Efficient laser processing

Hybrid manufacturing machines and laser modules

The Fraunhofer IPT has many years of experience in the field of laser system integration. In previous projects, conventional milling, turning and pressing machines have been successfully converted into hybrid machine tools. Likewise, the development of laser modules that can upgrade existing machines to multifunction machines has been achieved. Such systems are not only suitable for local heating or hybrid processes, but also for additive manufacturing in combination with machining processes. We design the laser integration in a targeted manner so that only a small amount of intervention in the architecture of the base machine is required. In addition, we use standardized components to make the machine easy to retrofit, maintain and operate without restricting the original machine functionality.

MIRA technology platform

MIRA combines a spacious work area with a highly maneuverable robotic arm – ideal for the precise machining of large components up to 2.5 x 4 meters, such as rotor blades for hydroelectric power plants. Fraunhofer IPT has integrated various processes into the MIRA cell, including laser structuring as well as laser and arc deposition welding. Equipped with this technology, we offer contract research for the fast, precise, and cost-effective processing of metal and even glass components – with maximum design freedom.

hy-PRESS modular press extensions

The hy-PRESS module permits components made of high-strength steels with high component complexity and demanding edge quality to be produced with low tool wear. A laser beam heats the material locally at the points to be machined. Localized heating improves formability and cutability for the duration of processing. The system which has been retro-fitted with hy-PRESS thus significantly improves conventional sheet metal processing in bending, stamping, deep drawing, cutting and flange forming operations conducted on high-strength steels.

LaserTurn lathe

By modifying the tool revolver in the "LaserTurn" lathe developed by Fraunhofer IPT, the laser beam can be guided inside the revolver to the tool stations. The beam is coupled with exchangeable, beam shaping tools and performs the required component processing step.

5-axis milling center

We integrate an optical laser spindle instead of the conventional milling spindle in a 5-axis milling machine. As a result, we can use the machine for laser surface treatment of complex geometries and for additive manufacturing.
