    Abstract: A cartride-type milling cutter (1) is provided having a cartridge mounting mechanism (13) that resists the centrifugal load applied to the cartridges at high rotational speeds. The milling cutter includes a generally cylindrical cutter body (3), at least one replaceable tool cartridge (11) having a trailing face (21) and a leading face (19) having a cutting insert (31) for cutting a workpiece, and a mounting mechanism for detachably securing the tool cartridge (11) onto the cutter body (3). The mounting mechanism (13) includes a recess (40) in the cutter body (3) for receiving the cartridge (11) that includes a radially canted wall for providing dovetail-type resistance to radial movement of the cartridge (11) and at least one compressively loaded set screw (50) in the cutter body (3) for compressively engaging the leading face of the cartridge in order to seat and retain it within the recess (40). During the operation of the cutter, the centrifugal load is substantially borne by the combination of the radially canted wall and the set screw (50). The mounting mechanism preferably also includes a screw (64) optionally radially-oriented, that passes through a through bore (62) in the sides of the tool cartridge (11) for providing additional insurance against the loosening or breaking away of the cartridge (11) during high speed operation.

    Abstract: A coupling device for high speed rotation applications comprised of a first member (112) about a longitudinal axis (114) having a collar (120) integrally attached to a solid base (122) and a second member (130) about a longitudinal axis (114) having a sleeve (136) which is receivable within the collar(120). When the first (112) and second (130) members are rotated, the sleeve (136) expands within the collar (120) to minimize or eliminate any clearance that may exist between the sleeve (136) and collar (120). The coupling device may, among other applications, be utilized for machine tools such as milling cutters.

    Abstract: The present invention entails a collet tool (10) for removing a collet (12) from a circumferential retainer or nose piece (14) and for inserting that collet or another collet into a retainer or nose piece (14). Specifically, the tool includes an elongated sleeve (40) having a collet receiving section (42) formed about one end and a plunger reciprocally mounted within the opposite end of the sleeve. To remove a collet from a retainer (14), the free end of the collet is inserted into the collet receiving section (44) and the sleeve (40) is pressed onto the collet (12) causing the collet (12) to be radially compressed and released from its associated retainer (14). To then eject the collet (12) from the sleeve, the plunger (50) is moved into engagement with the collet (12) and the collet (12) is pushed from the sleeve (40). Then, with the tool being free of any collet (12), another collet may be readied for insertion into a retainer (14) by inserting the rear portion of the collet (12) into the collet receiving section (44).

    Abstract translation: 本发明涉及一种夹头工具（10），用于从周向保持器或鼻部件（14）上移除夹头（12）并用于将该夹头或另一夹头插入保持器或鼻部件（14）中。 具体地说，该工具包括一个细长套筒（40），该细长套筒具有围绕一端形成的夹头接纳部分（42）和可往复安装在该套筒的相对端内的柱塞。 为了从夹持器（14）上取下夹头，将夹头的自由端插入夹头接收部分（44），并将套筒（40）压到夹头（12）上，使夹头（12）径向 压缩并从其相关的保持器（14）释放。 为了随后从套筒中推出夹头（12），柱塞（50）移动成与夹头（12）接合并且夹头（12）从套筒（40）推出。 然后，在工具没有任何夹头（12）的情况下，通过将夹头（12）的后部插入夹头接收部分（44）中，可以准备另一个夹头以插入保持器（14）中。

    Abstract: L'invention concerne un procédé et un appareil d'équilibrage d'un ensemble (10) d'outil rotatif rapide. Une paire d'anneaux d'équilibrage fermés (28) tournent autour d'une surface de support cylindrique (18) formée autour d'un porte-outil (12) rotatif, chaque anneau étant monté rotatif autour de ladite surface de support (18) indépendamment l'un par rapport à l'autre. Ledit porte-outil (12) est adapté pour recevoir et maintenir un outil coupant (16). Après avoir déterminé le déséquilibre dudit porte-outil (12) et dudit outil coupant (16), on règle rotativement lesdits anneaux (28) autour de ladite surface de support (18) afin de créer un déséquilibre dans les anneaux (28) d'outil, puis on règle la position de ces derniers (28) de sorte que le déséquilibre créé desdits anneaux (28) se trouve à l'opposé du déséquilibre déterminé dudit porte-outil (12) rotatif et dudit outil coupant (16).
