Mar 10, 2016· 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.

Sep 01, 2018· In a production-grinding operation, waviness on the part surface is a potential clue that the machine or process has developed a vibration problem. The effect might be seen in inspection, or if there is a lapping or polishing step, more time might be spent during that step removing the waves ...
The reading obtained from without load is 2.8mm/s and the reading obtained from with load is 25 mm/s. Thus the severity of the vibration is reduced by using the damping method. 6. CONCLUSIONS The study reveals that the vibration was measured in grinding machine. This was the one of the major hazards in grinding machines.
Vibration-Assisted Grinding Vibration assisted grinding is a grinding method in which a certain frequency of vibration with an amplitude of about 10 µm is superimposed to the cutting tool or the workpiece to achieve better cutting performance. When a high frequency vibration (more than 16 kHz) is applied to the cutting
