The system has an upper brooch (11) centered in a hole (18), and a stud (12) containing a floating screw (14), where the stud is assembled with a closing plate (13). A lower brooch (15) is passed through another hole (19) superimposed at the former hole. The lower brooch is driven in cooperation with the floating screw, where the brooches have form for ensuring centering of the brooches in the holes. Independent claims are also included for the following: (1) a device for controlling concentricity of cylindrical hole axles comprising a measuring apparatus (2) a method for controlling concentricity of cylindrical hole axles (3) a two-dimensional (2D) control model. |
