The fan 14 rotates, so that the metal dust generated by grinding passes through the wind tube 12 and the connecting pipe 18 into the filter box 17 for filtration, thereby reducing the impact of the metal dust on the environment. In addition, since the fan 14 rotates above the grinding disc 11, the circulation of air around the grinding disc 11 is accelerated, so that the heat generated by the grinding disc 11 during grinding can be sucked away together with the dust, thereby reducing the temperature of the grinding disc 11.
