Example Of Roll Grinding

Sep 13, 2013 Concentricity tolerance indicates how closely the roll shell surface follows the actual roll rotation center. For example, imagine a roll which has been ground perfectly round and straight (no run-out) and is then bent in the middle like a banana. Now, although the roundness measurement is perfect, when the roll is rotated there is run-out in the middle. The roll is out of concentricity tolerance
