METHOD FOR GRINDING ROLL BY ON-LINE ROLL GRINDER DEVICE

摘要

PURPOSE:To perform grinding with less errors by measuring roll profiles before and after grinding, detecting a grinding capacity of a grinding wheel from the above data and correcting succeeding grinding amounts based on the grinding capacity. CONSTITUTION:A roll profile to be ground which is a difference between a profile measured by a roll profile detector 2 and a target roll profile is partitioned by a grinding amount per oscillation of a grinding wheel dependent upon the number of rotations of the wheel, wheel grinding capacity, etc. A crossing point of the grinding amount with the profile to be ground is found and a grinding space distance is decided, a grinding wheel 3 is pushed into only the grinding space distance, and the wheel 3 is oscillated by a grinding wheel post 4 to perform grinding. Hence, grinding with less errors is performed.
