Abstract

PURPOSE: To essentially prevent the dulling phenomenon of the grindstone, and to perform the titled grinding work, by making the grindstone being closely thrust against the rolling mill's roll surface to reciprocate parallelly to the roll axis and also to reciprocate in the roll's rotating direction.
CONSTITUTION: In the roll grinding apparatus 1, the hydraulic pressure is applied to the hydraulic chamber 9 of the holding box 10 to whose tip the grindstone 2 is being loosely attached, from the hydraulic header 6 through the on-off electromagnetic valve 5 and the pressure regulator 4; hereby, the grindstone 2 is closely thrust against the surface of the work roll 8. Plural sets of the holding box 10 are arranged so as to prevent the generation of the dead space between the surface of the roll 8 and the surface of the grindstone 2; and the inclined bottom surface of the frame 11 is put upon the inclined guide frame 14; then, the frame 11 is driven by the reciprocating motion driver 12 so as to make the reciprocating motions in the direction of the roll axis and in the direction perpendicular to the roll axis. According to this method, since the ground surface always contacts with new grindstone surface, any kind of the grindstone can always perform the grinding work without causing the dulling phenomenon.
