Rotor realization process and X-ray tube rotor

The invention concerns a rotor realization process for X-ray tube, composed of an iron cylindrical core covered with a copper layer, characterized in that it consists in - excavating two grooves in the cylindrical core periphery, parallel to its directrix D and near its two ends with triangular profile - placing around the core a copper tube the diameter of which is approximately equal to the core diameter and of the same length -warping the copper tube along two grooves sinking respectively in the two core grooves, showing a triangular profile the sides of which are parallel and on contact with the iron core groove sides. It applies specially to radiology devices. 3 refs., 6 figs
