CFK is one of the leading centers for high-precision wire, die-sinking and drill erosion and a professional partner for 3D printing in metal. We offer a high level of consulting and development expertise in these technologies. We machine demanding and safety-relevant components for a wide range of customers with the utmost precision. The range of unit weights covers 0.002 g to 4000 kg and workpiece sizes from μm to m. Our machine park with more than 45 machines enables high flexibility and therefore short delivery times – for single part and series production.
In EDM we have 33 years of experience, additive manufacturing (3D printing) we offer since 2004. For continuous further development, we cooperate with the RWTH Aachen and Fraunhofer Institute, among others. The successful work for our customers is based on the combination of highly qualified specialists with extensive know-how and modern machinery. Certified quality management and high-precision measurement technology ensure accuracies that meet the highest standards. This is appreciated by our partners from medical technology, aviation, the railroad industry, tool, mold and machine construction, energy technology, the electronics industry and R&D institutions.
Spark erosion is used for high-precision manufacturing, as all electrically conductive materials such as steel, aluminum, titanium, nickel-based alloys, hard metals, etc. can be machined to the nearest thousandth of a millimeter without mechanical stress.
As a manufacturing and machining specialist, CFK offers spark erosion with a precise fit and the highest machining quality as well as the fastest realization of even complex orders. Particularly in the case of small components, incisions and apertures with precise corners and angles can only be realized with EDM.
In manufacturing, the workpiece to be machined is processed in a non-conductive fluid. Die Verfahren werden unterteilt in funkenerosives Schneiden (Drahterodieren) und funkenerosives Senken (Senkerodieren). Drill EDM is a special application of die-sinking EDM (also called spark-erosive drilling or start-hole drilling).
Whereas in EDM cutting there is constantly an unworn tool in the form of a continuous wire electrode, in EDM countersinking the electrode creates the shape in the workpiece, with process-typical wear occurring on the electrode surfaces in engagement, which must be corrected to achieve a certain finished dimension.
The material-friendly production guarantees a particularly high surface quality and also reduces maintenance costs in your company due to its long service life. In this way, you can obtain high quality dimensional accuracy in a cost-efficient manner.
CFRP offers quality, time and cost advantages across the board.
More about spark erosion
Laser melting is a powder bed-based process that uses laser radiation to remelt metal powder layer by layer. With this manufacturing process, complex and near-contour three-dimensional geometries can be realized. With the geometric freedoms, this process complements previous conventional manufacturing methods.
In the laser melting process, a defined powder layer is fused with a laser. This is repeated layer by layer, and thus a component is produced using a 3D CAD file. With this manufacturing process, components can be produced with a density of up to 100% and still have the same mechanical characteristics as conventionally manufactured components. Various metallic alloys can be used as powder materials. For example, series materials such as various types of steel, titanium and aluminum alloys, as well as high-temperature resistant materials and copper alloys are used.
The laser melting process can also be used to directly image entire assemblies. However, these can also be improved with a topological optimization process in the area of weight savings, material savings as well as labor savings. As a result of these improvements, the new components are less expensive to manufacture, since they require less material and may even save on production steps.
Examples of applications for laser melting: prototype construction, individual implants (medical technology), small series production and lightweight construction.
