Abstract:
1. A method of machining the circumferential surface of a bore by rough-honing using a honing tool received by an overhung-mounted working spindle and provided with honing stones, said working spindle having a longitudinal axis (M A ) and said honing stones being feedable in radially outward direction, in which, at the start of the machining process, the honing tool is inserted eccentrically into the bore such that the longitudinal axis (M B ) of the bore has a certain offset (S) from the axis (M A ) of the working spindle and the honing stones only partially work along the circumferential surface of the bore in a partial cut, and, when the honing stones are pressed in said radially outward direction during the machining process, the longitudinal axis of the bore (M B ) approaches the longitudinal axis of the working spindle (M A ) until the circumferential surface of the bore is machined with complete coverage everywhere in a full cut eliminating the offset (S) and any angle between the axes (M A , M B ), and subsequently the circumferential surface is uniformly honed with said full cut.
