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.
