advantages. The present investigation is to evaluate the influence of MQL on chip formation mode and surface roughness in grinding AISI 1045 steel with CBN wheel at different level of process parameters. The result indicated that, MQL enables the reduction in surface roughness and more favorable chip formation mode compared to dry grinding.

A STUDY ON THE MINIMUM QUANTITY LUBRICATION IN …

Aug 09, 2013· MQL grinding has also been studied in Europe with similar conclusions regarding workpiece cooling (Brinksmeier et al. 1997). Although CBN wheels are widely used in industrial production, there is limited research in CBN MQL grinding (Silva et al. 2005). This research studies MQL grinding performance of the vitrified CBN wheel using soybean oil.
