ABSTRACT:
A polishing machine comprises a vertical frame 1, a workpiece-carrier plate which is horizontally movable in at least one direction, and a support column 3 vertically movable in relation to the frame and supporting a polishing unit comprising a tool holder 9 carried by a slide 41 driven in translational motion by an eccentric device operated by an electric motor 8. The tool holder thus undergoes an alternating translational or reciprocating motion, and a hydraulic jack 50 is provided to urge the tool holder against the workpiece being polished. The structure for imparting the alternating translational motion is formed by an internal connecting rod-crank assembly 34, 46 mounted in the slide 41.
