Balancing, grinding wheels

Electromechanical grinding wheel balancing systems are available which measure the vibrations caused by an unbalanced grinding wheel and suitably move weights flanged to the outside of the grinding wheel, or inserted in the machine spindle. This eliminates the need to manually pre-balance. 

Balance Balancing. A grinding wheel is said to be in static balance if it will remain at rest, in any position, when it is mounted on a frictionless, horizontal spindle such a wheel is also in dynamic BALANCE if, when rotated, there is no whip or vibration. The process of testing for balance, and the making of any necessary adjustment to the wheel, is known as balancing. 

Grinding wheels require balancing before use, to minimize vibration because of the high rotational speeds. 

It is impossible to produce good-quality work on any grinding machine if the wheel Is out of balance, thus setting up vibrations through the spindle.
