Method of roll grinding - BONNER ANNE M.

[0028] The method of roll grinding of the invention is a cylindrical grinding process carried out with selected organic bonded grinding wheels having unusual wheel structures and physical properties. These wheels permit mill rolls to be surface finished faster and much more efficiently than was possible with methods of the prior art roll grinding using conventional grinding wheels.

Practical Roll Techniques - Grinding Balancing

2013-9-13  The correct way to measure concentricity on a grinding machine is 180º from wheel (back side), if the roll is supported on grinding seats. For example, if the grinding seat is out of round this form will be transferred to the roll shell by the grinding wheel. Run-out will not be seen on the wheel side but when a measurement is taken 180º away from the wheel side this error will be apparent.
