Abstract
Official abstract text for this publication.
The invention relates to a cutting tool, particularly for use in a tool chuck of a machine tool, including a tool shaft with a center longitudinal axis and a tool head. The tool head is connected to the tool shaft via a positive-locking connection, which locks the movement in the direction of the center longitudinal axis and the positive-locking connection is supplemented by a bonded connection, particularly a soldered connection.
First claim
Opening claim text (preview).
What is claimed is: 1. A cutting tool comprising: a tool shaft with a center longitudinal axis; a tool head; a profiled tenon disposed on the tool shaft; and a profiled mortise that is complementary to the profiled tenon, wherein the tool head is connected to the tool shaft via a positive locking connection that locks the movement in the direction of the center longitudinal axis and that the positive-locking connection is supplemented by a bonded connection; wherein the positive-locking connection is formed as a mortise-and-tenon connection between the profiled tenon and the profiled mortise. 2. The cutting tool according to claim 1 , wherein the tenon has a T-shaped profile with a top facing toward the mortise and a base facing away from the mortise. 3. The cutting tool according to claim 2 , wherein the base tapers in the direction of the top, when viewed cross-sectionally. 4. The cutting tool according to claim 1 , wherein the tenon has a profile with basic rectangular geometry and teeth protruding transversely with respect to the center longitudinal axis. 5. The cutting tool according to claim 1 , wherein the tenon has a profile with Christmas-tree-shaped geometry. 6. The cutting tool according to claim 1 , wherein a carbide and a tool steel or a high-speed steel are connected to one another via the positive-locking connection. 7. The cutting tool according to claim 1 , wherein: the profiled mortise is disposed on the tool head; and the tool head is connected directly to the tool shaft via the positive-locking connection. 8. The cutting tool according to claim 1 , wherein: a coupling element is placed between the tool head and the tool shaft; the profiled mortise is disposed on the coupling element; the coupling element is connected to the tool shaft via the positive-locking connection; and the coupling element is connected to the tool head. 9. The cutting tool according to claim 8 , wherein the tool head is attached to the coupling element in a reversible detachable manner. 10. The cutting tool according to claim 9 , wherein the tool head is formed as a replaceable milling head. 11. The cutting tool according to claim 1 , wherein the tool head comprises a support body and at least one cutting insert attached thereto in a reversible detachable manner.
