Combination of a receiving body and an insert, the insert being particularly a tool or workpiece holder, a receiving body and an insert of such a combination

摘要

The combination has a finely machined, dimensionally stable plane surface (17) extending at a right angle with respect to a collet pin axis. A cone surface is arranged at an axial distance from the plane surface, and includes a tapered end facing towards the plane surface such that the plane surface and another plane surface (6) are superimposed with a collet pin (15) inserted in a receiving bore (4). The cone surface and another cone surface (9) are clamped against each other by twisting the collet pin relative to the receiving bore while a bias presses the plane surfaces against each other.
