A finishing machine with at least two finishing stones and a stone turning unit is proposed, in which the stone turning unit may be coupled to a rotary drive of the workpiece holder. A separate drive for the stone turning unit may thus be omitted, which results in a reduced weight of the stone turning unit and therefore lower drive power requirement of the stone turning unit and an improved processing quality.

Finishing machine with stone rotating unit

A device for fine or finest processing of a rotationally symmetric work piece surface of a work piece (), with a drive mechanism () for driving the work piece () around an axis of rotation (), two guidance mechanisms () acting in radial directions with respect to the axis of rotation () and at least one tool () acting in a radial direction, and a pressing mechanism () for pressing the work piece () against the drive mechanism (), wherein the work piece () can be disposed between the drive mechanism () and the pressing mechanism (). The pressing mechanism () acts in a pressing plane () that is offset from the axis of rotation () towards a space () in which the guidance mechanisms () are disposed.
