摘要： A tool holder includes a holder body which in turn includes a flange portion. A plurality of threaded holes are formed in the flange portion. A weight balance adjustment member(s) is removably screwed into an appropriate threaded hole(s). The adjustment member includes a coming-out prevention mechanism for preventing the same from coming out of the threaded hole. In another tool holder, weight balance adjustment members are removably screwed into all the threaded holes, each of the adjustment members includes a coming-out prevention mechanism for preventing the same from coming out of the threaded hole, and a detachment prevention member is provided on the outer circumferential surface of the flange portion in order to prevent detachment of the adjustment members.

摘要： A tool holder is equipped with a tip run-out correction mechanism for correcting run-out of the tip of the tool. The tip run-out correction mechanism includes an annular stepped portion formed on a cylindrical support portion of a holder body; a ring member rotatably fitted onto the annular stepped portion; an eccentric cam disposed within the ring member, the eccentric cam extending radially through the ring member and being rotatable about a radially extending axis; and a pin disposed within the ring member to be movable along a direction parallel to the center axis of a flange portion of the holder body. One end of the pin is in contact with the eccentric cam, and the other end of the pin is in contact with a rear end face of a clamp sleeve which clamps a tool inserted into a chuck sleeve of the holder body. The eccentric cam is rotated so as to adjust press force that the pin applies to the rear end face of the clamp sleeve, to thereby elastically deform a base end portion of the chuck sleeve in a radial direction in such a manner that tip run-out of the tool approaches zero.
摘要翻译：工具架配备有用于校正工具尖端的磨损的尖端径向校正机构。刀头径向校正机构包括形成在保持器主体的圆柱形支撑部分上的环形阶梯部分; 可旋转地装配到所述环形台阶部分上的环件; 设置在所述环构件内的偏心凸轮，所述偏心凸轮径向延伸穿过所述环构件并能够围绕径向延伸的轴线旋转; 以及设置在所述环构件内的销以能够沿着与所述保持器主体的凸缘部的中心轴线平行的方向移动。销的一端与偏心凸轮接触，并且销的另一端与夹紧套筒的后端面接触，夹紧套筒夹持插入保持器主体的卡盘套筒中的工具。旋转偏心凸轮以调节销向夹紧套筒的后端面施加的压力，从而使卡盘套筒的基端部沿径向弹性变形，使得尖端径向的工具接近零。
