    • A vibration reducing device for a machine tool reduces vibration generated in a tool support body supporting a tool. The vibration reducing device includes an attenuation inducing member and a pressing and fitting mechanism. The attenuation inducing member is brought into contact with the tool support body so as to generate a frictional force in a direction in which it acts as a resistance to the vibration generated in the tool support body. The attenuation inducing member has a rigidity in a direction conforming to a contact surface between the attenuation inducing member and the tool support body, which rigidity is higher than that of the tool support body. The pressing and fitting mechanism fits the attenuation inducing member to the tool support body in a pressed condition.
    • 用于机床的减振装置减少了支撑工具的工具支撑体中产生的振动。 减振装置包括衰减诱导构件和按压装置机构。 衰减诱导构件与工具支撑体接触,以便在其作为抵抗在工具支撑体中产生的振动的方向上产生摩擦力。 衰减诱导构件在与衰减诱导构件和工具支撑体之间的接触表面一致的方向上具有刚性,其刚性高于工具支撑体的刚性。 按压和装配机构将压缩状态下的衰减诱导构件配合到工具支撑体上。
