Monitoring the aging and performance of cooling liquids used in machining processes

Microbubbles and foaming behavior of fresh and used cooling liquids

In many areas of industrial manufacturing, liquid cooling is essential to ensure the machining process, the quality of produced parts, and the lifetime of machines.  Among other things, those liquids are designed to have maximum air release properties and minimum foamability. However, during usage foam formation increases, resulting in a reduced cooling efficiency.

The application report presented here contains a foam study on fresh and used samples of two different cooling liquids, carried out at the KRÜSS Applications & Science Center. We found a measurement procedure which finally facilitated a reliable and highly reproducible way of monitoring the loss of quality due to aging.
