Abstract (en)
A grinding machine tool (100) comprises a housing (10), a driving assembly (20) disposed in the housing (10), a grinding disc (30) driven by the driving assembly (20), and having a grinding surface (31) and a non-grinding surface (32), a switch (40) driving the driving assembly (20), and a pressing plate (50) disposed on the housing (10) and having a first state in which the switch (40) drives the driving assembly (20) to drive the grinding disc (30) when the pressing plate (50) is operated, and a second state in which the switch (40) stops driving the driving assembly (20) when the pressing plate (50) is not operated. The grinding machine tool (100) has a grinding disc braking structure (60) detached from the non-grinding surface (32) when the pressing plate (50) is in the first state; when the pressing plate (50) is in the second state, the grinding disc braking structure (60) moves toward the non-grinding surface (32) and contacts with the grinding disc (30) to stop the grinding disc (30) from rotating.
