Abstract
The invention pertains to a method for manufacturing a rotary anode assembly for an X-ray tube. According to the invention, a base element made of graphite is joined in a first step as a blank with excess dimensions to a shaft by material bonding. Then the further processing of the rotary anode assembly takes place by mechanical machining to nearly final-form dimensions and by application of the focal track coating, wherein the axis of rotation of the shaft is utilized as the reference for the performance of the mechanical machining.
