ABSTRACT:
A grinder capable of disassembling a pair of rolls of a rolling mill each having a pair of bearing assemblies on its opposite ends, separately grinding and reconditioning the disassembled rolls, and reassembling the reconditioned rolls. Included are a pair of opposed wheel stocks each having an abrasive wheel and both movable linearly along respective wheel guideways extending parallel to each other. Two pairs of opposed pivotal work carriers are disposed intermediate the pair of wheel guideways, with each pair of work carriers spaced from each other in a direction parallel to the wheel guideways. Each pair of work carriers are jointly movable between a common centerline position midway between the pair of wheel guideways, and a grinding position adjacent one of the wheel guideways. A set of fluid actuated work lifters are disposed adjacent the centerline position for loading the disassembled rolls on the respective pairs of work carriers, and for unloading the ground rolls therefrom, as the pairs of work carriers are successively moved to the common centerline position. Loaded on the respective pairs of work carriers, the rolls are ground in the grinding positions by being held against the abrasive rolls as the work carriers are pivoted and held in a slanting attitude. A pair of headstocks are provided for revolving the rolls being held against the abrasive wheels.
