  • Polishing machine with pneumatic tool pressure adjustment
    Patent number: 5325636
    Abstract: A polishing machine comprising a frame 1, a mobile polishing head 2 mounted on the frame, an abrasion tool 10, and a reciprocating slide 7 for causing the tool to polish a contacted object. The tool is mounted on a tool holder 9 fitted with a pneumatic system 36, 38; 50 producing a dual adjustment of the bearing pressure generated by the tool 10 on the object P being polished.

  • Polishing machine having combined alternating translational and rotational tool motion
    Patent number: 5287658
    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.
