    Abstract: The present invention relates to an apparatus for machining holes, especially to machine holes in a surface of a coated gas turbine airfoil, which apparatus comprises a laser device for laser drilling and an electrode for electrical discharge machining. Further the invention relates to a method to machine a hole into a coated surface with an apparatus of the incipiently mentioned type. Known methods make use of a machine with separate machine heads for laser drilling and electrical discharge machining. By combining these two devices in one machine head the invention gives the possibility to save time and obtain very accurate results.

    Abstract: A method of masking cooling holes of a turbine component, in particular a turbine blade or vane, for a coating process is provided. The component includes an external surface to be coated, at least one internal cavity having an opening towards the outside of the component, and cooling holes extending from the at least one internal cavity to the external surface. The method comprises the steps of: filling the cooling holes with a masking material and hardening the masking material. The masking material, water, is used to fill in the cooling holes. The hardening is done by freezing the water to water ice. A method of coating an external surface of a turbine component and a device for use in a masking process for masking cooling holes in a turbine component are also provided.
