Abstract (en)
An electric grinding machine tool (10) comprises a grip body (11), a grinding disc (15) and a battery (16), the grip body (11) is arranged with a tool shaft (114) connected with the grinding disc (15), a driving component (115) capable of rotating the tool shaft (114), a circuit board (116) electrically connected with the driving component (115) and the battery (16), and the grip body (11) has a battery mount (121). The circuit board (116) is not perpendicular to the tool shaft (114), the circuit board (116) and the battery mount (121) are respectively positioned on opposite sides of the tool shaft (114), and a line (122) passes through the circuit board (116), the battery mount (121), and the tool shaft (114). By changing the position of the circuit board (116), the gravity center of the grip body (11) is reduced to improve stability of a grinding operation.
