Design of an eco-friendly coolant for grinding using anti-bacterial additive
Synthetic coolants are important to meet required productivities in grinding. The disposal of synthetic coolants is a difficult issue since it poses environmental hazards. There have been many attempts to either minimise the use of coolants or to develop new compositions for eco-friendly coolants. The present paper discusses the possibility of using anti-bacterial additives to develop eco-friendly coolants based on water. The performance of the new coolant is studied in cylindrical grinding applications and shown to be on par with, or better than, that of synthetic coolants.
