Nano Alumina/Nano Aluminium Oxide as Ceramic Cutting Tool

1.Different characteristics between Alumina and other tool materials are: a stable alumina chemical properties, excellent oxidation resistance, even if it is at the cutting edge and become red hot, it still can work for a long time. Alumina ceramic tool is particularly suitable for high-speed cutting and heating cutting. 

2.Due to poor wettability of alumina to the majority of metals, it is difficult to bond with the metal, in the cutting performance of low coefficient of friction, cutting force is small, easy to BUE and adhesive wear, so easy to get it working high light cleansing. 

3. Alumina is the most of all the tool material inactive, you can reduce the spread of the cutting tool wear, Al2O3 dissolution rate of iron than WC 4 to 5 times lower, thus alumina ceramic cutting tool wear when steel rate than the WC-based cemented carbide cutting tools as small as a few times to magnitude. 

4.The use of alumina ceramic tool suitable for high-speed cutting and high wear resistance characteristics of processed bulky. Alumina suitable for processing most metallic materials, especially suitable for cutting hardened steel or chilled cast iron, material used for these fine cars instead of grinding can achieve significant technical and economic benefits. Alumina at high temperature to maintain high hardness, the cutting speed up to 1300 m / min.

Currently the Alumina ceramic tool is mainly used for semi-finishing and fine cutting, fine cutting its accuracy and finish suitable for hard materials to car instead of grinding, and improve processing efficiency several times, processing costs can be reduced by more than half, so the alumina ceramic cutting tool is very popular.
