  • Patent number: 10160087
    Abstract: A honing method for machining the inner surface of a bore in a workpiece via at least one honing operation using an expandable honing tool with an annular cutting group. The method includes coupling of the honing tool to a working spindle of a machine tool, and; inserting the honing tool into an inlet of the bore with the cutting material elements retracted, until it is in a final insertion position, in which the cutting group is located in an end region of the bore. Then the honing tool is turned and the annular cutting group is simultaneously expanded to create a cylindrical widening of the bore, followed by withdrawal of the honing tool from the bore with simultaneous turning of the honing tool in such a way that the bore is successively further widened in the direction of the inlet side.
