Abstract: A grinding head unit is constituted by a grinding wheel, a drive device for rotating the grinding wheel, and a movement device for moving the grinding wheel. When vibration of a mill roll is applied to the grinding wheel, a plain wheel integral with an abrasive layer of the grinding wheel and having an elastically deforming function is deflected to absorb the vibration energy. The contact force between the abrasive layer and the mill roll is measured for determining a profile of the mill roll. The mill roll can be thereby ground into a target profile while absorbing the vibration transmitted from the mill roll and measuring the profile of the mill roll, without causing any chattering marks.

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.
