The ability to efficiently process fibre-reinforced plastics (FRP) is one of the highly specialised disciplines in the machining industry. Although tools and machines are regularly pushed to their limits, there is all too often still room for improvement when it comes to the quality of such workpieces, the majority of which are machined via a dry process. As a process expert, Rhenus Lub knows how to overcome the hurdles standing in the way of cost-effective machining of composite materials such as carbon fibre-reinforced polymers (CFRP) and glass fibre-reinforced polymers (GFRP), and has an innovative solution to offer: using high-performance coolants that have been specially developed with these materials in mind. 

Enhanced workpiece quality and improved occupational health and safety

The new rhenus XY 190 FC and rhenus XT 46 FC special coolants help to machine composite materials much more efficiently than is the case with conventional dry machining. Your advantages at a glance:

  • Reduced tool wear
  • Enhanced component quality
  • Shorter production times thanks to higher cutting speed
  • Less rework necessary as delamination is reduced

The new rhenus special coolants also offer benefits when it comes to health and safety: Dry dust, which has the potential to cause cancer, is trapped optimally during production — a feature that ensures the highest level of acceptance among process owners and machine operators.

Expand your portfolio to include composite machining

The special feature: The innovative composition of our new special coolants now gives process owners who already use coolants but do not process fibre composite materials the ability to easily start working with this high-strength material. Existing machinery and tools, as well as existing wet machining processes can be retained for this purpose. Process owners benefit from a simple expansion to their service portfolio and the potential to secure additional business.

Products have impressed in comprehensive testing

Using these new special coolants, companies involved in production can rely on sophisticated, high-performance products from the very outset. After all, the rhenus XY 190 FC and rhenus XT 46 FC coolants have been developed by Rhenus Lub in collaboration with numerous reputable partners. The Research and Transfer Centre (FTZ) at the Westsächsische Hochschule Zwickau supported the project in terms of production suitability tests, and the German Aerospace Centre (DLR) in Braunschweig helped with material and compatibility tests.

All aspects of the new coolants’ performance were subjected to comprehensive field tests in collaboration with well-known customers from the automotive industry. “The field tests enabled us to impress our demanding test customers with remarkable results. For example, rhenus XT 46 FC helped carbon fibre-reinforced polymer machining to be carried out with a feed rate up to 60% higher than normal, producing four times as many parts”, explained Dr Hans Jürgen Schlindwein, Head of Coolant Research & Development and Quality Control at Rhenus Lub. “This performance makes our special coolants a future-proof alternative in the processing of carbon fibre-reinforced polymers and other composite materials”, continues Schlindwein.
