摘要:
In a manufacturing method for closed vane wheels having vanes (2, 2a) between which vane channels (3) are formed which have a predefined shape, openings for the vane channels are prepared by means of a program-controlled chip forming cutting apparatus in a blank in a chip forming cutting process. In the manufacturing method, in a further workstep, electrodes (11) of an apparatus for spark erosion or for electrochemical stock removal are additionally introduced into the openings and a part of the predefined shape of the vane channel (3) is manufactured by means of spark erosion or by means of electrochemical stock removal.
