Abstract: An apparatus for surface processing of cylindrical bodies including a work station (100) for rotatably supporting the cylindrical body (1), a laser emitter (600) movable along a main direction (X) parallel to the rotation axis (K) of the cylindrical body (1) and according to an auxiliary direction (Z) transverse to the main direction (X), a distance sensor (700) for detecting a control parameter relative to a distance of the sensor or the laser emitter (600), and a control unit (15) configured for commanding a movement of the laser emitter (600) and of the distance sensor (700) along said main direction (X), commanding the emission of a laser beam directed towards a surface of the cylindrical body (1), executing a correction procedure adapted to compensate for the eccentricity of the cylindrical body (1) with respect to said rotation axis (K).

Abstract: A lamination cylinder includes a surface structure, on which a plurality of craters is defined having a different geometry and a random distribution. Some of the craters are partially superimposed with respect to each other.

Abstract: A positioning of a spindle with micrometric forwarding control and tilting of its rotation axis includes a spindle shaft rotatingly supported inside rotatable supports, wherein the rotatable supports include two spherical elements having housings which are eccentric with respect to the rotation axis that join the centers of the spheres, and wherein the two spherical elements are positioned in a cylindrical housing having at least two parts, and wherein two rotation elements are connected to the two spherical elements and cause their independent rotation.

Abstract: 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.
