We supply our customers with sputtering targets and a wide variety of individual quartz-glass structural components. In machining, we draw on our vast experience – and with our highly flexible machinery are able to offer all relevant machining techniques. This enables us to conduct highly precise cutting work by means of ID sawing, bandsawing, peripheral (OD) sawing and rotary sawing, working in a way that is gentle on the material and minimising kerf loss. In addition, we also shape quartz glass for specific applications using a wide range of grinding techniques, such as surface or plane grinding, external cylindrical grinding, internal cylindrical grinding, precision surface grinding and creep-feed or profile grinding. In order to implement even the most sophisticated geometries for you, we use machines and tools specially adapted to the material. For example, we use 3- and 4-axis CNC machining and carry out precise drilling work.
