Claims

[Scope of utility model registration request]

An eccentric shaft is provided that projects downward from the arm of the robot and is eccentrically attached to the lower end of the tool shaft that is rotatably driven. A sleeve that is restrained and has a hole that opens downward; a grindstone holder that rotatably fits into the hole of the sleeve and holds a grindstone; a directional pin that protrudes from the grindstone holder at right angles to the axis; A rotation center bushing that is detachably fixed to the center of curvature of the planar outer periphery of the polishing surface and has a vertical hole; the bushing is rotatably fitted into the vertical hole of the bushing, and the directional pin is slidably engaged with the upper part of the bushing. A polishing tool comprising: a rotation center pin having a notch that allows the polishing tool to rotate;
