The method uses electrical discharge machining to form, onto a disc (8) belonging to a stator (11) of a turbine pump, radial blades (12) joined to the disc at both ends and separated by very narrow channels (13). To form the blades, a workpiece (2) is exposed to a tool (1) having a circular edge (4)

The method uses electrical discharge machining to form, onto a disc (8) belonging to a stator (11) of a turbine pump, radial blades (12) joined to the disc at both ends and separated by very narrow channels (13). To form the blades, a workpiece (2) is exposed to a tool (1) having a circular edge (4) whose radius corresponds with an external radius of the blades. The tool is provided along its edge with at least one tongue-shaped elongated member (5) joined at one end to the tool plate (3) and extending along said edge (4) in an inclined plane. Due to a relative combined rotation and translation motion between the tool and the workpiece, at least one channel (13) with shape, size and inclination corresponding with those of the tongue element (7) is produced in the workpiece.
