“…When turning BN free-machining steel, the tool life of the alumina TiC-based ceramic tool is about 10 h when the tool life criterion is set to VB = 0.3 mm. This tool life is about 15 times as long as that of a pure alumina ceramic tool and about twice as long as that of coated carbide tool (3) .…”

This study examined the wear characteristics of ceramic tools when turning BN free-machining steel based on AISI 1045. An experiment was conducted to investigate why the alumina TiC-based ceramic tool showed remarkably better cutting performance than a pure alumina ceramic tool. The tool flank temperature, cutting force, and element distribution on the wear part were investigated. The cutting force and tool flank temperature of the BN free-machining steel were lower than those of standard steel, and the alumina TiC-based ceramic tool allowed for a lower cutting force and tool flank temperature than the pure alumina ceramic tool. After cutting of the BN free-machining steel, on the rake face, a deposited layer containing Al and N was detected, and the amount of the deposited layer on the alumina TiC-based ceramic tool was more than that on the pure alumina ceramic tool. Therefore, using an alumina TiC-based ceramic tool suppresses the tool flank temperature and makes it easier for a protective nitride layer to stick on the wear part; as a result, it has a clearly superior tool wear resistance than an alumina ceramic tool.

“…Ceramic components are highly resistant to diffusion and oxidation [1] [3]. Increased fragility as compared for example to the cemented carbide is offset by the use of lower feed rates at higher cutting speeds [4]. Ceramic inserts should be used on machines with good geometric accuracy and high rigidity.…”
