ABSTRACT:
A grinding unit 5 comprises grinding wheel 20, a driving device 22 for driving the grinding wheel, and a shifting device 23. When the grinding wheel is subject to vibration of a work roll 1a, vibrating energy is absorbed by deflection of a plain wheel 52 which is integral with an abrasive layer 51 of the grinding wheel and has an elastically deforming function. A rail frame 7 is moved by rail moving devices 30 to tilt a grinding wheel spindle 21 with respect to an axis of the work roll 1a. The rail frame 7 is tilted in opposite directions with respect to the axis of the work roll between when the grinding unit 5 is positioned to grind one end side of the work roll 1a and when it is positioned to grind the other end side thereof. In an on-line roll grinding apparatus, vibration from the work roll is absorbed to enable precise grinding with good roughness of the roll surface without giving rise to any chattering marks, and one work roll can be ground by a single grinding unit up to both roll ends.
