    Abstract: An excavation cutting tool holder retention system. The cutting tool holder retention system includes a cutting tool holder having a holder engagement surface and a support block having a tool holder bore into which the cutting tool holder is inserted. A pin having a pin engagement surface is movably mounted to the support block such that the pin engagement surface may be moved to engage the holder engagement surface. At least one of the holder and pin engagement surfaces defines an inclined surface such that when the pin engagement surface is moved to engage the holder engagement surface, the shank portion of the cutting tool holder will be drawn into the tool holder bore. In the preferred embodiment, at least one of the shank portion of the cutting tool holder and tool holder bore is tapered such that the shank portion of the cutting tool holder will be drawn and wedged into the tool holder bore of the support block when the pin engagement surface is moved to engage the holder engagement surface.

    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: A rotary tool holder (20) includes a shank (58) having a flange (66), a tapered outer surface (64), and front and rear contact portions (60). The tapered outer surface (64) corresponds to the tapered bore of a spindle, and flexible circular cantilevers (70, 103) are provided at one or both contact portions such that a free end (76, 105) of the cantilevers expands radially due to centrifugal force to maintain contact with the tapered bore (53). The shank (58) can be formed from an inner member (113) and a sleeve (115) disposed thereover, in which portions of the sleeve (115) form the circular cantilevers. The circular cantilevers (256) can also be formed by a cavity (260) created in the shank (253). Alternatively, instead of circular cantilevers (256), the shank of the tool holder can have a taper which is optimized for a certain speed, wherein the taper of the shank (403) has a first taper at rest and a different taper (&PHgr;2) at a desired speed.

    Abstract: The present invention entails a method and apparatus for balancing a high speed rotary tool assembly (10). A pair of closed balancing rings (28) are journalled about a cylindrical bearing surface (18) formed around a rotary tool holder (12) with each ring being rotatively mounted about the bearing surface (18) independently of each other. The tool holder (12) is adapted to receive and hold a cutting tool (16). After determining the unbalance of the tool holder (12) and cutting tool (16), the rings (28) are rotatively adjusted about the bearing surface (18) to create an unbalance within the tool rings (28) and the position of the tool rings (28) is adjusted such that the created unbalance of the tool rings (28) is disposed opposite the determined unbalance of the rotary tool holder (12) and cutting tool (16).

    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.
