Alignment device

The invention relates to an alignment device for the aligned and detachable fixing of at least one functional component (10), in particular in the form of a tool holder, to a further functional component (12), in particular in the form of a tool disk, around at least one alignment axis (14), wherein the two functional components (10, 12) have in each case at least one contact face (16, 18) for mutual contact with each other. Said alignment device is characterized in that both the one and the further functional component (10, 12) have at least one alignment part (22, 24), in that the respective alignment part (22) of the one functional component (10) is a constituent part of an alignment element (30) and forms an alignment face (26), which can be brought into at least partial contact with a positioning face (28) of the associated alignment part (24) of the further functional component (12) with a predefinable alignment force, and in that the predefinable alignment force is formed by the preload which is produced by a resilient deflection of the part (36) forming the respective alignment face (26) relative to the remaining part (34) of the alignment element (30), taking place as the functional components (10, 12) are fixed to each other.
