The invention concerns a device for abrading a wall of stone or concrete material. The invention comprises a shell ( 2 ) with which is operationally connected an abrading head ( 1 ), and a carriage intended to move at least along the surface and support the shell ( 2 ) movably so that the abrading head ( 1 ) by means of the movement of the shell ( 2 ) performs an upward and downward abrading movement. The abrading head ( 1 ) is of the type which has a rotatably mounted and driven planet wheel with a number of driven abrading discs rotatably mounted thereon and fitted with abrading elements. The device has an element for placing the abrading head ( 1 ) with a predeterminable force against the surface to be abraded.
