Grinding wheel safety operation regulations

After the grinding wheel is installed, the protective cover must be reinstalled, and then the trial rotation is carried out. Grinding wheels with a diameter less than 400 mm should be idle for 2 minutes; wheels with a diameter greater than 400 mm should be idle for 5 minutes. When the grinding wheel rotates, no obvious vibration is allowed.
