Abstract: A method is proposed for honing conical bores.

Abstract: 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.

Abstract: The invention relates to a machine for creating non-cylindrical bore surfaces having a machine spindle (5), to which a machining tool (2-06, 3-04) can be connected, onto which a feed movement is transferred via a feed means (1-10). A direct axially parallel acting linear drive (1-06) is provided in the tool fitting unit (1) associated with the machine spindle (5) for fine feeding, the feed movement of which overlaps the first mentioned feed movement, and the actuating means (1-05) of which acts upon a feed (1-03) that is disposed together with the machining tool (2-05, 3-04) and the means for deflection (1-031, 1-032) of the feed movement in a tool unit (2, 3) that can be exchanged on the tool fitting unit (1).
