Abstract

A grinding machine tool comprises a housing, a driving assembly disposed in the housing, a grinding disc driven by the driving assembly, and having a grinding surface and a non-grinding surface, a switch driving the driving assembly, and a pressing plate disposed on the housing and having a first state in which the switch drives the driving assembly to drive the grinding disc when the pressing plate is operated, and a second state in which the switch stops driving the driving assembly when the pressing plate is not operated. The grinding machine tool has a grinding disc braking structure detached from the non-grinding surface when the pressing plate is in the first state; when the pressing plate is in the second state, the grinding disc braking structure moves toward the non-grinding surface and contacts with the grinding disc to stop the grinding disc from rotating.
