Ablative machining processes

Our focus is on the use and further development of ablative processes, with a particular emphasis on precision electrochemical machining (ECM) and laser material processing (LMB). Industrial and laboratory-scale plant technology allows for a wide range of research options to support the development of tomorrow's innovative products.

Trends

  • Electrochemical machining (ECM)
  • Laser structuring
  • Electrical discharge machining (EDM)

Reference projects

Efficient and resource-saving production of aviation gearboxes

Fraunhofer IWU, in cooperation with Liebherr-Aerospace and other partners, will make the design and manufacturing processes for aircraft gearboxes more resource-efficient and cost-effective. For materials such as the high-performance alloy steel 300M used in aviation, tailor-made PECM process chains are to be developed that will enable gearbox components to be manufactured economically even in the heat-treated state.

 

Flexible UV film injection molding system

In the past, surface functionalization was often based on chemical reactions and/or complete coating. These processes generate environmentally harmful by-products, which contradicts the “do no significant harm” principle of the European Green Deal. The BILASURF project aims to develop a new, less environmentally harmful process for the functionalization of complex 3D components.
