20080197120 | Method For Producing a Hole and Associated Device - Conventional methods for producing a hole in a component make use of special lasers with short laser pulse lengths. The aim of the invention is to reduce the time and money required for producing a hole. According to the inventive method, the laser pulse lengths are varied, short laser pulse lengths only being used in the area to be removed in which an influence on the throughflow or exhaust behavior is noticeable. This is, e.g., the inner surface of a diffuser of a hole that can be produced in a very precise manner using short laser pulse lengths. | 08-21-2008 |
20090001061 | Method For Producing a Hole - There are a multiplicity of methods of making through-holes. In particular in the production of a multiplicity of film-cooling holes, as in gas turbine blades or combustion chamber elements, small time advantages are also important when making a hole. The method according to the invention, to make the hole close to the final contour in each case in sections in a top and a bottom region in order to then produce the final contour with other laser parameters, achieves time advantages. | 01-01-2009 |
20090067998 | Component Having a Film Cooling Hole - Conventionally coated components with film cooling holes are known, comprising a diffuser, extending through the layers into the substrate. According to the invention, the component is embodied such that the whole diffuser is largely arranged in the layer. | 03-12-2009 |
20090135601 | Focusing apparatus with deflection for electromagnetic radiation - It is often not possible to use a rectilinear beam guidance for laser processing in the case of curved components, since the laser and the associated optics are often excessively large. Consequently, according to the invention, a focusing apparatus with beam deflection is proposed that reduces the relevant beam region by means of appropriate lenses and mirror such that it is possible to feed to relatively small locations. | 05-28-2009 |
