Publikováno v: Materials Research, Vol 17, Iss 5, Pp 1201-1212 (2014)

The current work presents a study of alternative methods of cooling-lubrication for the external plunge grinding of advanced ceramics using diamond wheels. These two alternative methods, which are intended to reduce cutting fluid expenses, are common
