本发明公开了种工具夹持器，所述工具夹持器包括切削工具，所述切削工具安装到在所述工具夹持器的第末端处附接到套环的头部。柄位于所述工具夹持器的相对第二末端处。中心空腔从所述第末端朝向所述柄向内延伸。无源吸振器组件设置在所述中心空腔内。所述无源吸振器组件包括吸振器主体和附接到所述吸振器主体的吸振器盖。所述吸振器主体具有第末端、与所述第末端相对的第二末端，以及形成于所述第二末端中的个或多个空腔。所述吸振器主体中的所述个或多个空腔部分地或全部地填充有金属或陶瓷的颗粒或粉末以提供用于抑制所述工具夹持器的振动的颗粒阻尼。 A toolholder includes a cutting tool mounted to a head attached to a collar at a first end of the toolholder. A shank is located at a second, opposite end of the toolholder. A central cavity extends inwardly from the first end toward the shank. A passive vibration absorber assembly is disposed within the central cavity. The passive vibration absorber assembly includes an absorber body and an absorber cap attached to the absorber body. The absorber body has a first end, a second end opposite the first end, and one or more cavities formed in the second end. The one or more cavities of the absorber body are partially of wholly filled with metal or ceramic particles or powders to provide particle damping for suppressing vibration of the toolholder.
