A finishing device includes a finishing belt, a finishing belt holding device, a first drive configured to rotationally drive a workpiece about a workpiece axis, and a second drive configured to oscillate the workpiece and the finishing belt relative to another along the workpiece axis. The finishing belt holding device has a holding section configured to hold a portion of the finishing belt. The portion has an active area configured to finish a circumferential workpiece surface. The portion extends in a plane which is vertical when referring to the direction of gravity and extends in a horizontal direction when referring to the direction of gravity and when viewing in the running direction of the finishing belt. The finishing device includes a workpiece holding device defining a workpiece holding axis which is vertical when referring to the direction of gravity.

A honing assembly, a sanding assembly and a turning machine for performing an operation on a workpiece. The turning machine may include a rotatable machine housing operable to rotate around the workpiece; a first attachment including a first portion engageable with and operable to remove material from a workpiece, the first attachment having a first configuration, such as a honing attachment; and a second attachment including a second portion engageable with and operable to remove material from a workpiece, the second attachment having a second configuration, such as a sanding attachment, different than the first configuration, each of the first attachment and the second attachment being selectively supportable one at a time by the machine housing to operate on a workpiece.

Method and Device for Producing Non-Cylindrical Bores with at Least One Recess by Honing

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.
