A method for honing a rotationally symmetric, non-cylindrical bore includes the steps of limiting the stroke of a honing tool between upper and lower reversal points, continoulsy detecting the actual diameter of the bore at all points along its length between the upper and lower reversal points, continuously comparing the actual diameter of the bore to a specified target diameters for at least one of the upper or lower reversal points, continuously limiting the stroke to regions of the bore in which the actual diameter is smaller than the target diameter, continuously limiting the stroke to regions of the bore in which the actual diameter is smaller than the target diameter, and reducing the stroke of the honing tool step-by-step based on the detected actual values of the diameter of the bore, so that it only the regions of the bore that are machined in which the actual diameter of the bore is smaller than the target diameter corresponding to the detected actual values of the diameter.

Method for producing rotationally symmetrical, non-cylindrical bores with a honing tool, and honing machine which is designed and equipped for making a cylindrical bore into a conical bore

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