装置。[Claims for Utility Model Registration] A grinding device for grinding the circumferential surface of a roll of a rolling mill by pressing a plurality of grindstones against the circumferential surface of the roll, wherein the grindstone is provided at the tip of a rod and the pressing force for pressing the grindstone against the roll is applied. A plurality of hydraulic cylinders for pressing the whetstone are equipped with a pressure regulator to adjust the hydraulic pressure to adjust the hydraulic pressure, a hydraulic cylinder for oscillation that moves the multiple hydraulic cylinders for pressing the whetstone together in the axial direction of the roll, and the whetstone. An oscillation amount detection means that detects the amount of movement of the pressing hydraulic cylinder along the roll axis direction, and the position of the shaft end of the roll, the step position on the roll circumference, and the hardness distribution of the roll circumference along the roll axis direction are considered. Then, the pressing force of the grindstone required to grind the roll flat is preset in accordance with the axial position of the roll, and a pressure is applied to each grindstone whose axial position of the roll is determined from the amount of oscillation detected by the oscillation position detection means. A grinding device for a mill roll, comprising: control means for controlling the pressure regulator so as to apply a preset pressing force.
