Abstract (en)
An electric tool grinding machine (20) and a grinding disc cover (26) thereof, the machine (20) includes a grip body (21), an electric motor (22), a grinding disc (24), and an airflow generating member (25). When the motor (22) rotates, the member (25) forms a heat dissipation airflow (40) in the grip body (21). The grinding disc cover (26) is assembled with the grip body (21) and covers the member (25) therein. The grinding disc cover (26) includes a cover body (261), an assembly port (262), and a release port (263) facing the grinding disc (24), the cover body (261) does not have a vent hole other than the assembly port (262) and the release port (263), when the release port (263) is viewed from the assembly port (262) toward the release port (263), an inner wall of the release port (263) has a flow guiding section (264), an air outlet section (266) with a slope different from that of the flow guiding section (264), and an arcuate diversion section (265) connecting between the flow guiding (264) and air outlet sections (266).
