how to control vibration in grinding machine

Practical Roll TechniquesGrinding Balancing
· The correct way to measure concentricity on a grinding machine is 180º from wheel (back side) if the roll is supported on grinding seats. For example if the grinding seat is out of round this form will be resulting in vibration at the ends of the roll for a given speed. The amplitude of such vibration is normally measured by a vibrometer.

ANALYSIS AND CONTROL OF VIBRATION IN GRINDING
· Control of vibration is done at different approaches. Damping method is one of the vibration controlling techniques in grinding machines. Damping is nothing but the interface between grinding machine and rubber material. The rubber is the essential material for controlling vibration because it has elasticity property and energy absorbing property. Damping characteristics of the rubber compound depends on the dynamic property which are a function of the elastomer. This rubber material was placed below the surface of the grinding machine. Again reading has to be taken for with load and without load. 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
