  • the user operates the pressing plate 74 to drive the motor 71 to drive the working shaft 72, so that the grinding disc 75 rotates with the working shaft 72 for grinding.
  • the user When the user wants to stop grinding, the user releases the pressing plate 74 to stop the motor 71 from driving the working shaft 72. At this time, although the grinding disc 75 stops being driven, the grinding disc 75 will continue to rotate due to an inertia of the motor 71 and the working shaft 72 and its own inertia until an inertial kinetic energy is consumed.
  • the aforementioned phenomenon means that although the user has stopped driving the motor 71, the grinding disc 75 will continue to idle, as a result the user cannot replace consumables of the grinding machine tool 70 during this period, and also the safety of the user is easily affected.
