摘要:
The invention relates to a collet chuck (1) for clamping a preferably cylindrical tool shank with a chuck body (2) of a collet (3) and an union nut (4), which are matched in such a way that the collet (3) can be driven into the chuck body (2) by tightening the union nut (4) such that it secures the tool shank in the collet chuck (1) ready for operation, wherein the collet (3) and the union nut (4) are permanently connected to one another and at the same time connected in a rotatable manner relative to one another.

The invention provides a clamping system (1) for a rotary tool (70), for example a milling cutter or drill. The clamping system (1) includes a base element (10), a collet (30) and a clamping nut (50), said clamping nut (50) friction-locking the rotary tool (70) within the base element (10) with the collet (30). In order to avoid a relative rotation of the base element (10) and the collet (30), the clamping system (1) has a form locking anti-twist protection which blocks a rotation of the collet (30) relative to the base element (10).

A collet adaptor (10) including a body (11, 12) having forward and rear ends and an axial bore (17) extending through the forward and rear ends. A drawbar (13) disposed at least partly within the bore (17) for connection to a collet (14). The drawbar (13) is secured within the bore (17) and a biasing arrangement (42) acts on the drawbar (13) in a direction tending to shift the drawbar (13) rearwardly within the bore (17). The drawbar (13) is displaceable within the bore (17) against the biasing influence of the biasing arrangement (42) to shift forwardly within the bore (17).

An axially elongate dental machining portion includes a machining region machinable by a dental machining device, and a fixing region for fixing the axially elongate dental machining portion to a holder of the dental machining device. In the fixing region is a fixing projection oriented transversely relative to a longitudinal axis. In a condition of the machining portion being mounted in the holder, the fixing projection bears against a holding nose positioned in complementary relationship on the holder. The machining region has a machinable surface which has a maximum spacing relative to the longitudinal axis, measured normal to the longitudinal axis, and the fixing projection has a maximum spacing relative to the longitudinal axis, measured normal relative to the longitudinal axis, that is greater than the maximum spacing of the machinable surface relative to the longitudinal axis.

An adapter device for ceramic cutting machines (2) that includes an adapter plug (1) for the hole (8) of the tool holder (7) of a ceramic cutting machine (2. The plug (1) includes a hollow cylindrical shape with a stop (12) that performs an axial fixation in a direction of the plug (1) in the hole (8) of a tool holder (7) of the ceramic cutting machine (2); and a longitudinal slot (13) that leaves open the inner hollow space of the plug (1) along its entire length. The longitudinal slot (13) has a narrower segment in a part of the plug (1) that is nearest the end (21) having the stop (12), and a wider segment in the part of the plug (1) that is near the end (22) of the plug (1) opposite the stop (12).
摘要:
A tool holder includes a collet configured to be clamped to the shank of a tool and a pull-out protection element configured to secure the tool against being pulled out of the collet. The pull-out protection further includes a protection element such that pull-out forces acting on the tool are transmitted to the collet. The protection element is mounted so as to be moveable relative to the collet and has a wedge-shaped configuration as well as force-transmission surface. When the protection element is in a radially inner engaged position with the tool, the protection element is configured to be clamped to the cool and the collet so as to be self locking.

摘要:
A clamping device for clamping a work piece includes a chuck, a collet positioned inside the chuck, and a bayonet fastener operatively arranged so that the collet is fastenable in the chuck and is removable from the chuck solely by manual operation of the bayonet fastener without the use of auxiliary tools.

A pull-out preventer and milling collet that includes the pull-out preventer. The pull-out preventer is configured to prevent axial migration of a fluted milling tool out of the milling collet. The milling collet includes a through-hole extending from a rear-end aperture to an opposing cutting-end aperture of a basic body thereof. The pull-out preventer is located at the cutting-end aperture of the basic body.
摘要:
A chuck assembly and collet for retaining a commercially-available large-diameter, high-torque end mill (or similar) tool against axial pullout and against radial (or rotational) movement with respect to the assembly. The tool includes two axially spaced flat surfaces along the shank, one of which is coupled to the collet to prevent axial pullout and the other of which is coupled to the chuck to prevent rotation with respect to the chuck. The coupling to the chuck is accomplished by a ballclamp screw which extends through an aperture in the collet to the flat surface on the tool. The ballclamp screw has a flattened ball that is pivotally mounted in the screw's engagement and the pivotal mounting accommodates a few degrees misalignment between the shank's flat surface and the screw without significantly affecting the coupling therebetween.
