Permissible unbalance range

Since the grinding wheel is installed in a grinding machine and used high speeds, grinding wheel balance is important. Use of the grinding wheel in an unbalanced way will generate vibrations and chatter at the grinding surface of the machine, which have a bad effect on the finished surface, processing precision and the grinding machine itself.

In most case, however, static balance should be adequate. JIS indicates the permissible unbalance range according to peripheral speed as follows:

mb : mass of weight (g), m : mass of grinding wheel (kg)
