<p>A planetary-gear-type parallel-surface processing machine of the present invention improves the ability of an upper surface plate (9) to follow materials to be processed. A rotation preventing pin (18) projects from the upper surface of the upper surface plate (9) at a position near the outer periphery thereof, the rotation of the upper surface plate (9) is prevented by abutting a stopper (19) supported by a bracket (21) disposed on a machine main body against a side of the rotation preventing pin (18), plural pulleys (12), (14) are disposed in a ring (13) mounted to the upper surface plate (9) and a suspension plate (15), and an endless wire cable (17) is stretched between the pulleys (12), (14) so as to support the vertical load of the upper surface plate (9). <IMAGE></p> |
