Method and a device for manufacturing a stator component or rotor component

摘要

Method and arrangement for manufacturing a disk-shaped or annular stator component or rotor component with a plurality of blades arranged one after another in a path extending around the component and a cover (15) arranged outside the blades in the radial direction and in contact therewith. According to the method, at least a portion (11) of a first set of channels (12) is spark-eroded simultaneously out of a disk-shaped or annular workpiece (2) intended for forming the component at a distance from the edge (14) of the workpiece in the radial direction, which channels (12) are intended to delimit the blades in the circumferential direction of the workpiece.
