PROBLEM TO BE SOLVED: To provide a polishing device for an electrode and an automatic system for the same, which suppresses swaying of an electrode during polishing, and promptly corresponds to polishing work of an electrode of each welding machine even when the plurality of welding machines are installed.SOLUTION: The polishing device 1 including a file 3 formed with abrasive grain faces on the front and back, a cylinder 4 linearly reciprocating the file 3 in a direction orthogonal to an electrode axial direction, a floating mechanism 5 allowing the movement of the file 3 in the electrode axial direction by a reaction force received from a fixed electrode, and a movable electrode guide member 7 bored with a movable electrode guide hole 6 inserted with the tip periphery of a movable electrode and suppressing the swaying of the movable electrode during polishing is attached to a robot arm R1 moving in three dimensions, and both electrodes are polished by pressing the file 3 against the fixed electrode by the robot arm R1 and pressing the file 3 against the movable electrode by a pressurizing cylinder. |
