It can be concluded that CC620 (pure alumina with the addition of ZrO2) demonstrates superior(700, 1000 m/min), CC650 (mixed alumina, Al2O3 + TiC) is recommended. Analysis of these results 1000 m/min), CC650 (mixed alumina, Al2O3 + TiC) is recommended. Analysis of these results wascarried out through chip study and XPS.
