A device for producing a non-cylindrical inner surface of a bore having machining tools arranged along the bore's circumference and can be radially advanced towards the bore's inner surface includes a primary advancing system having an axially movable advancing rod for actuating the machining tools, thus exerting a primary force onto a machining tool, which is radially advanceable towards the bore by the primary force, which is dynamically superimposed with a secondary force generated by a secondary advancing system that forms an integral unit together with the primary advancing system or can be constructed in a modular manner. The secondary advancing system activates dependent on a current rotational movement and/or a stroke movement of the primary advancing system, a current tool position, or a specified advancing force, or the secondary advancing system activates at a specified time. In the process, the tool is already widened by the primary advancement.
Device for generating a noncylindrical inner surface (10) of a bore (4) with machining tools (9) arranged along the circumference of the bore (4) and radially fed up to the noncylindrical inner surface (10) of the bore (4), wherein the device comprises a primary advancing system (14), which comprises an axially movable feed rod (13) for activating the machining tools (9) and thereby creates a primary force (Fz) on at least one machining tool (9), by which the at least one machining tool (9) can be radially fed up to the bore (4), characterized in that a secondary advancing system (16) is provided coaxially to a primary advancing system (14), and the advancement movements of the primary advancing system (14) and the secondary advancing system (16) are added to give an overall advancement movement which is transmitted to all cutting blades (9) of a downstream tool (5).
