Abstract:
Since a tool holder is formed of a structure which is elastically deformed by a centrifugal force produced as the tool holder rotates around a rotation center axis, the rotation radius of a tool with a cutting edge directed to the rotation center axis varies from zero to an arbitrary value. The structure of the tool holder includes two beams elastically deformable to the same degree in opposite directions by the centrifugal force, and centrifugal force components acting on the two beams cancel each other so that a rotation balance is maintained even when the rotational speed of the tool holder is changed.
