A TUNED VIBRATION ABSORBER FOR A CENTRELESS

Vibration testing showed that the natural frequency of the grinding wheel spindle was being excited by the process. A vibration absorber, or damper, was designed and fitted to the free end of the grinding spindle. The amplitude of vibration was therefore reduced, and workpiece roundness appreciably improved. The five-point lobing was eliminated. 1.
