DRESSING METHOD FOR GRINDING WHEEL FOR ROLLING ROLL

摘要

PURPOSE:To improve grinding efficiency by disposing a dressing tool to the non-contact part of a grinding wheel and rolling roll and pressing the tool to the side end face of the grinding wheel during grinding. CONSTITUTION:A supporting shaft 4 of the grinding wheel 3 is supported by a bearing box 5 and is pressed to the outside peripheral surface of a work roll 1 by the operation of a hydraulic cylinder 6. The dressing tool 10 is provided to the non-contact part of the wheel 3 and the roll 1 and is pressed to the bore part on the grinding surface of the wheel 3. The tool 10 is pressed always under the specified force to the wheel 3 by the operation of a hydraulic cylinder 11. The tool 10 follows up consequently the wear of the wheel 3 even if the wheel wears. The tool 10 removes successively the build-up part of the wheel 3. Since the build-up part which is the cause for the oscillation of the wheel 3 is removed, the stable grinding with the wheel 3 is made possible. The grinding efficiency is thus improved.
