An orbital table assembly having a top plate which can be made to orbit or translate in a path without rotating, and having a fixed base plate under said top plate and a linkage plate between the two other plates, while an orbiting cam secured to the top plate imparts orbital motion thereto. A first set of arms is provided to secure the linkage plate to the base plate to prevent rotation of the linkage plate while permitting linear lateral movement in one direction only, and a second set of arms is provided secured to secure the top plate to said linkage plate to prevent rotation of said top plate while permitting linear lateral movement in a single direction perpendicular to the aforesaid direction.

Oscillatory or translational table for machine tools

A method is provided for making improved molded abrasive tools by applying centifugal force and/or vibratory action to the abrasive particles during the molding operation. The abrasive is thereby forced and/or sifted preferentially into a closely packed surface layer with close conformity to the mold surface.
