Vor allem der Boom bei Großflugzeugen krempelt die Materialwelt um: Plötzlich gilt es im großen Maßstab und mit hoher Produktivität Titan, Nickelbasislegierungen, höchstfeste Stähle und Kohlenfaserkunststoffe (CFK) zu zerspanen. Konventionelle Kühlschmierkonzepte stoßen hier oft an ihre physikalischen Grenzen. Das Potenzial kryogener Kühlung im Vergleich zu konventionellen Verfahren nahm Hendrik Abrahams, Wissenschaftler am Institut für Spanende Fertigung (ISF) an der Technischen Universität Dortmund unter die Lupe.
Herr Abrahams, im Kommen ist aktuell eine Vielzahl von neuen Werkstoffen. Wann und wie kam hier die kryogene Technik, also das Kühlen mit technischen Gasen, ins Spiel?
