Abstract: A multiple polishing head (10), especially suitable for working on stone materials to carry out roughing or surface finishing operations on the same and arranged to be combined with a robotic manipulator (20) with multiple degrees of freedom, comprises at least two electrospindles (24), to the front face of which as many tools or machining tools are combined. The polishing head (10) is connected to the wrist (16) of the arm (14) of said manipulator by means of a flange (12), fixed to an inclined plane (18) defining the upper part of a frame (22). The electrospindles (24), preferably three, are connected to the lower face, consisting of a plate (26), of the frame base (22).

Abstract: 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.

Abstract: Method (100) for the classification of defects and running of the grinding of lamination cylinders comprising the following phases which consist in: a) identifying defect areas in a map illustrating a plurality of surface measurements of a cylinder; b) calculating, for each defect area identified, a plurality of typical parameters; c) identifying a type of defect associated with said defect areas identified, on the basis of said parameters calculated; d) determining (120) an acceptability threshold of the specific defect for each type of defect identified; e) defining (130) a corrective action for each defect area on the basis of the comparison between said acceptability threshold associated with the type of defect of said defect area, and a measurement of said plurality of surface measurements of the cylinder associate with said defect area; f) determining (140) grinding parameters on the basis of said surface measurements of said cylinder, if the corrective action defined in phase c) is a grinding operation
