Oct 08, 2019Two factors affect the vibration of the grinding wheel. One is that the grain size of the grinding wheel is not uniform, and the center of gravity is unstable when it is rotated. The other is that the inner hole is not standard and too large. For example, the grinding machine flange hole diameter is 31.75mm, but the grinding wheel hole diameter

Measuring vibration on precision grinding machines
Mar 10, 2016Vibration forms. Common forms of vibration on grinding machines tend to fall into two categories force vibration and self-excited vibration. Force vibration includes wheel imbalances, damaged bearings, bad motors, or grinding wheel imbalances. Force vibration can be present even when the grinding wheel is not in contact with the workpiece.
