Abstract
A tool arrangement with a screw-in tool and a tool receiver, the screw-in tool having a thread for engagement in a counter thread on the tool receiver. The counter thread and the thread have different thread contours and therefore, in the screwed condition, these adapt to one another by elastic deformation.
Claims16
A tool arrangement comprising:
- a milling cutter having a thread disposed therein;
- and
- a milling cutter receiver having a counter thread disposed therein;
- wherein the thread and the counter thread have different thread contours, one of the thread and the counter thread being more brittle than the other, and where a thread contour includes an entire length of the thread or counter thread in a longitudinal section;
- and
- whereupon engagement of the milling cutter with the milling cutter receiver, the less brittle of the thread and the counter thread elastically expands or compresses relative to the other such that the thread contour of the thread and the thread contour of the counter thread adapt to each other,
- wherein the milling cutter and the milling cutter receiver further comprise at least one support area formed by two conical contact surfaces or conical support surfaces having different taper angles;
- and
- wherein the two conical contact surfaces or conical support surfaces are directly adjacent to one another.
