High performance ceramics are characterized by their high wear resistance and temperature stability. Thus, they gain in importance in different fields of application. The machining of high performance ceramics after sintering can be classified as challenging as a result of its brittle, high-tensile material behavior. Until now, precise machining of these materials could only be implemented in a limited field due to the process limits of conventional manufacturing methods. New techniques for filigree finishing of silicate, oxide, and non-oxide ceramics changing the microscopic as well as the macroscopic surface conditions, are prioritized in the research project. The engineering of the system with reduced diameter of an abrasive waterjet based on the injector principle enables the precise machining of these difficult-to-cut materials. Due to exceedingly low process forces, this method qualifies for manufacturing different surface structures and surface forms on brittle workpiece materials. This technology allows the process reliable inserting of smallest geometries, that are not or on a limited basis moldable during the sintering process.
