Etude de l'usure des outils agglomérés utilisés en polissage et doucissage de précision

Abstract

Conventional lapping and polishing technologies have been achieved by free abrasive grains. This method remains the most reliable for the realization of very high quality surface; nevertheless it presents a significant loss of time and abrasive grains. Lapping and polishing by related abrasive grains was able to prove these by producing better surfaces compared to polishing with free abrasive grains. The objective of this work is the realization of agglomerated tools based on abrasive grains of alumina and cerium oxide with different parameters namely the nature of the binder, the pressure of compaction, which can influence the surface quality obtained. In addition, the wear behavior of the pellets and the influence of the processing conditions have been invested to highlight their effect on the finishing processes.
