Method of and machine for grinding a roll

摘要

A method and machine for grinding a rolling mill roll in which the grinding wheel is rotated against the working surface of the rotating mill roll and is displaced back and forth longitudinally along this surface and simultaneously or subsequently the surface is examined for defects by sensors capable of evaluating the geometry of the roll surface. The measured results are compared with stored images or data representing defects in the surface and measured surface defects are compared with the stored data and if they exceed a certain threshold or defect tolerance, an appropriate output is provided by the grinding machine.
