cavity extends inwardly from the first end toward the shank. An eddy current vibration absorber assembly is disposed within the central cavity. The eddy current vibration absorber assembly includes an absorber mass made of an electrically conductive material, a magnetic material proximate the absorber mass, and a support member for supporting the absorber mass within the central cavity. The eddy current vibration absorber assembly is tuned by selectively adjusting a distance between the absorber mass and the magnetic material.
