Reduction of grinder vibration by balancing.

INDUSTRIAL HEALTH, 1984
Hand-transmitted vibration generated by a grinder is considered to be harmful to workers' health. It is found that balancing a grindstone can effectively attenuate vibration if the magnitude and direction of unbalance can be properly adjusted by use of a field balance detector. An effective automatic dynamic balancer consisting of a toroidal metal tube
