Abstract:
A machine for superfinishing an at least substantially cylindrical bearing surface having an axis of rotation on a workpiece, comprising an abrasive belt and three abrasive belt clamping members mounted in a triangle around said bearing surface and movable in directions that converge on the axis of rotation of said bearing surface, wherein each of said three clamping members has a surface facing said bearing surface and carries two applicator shoes rigidly fastened to the clamping member so as to project from said clamping member surface toward said bearing surface, said two shoes being spaced from each other in the circumferential direction of said bearing surface, each of the six shoes thus provided having a cylindrically curved abrasive belt applicator surface to press said abrasive belt against said bearing surface along a surface substantially limited to a generatrix parallel to said axis of said bearing surface.
