The present invention is directed to a method for producing a rotating disk for a turbomachine, forming blade root uptakes on a plurality of circumferential positions, for which, in each case, an axially extending profile groove that is bounded circumferentially by inner wall surfaces of the rotating disk is introduced on a respective circumferential position, in which production method, initially first profile grooves are introduced in a disk on first circumferential positions, and subsequently, a second profile groove is introduced in the disk on a second circumferential position located circumferentially between the first profile grooves.
