Modular laser integration into machine tools

In order to improve the flexibility, speed and quality of the manufacturing of parts and components with laser-treated surface areas, the Fraunhofer IPT has developed a new technology platform from which to integrate laser modules into machine tools. In the course of this paper, this new concept of modular laser integration is described, using the example of a lathe/milling machine that has been equipped with two different laser tools for hardening and for deposition welding. The hybrid machine tool is the first of its kind not to need component reclamping between the fullyautomated turning, milling, drilling, laser hardening and laser deposition welding operations. Simultaneous 4-axis processes are possible with both the laser processes and the cutting processes. Some machining results are discussed. The paper concludes with a short outlook on the economic potential of the new laser integration concept.
