Abstract
A surface grinding machine has a motor-driven grinding disc supported in a carrier movably supported above the base and a tool holding fixture on the base which is rotatable about a laterally offset axis. A control assembly includes a contact arm which is movable into an operative position to guide the tool into the initial grinding position, and includes means for moving the grinding disc downwardly against the tool surface in a controlled fashion upon movement of the contact arm into an inoperative position. The tool holding fixture is rotatable about its axis as the grinding disc rotates to eliminate substantially circular grooves and scratches in the tool being ground.
