摘要：The disk (1) with integrated blades (a blisk) is produced by machining theappropriate work-piece into a ring (2) with surrounding blades comprising gaps (5)between them. Grooves are created on its surface positioned in a right angle to thedirection of flow of a chemical used for the later polishing. A particular effective removalof irregularities is facilitated. The direction of feeding during the machining process isidentical with the axis of the machining tool (4).
