Method for producing a rotating disk for a turbomachine

A method for producing a rotating disk for a turbomachine, the method comprising,

• providing a disk,
• initially forming first blade root uptakes at a plurality of first circumferential positions about said disk, by introducing first profile grooves in the disk at said plurality of respective first circumferential positions, each of the first profile grooves having respective inner wall surfaces, and
• subsequently forming second blade root uptakes by introducing second profile grooves in the disk at a plurality of second circumferential positions about said disk, each of said second circumferential positions located circumferentially between two of the first profile grooves,
• wherein, at least one second profile groove of the second profile grooves is located circumferentially between every two of the first profile grooves,
• wherein, during the formation of each second profile groove of the second profile grooves, each first profile groove of the first profile grooves adjacent the second profile groove being formed are supported by an insert,
• wherein a land remaining between one first profile groove of the first profile grooves and the at least one second profile groove, that is a circumferentially adjacent to the one first profile groove, has a width W taken in a circumferential direction and the one first profile groove and the at least one second profile groove each have a radially taken depth D, and
• wherein D/W ≥2.5.
