Claims

[Scope of Claim for Utility Model Registration] A movable table which is movably provided on the bed and has an object to be ground mounted on its upper surface, and an object to be ground which is disposed on one side of the bed and is on the movable table. a belt grinding mechanism for performing rough grinding on the object; a grinding wheel grinding mechanism disposed on the other side of the bed for performing finish grinding on the object to be ground after rough grinding; a drive means for a movable base that moves toward the mechanism or the grinding wheel grinding machine, and a movable base that controls the amount of rough grinding of the object to be ground by controlling the amount of movement of the movable base toward the belt grinding mechanism. An automatic tab grinding device for temporary assembly, comprising: a drive control means; and a grinding control means for controlling the amount of grinding of the object to be ground by the grinding wheel grinding mechanism.
