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

A method and suitable honing tools for honing conical bores are proposed.

A dressing device for dressing honing stones is provided with a base body and a mounting device for mounting the dressing device in a grinding machine. The base body has at least one honing stone receptacle that is a pocket. Honing stones are inserted and secured in the honing stone receptacles and the abrasive coating of the honing stones are ground by the grinding machine. A set of honing stones that is required for furnishing a honing tool can be dressed by one mounting action in the dressing device and can be inserted into the honing tool so as to be positioned exactly at the same radial position without requiring additional machining.
