1. A method for manufacturing a separating disk adapted to be included in a disk package of a centrifuge rotor of a centrifugal separator,
wherein the separating disk extends around an axis (x) of rotation and has a tapering shape with an inner surface and an outer surface along the axis (x) of rotation, wherein the separating disk is manufactured of at least a material and wherein the separating disk comprises a number of distance members in the form of pressed protrusions extending away from at least one of the inner surface and/or the outer surface, wherein the method comprises a press step, which comprises pressing of a blank of the material against a first tool part, which has a shape corresponding to the tapering shape of the pressed separating disk and comprises first form elements having a shape corresponding to the protrusions, the press step further comprises: a first part step, where the blank by means of a second tool part is pressed in a direction towards the first tool part, a second part step performed after the first part step, the second part step comprising supplying a pressurized liquid between the blank and the second tool part and pressing, via the pressurized liquid, the blank into abutment against the first tool part; the pressurized liquid is provided through the second tool part; and the pressing, via the pressurized liquid, the blank into abutment against the first tool part of the second part step further comprises pressing the blank from an intermediate shape to a final shape. |
