The invention refers to a method and a press tool for manufacturing of a separating disk adapted to be included in a disk package of a centrifugal separator. The separating disk extends around an axis of rotation and has tapering shape with an inner surface and an outer surface along the axis of rotation. The separating disk is manufactured of a material and comprises a number of distance members in form of pressed protrusions extending away from the inner surface and/or outer surface. A blank of the material is pressed against the first tool part having a shape corresponding to the tapering shape of the pressed separating disk and comprises first form elements having a shape corresponding to the protrusions.
