Abstract: A device for fine or finest processing of a rotationally symmetric work piece surface of a work piece (14), with a drive mechanism (12) for driving the work piece (14) around an axis of rotation (16), two guidance mechanisms (20, 22) acting in radial directions with respect to the axis of rotation (16) and at least one tool (38) acting in a radial direction, and a pressing mechanism (42) for pressing the work piece (14) against the drive mechanism (12), wherein the work piece (14) can be disposed between the drive mechanism (12) and the pressing mechanism (42). The pressing mechanism (42) acts in a pressing plane (74) that is offset from the axis of rotation (16) towards a space (78) in which the guidance mechanisms (20, 22) are disposed.

Abstract: This disclosure concerns a device for machining surfaces, e.g., superfinishing, polishing, grinding or lapping spherical shells or flattened domes of a workpiece, or, for example, a ball joint, using a tool having a machining stone with a workpiece receiver, a first drive for an oscillating motion about a first axis of the workpiece, a tool holder and a second drive for an oscillating motion about a second axis of the tool holder, whereby the axes are an angle to one another.
