Device and method for removing coating material from openings in a part

A process for coating a component, wherein the component comprises a first region and a second region, wherein the first region comprises at least one cooling fluid opening comprising an adjoining cooling fluid channel, and wherein the first region is to be coated with a coating material which is not to be applied in the second region, the process comprising the following steps:

• A) introducing the component into a first apparatus suitable for:
• detecting at least one reference point in the second region of the component;
• and determining a position of at least one cooling fluid opening in the first region of the component,
• B) detecting the at least one reference point in the second region of the component and determining the position of the at least one cooling fluid opening in the first region of the component by means of the first apparatus,
• C) optionally removing coating material which is present in the first region of the component,
• D) optionally repairing at least one occurrence of damage in the first region of the component,
• E) applying the coating material in the first region of the component, wherein the at least one cooling fluid opening is at least partly closed by the coating material,
• F) detecting the at least one reference point in the uncoated second region of the component and removing the coating material in the first region of the at least one cooling fluid opening by means of a second apparatus,
• wherein the second apparatus comprises at least one detection device, at least one holding device, and at least one instrument for removing coating material in the first region of cooling fluid openings,
• wherein the at least one holding device is suitable for providing direct or indirect, detachable fastening of the second region of the component to the second apparatus,
• wherein the at least one detection device is suitable for detecting the at least one reference point in the second region in order to determine the position of the at least one reference point and/or to adapt a position of the component on the basis of the at least one reference point,
• wherein the at least one instrument for removing the coating material in the first region of the cooling fluid openings is suitable for removing the coating material in a targeted manner from the cooling fluid openings on the basis of the position of the component determined by means of the at least one detection device and/or an adapted position of the component in order to restore functionality of the cooling fluid channels, and
• wherein the detecting of the at least one reference point is carried out by touching the at least one reference point.
