Abstract

PURPOSE:To reduce the changing frequencies for grinding and to improve the production efficiency by bringing a grinder for a rolling roll group installed in both top and bottom surface sides of a stock to be rolled in contact with plural rolling rolls in the rolling roll group to grind plural rolls. CONSTITUTION:A retractor cylinder 32 is actuated to shift a base frame 26 to a roll 10 side and to bring a grinding body 6 to abut on the roll 10. Then, a cylinder mechanism 24 is actuated to set the grinding body 6 in a prescribed angle; a cylinder 20 is actuated to reciprocately move a holder frame 8 in the axial direction of the roll 10, which concurrently is rotated so that the surface of the roll 10 is grinded. At the time that the surface of a backup roll 12 has flaws, the retractor cylinder 32 is retracted to put the base frame 26 over a guide rail 4, a cylinder 30 is extended to upwardly tilt a frame supporting table 16 from the frame 26. The grinding body 6 at the top of the holder frame 8 is abutted on the backup roll 12 to grind the surface.
