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
These machines are capable of producing a flat and parallel surface within .0005/ft and square within .0007/ft. Surface grinding is the most common of all grinding operations, and can easily be accommodated on any of our five surface grinders.
