The purpose of the present invention is to easily perform a separating work of a grinding wheel. A grinding separating unit (30) comprises; a first inlet pipe (31) which passes through the inner side of a rotary shaft (24) in a longitudinal direction; a second inlet pipe (32) which is connected to the first inlet pipe (31) and is connected to a inlet (201) which is arranged on a mounting surface (200) of a wheel mount (23); and a guide unit (37) which guides a grinding wheel (22) and an inlet valve (33) which converts the absorption from the inlet (201) and the prevention of the absorption to a predetermined position. The grinding separating unit (30) guides and maintains that the grinding wheel (22) is not dislocated to the mounting surface (200) of the wheel mount (23) through the guide unit (37) by opening the inlet valve (33). Therefore, the separating work of the grinding wheel (22) is easily performed without a screw. |
