Manufacturing method for parts exposed to a gas flow

摘要

The disk (1) with integrated blades (a blisk) is produced by machining the appropriate 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 the direction of flow of a chemical used for the later polishing. A particular effective removal of irregularities is facilitated. The direction of feeding during the machining process is identical with the axis of the machining tool (4).
