Equipment for grinding external rings of roller bearings includes a supporting pin of a bearing to be ground, a stop extending outwardly from the supporting pin for axial positioning of a side of the bearing, a sliding flange on the pin which can be positioned to rest on the other side of the bearing, a clamping nut which can be firmly positioned on a complementary portion of the pin, skids preloaded by springs situated on opposite sides of the bearing, and a guiding element on the opposite side of the stop, which receives a structure carrying a pair of contrast rolls movable to be engaged with the external ring of the bearing creating a radial force thereon, which can be predetermined and regulated by a maneuvering element to eliminate the clearance of the bearing in the radial direction. A machine for housing equipment of the above specified type.

A method for classification of defects and running of grinding of lamination cylinders includes identifying defect areas in a map illustrating a plurality of surface measurements of a cylinder. The method includes calculating, for each area identified, a plurality of parameters. The method includes identifying a type of defect associated with the areas identified, on the basis of the parameters calculated. The method includes determining an acceptability threshold of a specific defect for each type of defect identified. The method includes defining a corrective action for each area on the basis of a comparison between the acceptability threshold associated with the type of defect of the area, and a measurement of the surface measurements of the cylinder associated with the area. The method includes determining grinding parameters on the basis of the surface measurements of the cylinder, if the corrective action is a grinding operation to remove the defects.
