A device for fine-machining a peripheral workpiece surface which is arranged eccentrically in relation to a workpiece axis of a workpiece, in particular of a pin bearing of a crankshaft, includes a rotary drive device for rotatably driving the workpiece about the workpiece axis, a pressing device for pressing a fine-machining tool against the peripheral workpiece surface, and a bearing device for supporting the pressing device on a frame. The device further includes a force application device which applies deceleration and/or acceleration forces on a bearing member of the bearing device, with the bearing member moving back and forth between two reversal positions when the workpiece rotates.
