ABSTRACT:
A grinding machine includes a driving unit, a grinding wheel unit, an abrasive belt unit and a dust-collecting device. The dust-collecting device includes a dust-discharging unit and a dust-guiding unit. The dust-discharging unit includes a dust-collecting seat disposed fixedly on a side cover of the grinding wheel unit, and a suction fan assembly disposed within the dust-collecting seat. The dust-guiding unit includes a conduit communicated with a dust-receiving chamber in the grinding wheel unit and an accommodating chamber in the abrasive belt unit. The grinding wheel unit, the abrasive belt unit and the suction fan assembly are driven by the driving unit. Dust is induced by the suction fan assembly to move from the dust-receiving chamber and the accommodating chamber into the dust-collecting seat.
