Principles of Grinding SpringerLink

Abstract. There are many types of grinding: “precision” and “rough,” internal, external, surface, centerless; using wheels or belts; and conventional or “super” abrasives. I believe they all act the same. When a moving abrasive surface contacts a workpiece, if the force is high enough, material will be removed from the part and the ...
