摘要： An apparatus and method for balancing a high speed rotary tool assembly (1) is provided. The apparatus includes a rotary tool holder (3) having an axis of rotation (11), a cutting tool retainer (13) in the rotary tool holder (3) having a lockring (23) that circumscribes the axis of rotation (11) of the holder (3), and a pair of axially spaced balancing rings (35a, 35b) for balancing the entire rotary tool assembly (1) which are rotatably mounted around bearing surfaces (37) circumscribing the lockring (23) so as to be angularly positionable around the axis of rotation (11) of the tool holder (3). In the method of the invention, the unbalance of the tool holder (3) and cutting tool (17) is determined, and then the rings (35a, 35b) are rotatably adjusted about the bearing surface (11) on lockring (23) to create an unbalance which cancels out the determined unbalance of the tool holder (3) assembly.

摘要： A toolholder (1) of the type including a collet (5) integrally formed with a shank (3) is provided with an interface between a locknut (7) and collet (13) which substantially reduces the torque required to turn the locknut (7) into a position which radially collapses the collet segments (17). In this interface, one of either the inner locknut surface (23) or the outer surfaces of the collet segments (17) includes an engaging portion (56) for wedgingly flexing the collet segments (17) inwardly when the locknut is turned, and a non-engaging portion (58) disposed between the engaging portion (56) and the shank mounted ends of the collet segments (17). The non-engaging portion (58) reduces the torque required to turn the locknut (7) by reducing the binding forces that would otherwise occur between the ends of the collet segments (17) and the inner locknut surface (23). To further reduce torque, the collet portion interconnecting the collet segments (17) with the shank (3) of the toolholder is rendered thinner by the provision of circumferential grooves (72, 76) that make the collet segments (17) more flexible. Sealing rings (66, 74, 81) are seated in grooves (68, 72, 76) present in the interior defined by the collet segments (17) in order to prevent errant flows of coolant or debris from collecting between the collet segments (17) and the tool shank (9) gripped thereby.
摘要翻译：一种包括与柄（3）一体形成的夹头（5）的刀架（1）设置有在锁紧螺母（7）和夹头（13）之间的界面，其大大减小了转动锁紧螺母（7）所需的扭矩）进入径向塌缩夹头段（17）的位置。在该接口中，内锁紧螺母表面（23）或夹头段（17）的外表面之一包括用于在锁紧螺母转动时将夹头段（17）向内楔入地弯曲的接合部分（56），以及设置在接合部分（56）和夹头段（17）的柄安装端之间的非接合部分（58）。非接合部分（58）通过减少否则将在夹头段（17）的端部和内部锁紧螺母表面（23）之间发生的结合力来减小转动锁紧螺母（7）所需的扭矩。为了进一步减小扭矩，通过设置使夹头段（17）更灵活的圆周凹槽（72,76），将夹头段（17）与刀架的柄（3）互连的筒夹部分变薄。密封环（66,74,81）位于由夹头段（17）限定的内部中的凹槽（68,72,76）中，以防止冷却剂或碎屑的错误流动在夹头段（17）之间收集）和由此夹持的工具柄（9）。

摘要： The present invention is a tool holder for receiving an endmill or similar tool. The tool holder includes a shank portion (14) adapted to fit into the spindle of a machine, and a closed end collet (16) integrally formed with the shank portion. The collet includes an axial bore (30) for receiving the tool and a plurality of resilient collet segments (34) for gripping the tool. The collet segments are separated by a plurality of axially extending slots (32) which terminate inwardly from the forward end of a collet. A continuous tie ring (36) extends around the forward end of a collet and joins the plurality of collet segments together. The continuous tie ring provides for increased radial stiffness at the forward end of the collet which improves accuracy and repeatability of tool location. A lock nut (40) threads onto the collet to collapse the collet segments radially inwardly to grip the tool.
