Practical Roll Techniques - Grinding Balancing

13/09/2013  • Dampening effect of the machine. Roll balance is influenced by face length, core construction, and the deflection of a roll rotated at speed. This deflection is measured at the center of the roll face while the roll is turning at operational speed. It is especially important that deflection be corrected before covering. NOTE: Rolls are balanced for one speed. This speed should be as close ...
