Our invention relates to a machine for grinding and polishing true surfaces, as distinguished from planing or filing such surfaces, and in which is used a table that has a traversing motion past the side of the grinding and polishing wheel, and at right angles to the axis of said wheel, with suitable appliances for driving, moving, and adjusting the several parts of the machine to adapt them to the work of grinding true surfaces.
