Abstract: 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.

Abstract: The present invention relates to a honing tool and a method for honing the inner surface of an opening in a workpiece with a honing tool according to the invention.

Abstract: A honing tool has a tool body and shells disposed on the tool body. Honing stone sets each provided with two or more honing stones are provided. The shells each support one of the honing stone sets. Guide bars of the honing tool are placed against the bore and a portion of the bore is conically honed with decreasing stroke of the honing tool, wherein a lower reversing point of the honing tool remains substantially unchanged. Honing is terminated as soon as an upper reversing point has reached a predetermined terminal value. Alternatively, a portion of the bore is conically honed with a constant stroke of the honing tool, wherein reversing points of the stroke of the honing tool remain substantially unchanged and a feeding force pressing the honing stones against the bore is controlled as a function of a position of the honing tool in the bore.

Abstract: A method is proposed for honing conical bores.

Abstract: 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.
