Evaluation of different methods of cooling-lubrication in cylindrical grinding of advanced ceramic dip
(Materials Research, 2014-10-01) [Artigo]
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 ...
Grinding of hardened steels using optimized cooling
(Ingeniare, 2008-06-01) [Artigo]
Grinding - the final machining process of a workpiece - requires large amounts of cutting fluids for the lubrication, cooling and removal of chips. These fluids are highly aggressive to the environment. With the technological ...
The cutting time with abrasive discs can be reduced by the control of the cutting speed
(Technical Paper - Society of Manufacturing Engineers. MR, 1997-12-01) [Artigo]
This paper presents an experimental study on the life of abrasive discs in cut-off type operations with two conditions of cutting speed. The cutting time is shown with a comparative analysis of the cutting speed.
Estudo do comportamento de discos abrasivos, em operações do tipo Cut-off por mergulho basculante, submetidos à diversas condições de corte sem lubrificação
