摘要： A polycrystalline diamond composite cutting insert (46) for attachment to a tool so that the cutting insert engages a work material when the tool is in operation. The cutting insert comprises a substrate (48) and an polycrystalline diamond composite layer on the substrate. The polycrystalline diamond composite layer has a transition region (50), bonded to the substrate, comprising a composite polycrystalline material in which the cemented carbide pieces, which comprise between about 40 volume percent and about 80 volume percent, and the diamond crystals are interspersed in one another. The polycrystalline diamond composite layer further includes an outer region (52), bonded to the transition region, comprising a composite polycrystalline material in which the cemented carbide pieces, which comprise between about 5 volume percent and about 45 volume percent, and the diamond crystals are interspersed in one another.

摘要： A ball lock assembly having a cutting head (22) and a locking component (24) including a lock rod (94) carrying at least one locking member (105). A positioning assembly (50) operatively connects to the lock rod so that one can move the lock rod between a locked position and an unlocked position. In the locked position the locking member engages the cutting head to hold the cutting head to the locking component. In the unlocked position the locking member does not engage the cutting head so that the cutting head is not held to the locking component.

摘要： The present invention relates to a milling cutter (10) having a cutter body (12) and a plurality of replaceable tool cartridges (16) circumferentially spaced about the outer periphery of the cutter body. An adjustment mechanism permits adjustment of the tool cartridges (16) in the direction parallel to the axis of rotation of the cutter body (12). The adjustment mechanism includes an adjustment screw (52) threaded into a corresponding bore (54) in the cutter body (12). The head (56) of the adjustment screw (52) projects into an inclined throughbore (60) in the tool cartridge (16). When the adjustment screw (52) is turned, the head (56) of the screw bears against the inner surface of the throughbore (60) causing the tool cartridge (16) to be axially displaced. A locking screw (62) is tightened to secure the tool cartridge (16) in place after it has been adjusted.

摘要： An expandable holding device for holding a component (115) in which the clamping force is brought about by the solidification and expansion of a fusible alloy (132). The alloy (132) is contained in an expansion chamber (130) defined in part by a thin-walled, expansion sleeve (122). The alloy (132) has a low melting point and expands when it solidifies. The pressure caused by expansion of the fusible alloy radially expands the expansion sleeve (122) causing the expansion sleeve to grip the component (115). To release the component, the alloy (132) is heated and liquified so that the expansion sleeve (122) returns to an unexpanded condition.
