METHOD FOR GRINDING ROLL BY ON-LINE ROLL GRINDER DEVICE

摘要

PURPOSE:To grind a roll stock into a target profile by partitioning a profile to be ground by differential parts between a measured roll profile and a target profile by a grinding amount per oscillation and changing a grinding position per oscillation based on the above partition. CONSTITUTION:A roll profile detector 12 is movable in a direction orthogonal to the roll axis, approaches a roll 11, is in contact with the peripheral surface of the roll 11, and measures a roll profile of the roll 11 for roll profile measuring operation. A grinding wheel post 14 oscillates together with a grinding wheel 13 in the roll axial direction and pushes the wheel 13 onto the roll peripheral surface in a grinding space to grind the roll 11 by the wheel 13. A roll profile to be ground which is a difference between a measured and a target profiles is partitioned by a grinding amount per oscillation dependent upon the number of rotations of the roll 11, wheel grinding capacity, etc. Based on that partition, a grinding position is changed every oscillation and grinding is performed according to a measured roll profile. Hence, grinding errors are reduced.
