摘要： 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.

摘要： A vibration absorber assembly which includes a cantilever beam component having a proximal end and a distal end, wherein the cantilever beam component extends along a longitudinal axis between the proximal end and the distal end. A distal support element supports the distal end of the cantilever beam component, and an absorber mass is movable in at least a radial direction with respect to the longitudinal axis. First and second support media support the absorber mass with respect to the cantilever beam component. The first support medium contacts the cantilever beam component at a first support region of the cantilever beam component, and the second support medium contacts the cantilever beam component at a second support region of the cantilever beam component, the first and second support regions being located at different longitudinal positions along the cantilever beam component. Other variants and embodiments are broadly contemplated herein.
