Abstract
Four different types of commercially available ceramic tools - Al2O3, Al2O3:TiC, Al2O3:SiC(w) and a sialon - have been used to turn heat treated SG iron at speeds between 150 and 450 m min-1. The irons were either hardened by an austempering treatment giving a hardness of approximately 350 Hv, or softened to a hardness of approximately 180 Hv by an annealing treatment.
Wear on the flank of the tools was the most common cause of tool rejection although tool fracture occurred when machining the austempered iron at the highest speed.
Sialon tools suffered rapid wear and the Al2O3:SiC. significantly underperformed the other alumina based tools under most conditions. Fracture damage on the tools' cutting edge and chemical interaction between tool and workpiece have been identified as important wear mechanisms in controlling tool life.
