Method for machining curved cooling passages in turbine blades and turbine blade having cooling passages

摘要

A method for introducing a curved cooling passage (20) in a gas turbine component, in particular a shovel (10), by means of an electrode (2), wherein an electrode (2) is used in the form of a helix, and the electrode (2) about its central axis of rotation (R) is rotatably driven; and coolable blade (10) for a gas turbine component having a helical cooling conduit (20).
