Abstract: The invention relates to a method for producing a calibrated combination (I) of parts. The combination (I) of parts comprises at least one first part (2) with a first contact surface (3) and a second part (4) with a second contact surface (5), wherein the parts (2, 4) contact each other via the contact surfaces (3, 5) in the combination (I) of parts; and the parts (2, 4) are designed to be free of an undercut at least with respect to an axial direction (6) and can be moved relative to each other along the axial direction (6) and thereby along the contact surfaces (3, 5) in the calibrated combination (I) of parts.
