The device (10) has a driving device (52) generating oscillating pivoting movement of a finishing tool holder (26) to hold a finishing tool (28). The holder is guided at a guiding device (54) in a pivotable manner around a virtual pivot axis, where the guiding device defines a curved guide track (24). The driving device has a driving element (36) i.e. connecting rod (38), that drives the holder along a drive path (58), where the path runs concentric to the track. The driving element is driven by a linear drive (57), and the guiding device has an arc rail (22) connected with the holder. |
