We work on glass, glass ceramic and ceramic(s) for technical applications on computer-controlled machine tools and robots. Shapes, which consist of straight lines, radii or arbitrary forms and run into one another, can be manufactured with highest accuracy also in 3 D-technology. Contour-controlled shaping arbitrary radii: all mathematically recordable and digitized forms Inside contours: Drillings, paragraphs, long holes, bags, slots and lowerings in arbitrary dimensions, edges CNC shaping is the beginning of a glass refinement process. Further processing and modification of optical characteristics or individual impressions will be offered one-stop. BERLINER GLAS offers the possibility for the direct data transfer from CAD systems (by disk/E-Mail) for the most common file formats (DXF, IGES, VDA). In the context of the CNC-shaping we offer the following edge forms: Raw cut or sawed glass has very sharp edges which can be further processed. There are various suitable edge work options depending on the requirements .The possibilities are listed below. BERLINER GLAS offers: Glass is scribed with a diamond or hard metal wheel and then broken on the scribe. The unworked broken edges are sharp and can chip easily. Edge Type Function (reduced risk of injury) Design Costs Cut edges Glass is scribed with a diamond or hard metal wheel and then broken on the scribe.. Sharp. - - Seamed edges Reduced risk of injury. + - Ground edge w’ seam The broken area is matt ground. Additionally the edge may be seamed as described in 2. above. + + C-Edge The broken area is ground to form a C. It has a matt finish. + ++ Bevelled Edges The edge is ground to form a bevel. In general a bevel is larger than a seam and may have any desired angle between 20 ° and 70 °. + ++ Polished edge Polished for transparency and deesign + +++
