Abstract (en)
[origin: US2001041523A1] A machine for grinding cylindrical bearing surfaces on parts, in particular journals and/or crank pins on crankshafts, using an abrasive belt, includes a support on which three abrasive belt clamping members are mounted in a triangle and mobile in directions that converge toward the axis of the bearing surface to be ground. Each clamping member carries at least one applicator shoe conformed to press the abrasive belt against the bearing surface along a surface essentially limited to a generatrix parallel to the axis of the bearing surface. The shoe is preferably made from an elastomer having a Shore hardness at most equal to 100 and has a cylindrically curved applicator surface with a radius of curvature less than the radius of curvature of the bearing surface.
