Key Technology: Laser caving

Particularly in the case of very hard, non conductive or high-melting materials (e.g. hastelloy, tungsten, molybdenum, hard metals, ceramic materials such as Si nitride and alumina), which are difficult to cut by conventional erosion procedures, new possibilities arise for three-dimensional shaping as a result of the employment of laser technology. The treatment of graphite electrodes is also very well possible by this procedure.
