How the Performance of Diamond Tools in Glass Grinding Can Be Influenced by Optimising the Coolant System

Dr. Michael Emonds and Dr. Joachim Esser, Dipl.Ing. Stefan Hambücker

Today coolants are used in the automotive
industry for pre-processing of automotive glass
(e.g. grinding and drilling of automotive sidelite
glass, mirrors).
This paper will show you that the glass grinding
process can be improved by choosing an
appropiate coolant and by optimising its
concentration. It will also discuss the influence of
the coolant on the diamond wear and the
roughness of the glass surface. In a research
project together with the „Fraunhofer Institut für
Produktionstechnologie IPT, Aachen“ we could
show that when grinding floatglass with a specific
diamond tool the feed rate could be increased by
the use of coolant AC 6261 up to 0,6 mm/min.
Using only water as a coolant limited the feed rate
to less than 0,2 mm/min.
