Abstract: A shrink fit adapter for a collet chuck has a rear holding area that can be mounted inside a collet chuck and a front receiving area for holding a tool shank. A through opening runs from a front face of the receiving area to a rear face of the holding area. A clamping area extends into the rear holding area. Here, the adapter is formed with a plurality of slots, which extend radially outward from the through opening and are distributed over the circumference. The slots are arranged in a central area of the through opening and the front ends of the slots are spaced apart from the front face of the receiving area.

Abstract: A rotatable cutting tool, which extends along a tool axis defining an axial direction, includes a cutting formation in a first axial longitudinal end region, which is configured for material ablation on a workpiece, and includes a screw-connection formation in a second axial longitudinal end region opposing the first, which is configured for screw connection with a coupling unit. The cutting tool includes key-contact surface formations diametrically opposing each other with respect to the tool axis, which are configured for torque-transmitting abutting engagement with key surfaces of a key. Each of the key-contact-surface formations includes at least two key-contact surface regions provided with spacing from each other in the circumferential direction about the tool axis, which key-contact surface regions are inclined away from each other such that they form a vertex projecting away from the tool axis.

Abstract: The induction coil unit for heating a component which is rotationally symmetrical relative to an axis, includes a plurality of coils arranged about the axis of the tool holder, with pole elements, which are movable radially with respect to the axis, of which pole elements each one consists of includes a stack of pole rods that can be moved relative to one another. A yoke ring connects the pole elements, which, when the coils are excited by alternating current in the tool holder, produce a magnetic flux running in the peripheral direction to inductively heat the tool holder. The pole rods of each pole element can be moved jointly by means of pinion rollers, wherein, however, slide couplings or the like are provided in the drive force transmission path between the individual pole rods so that the pole elements can adapt to different contours of the tool holder.

Abstract: According to the invention, for shrinking and expanding a tool in the bush part (3) of a tool holder, an induction coil unit (1), in which several polar parts (25) made of a soft magnetic material are radially adjusted in the yoke ring made of a soft magnetic material, is provided. Said polar parts have end faces (29) which are inclined in relation to the axis of rotation (7) of the bush part (3) and can be kept in a linear contact with a conical peripheral surface (31) of the bush part (3) which holds a the tool (11) in a press fit manner. In order to avoid possible local overheating of the bush part (3), the area (39) of the end face (29) parallel to the axis is connected on the output side of the tool to an area (33) of the end face (29) inclined in relation to the axis of rotation (7).

Abstract: A centering device for centrally chucking a rotary tool includes a socket on a mandrel of a tool holder. A tool arrangement includes a tool holder that has a mandrel, and including a rotary tool that is placed on the tool holder and includes a socket. In order to create a universal centering device that is easy to manufacture and can be used for a multitude of internal chucking units, and create a tool arrangement in which the rotary tool can be centered with high accuracy on the internal chucking unit, the centering device is designed as a closed centering ring which can be inserted between the rotary tool and the mandrel and which has an elastically deformable contour, and such a centering device is disposed between the mandrel and the rotary tool in the tool arrangement.

Abstract: 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).
