About Zirconia Ceramic End mill


Diamond coating end mill processing is difficult, and the diamond coating costs even more, 

resulting in a very expensive overall manufacturing cost. 


Ceramic end mill doesn't need diamond coating, saves a large amount of processing cost and raw materials,

can be processed at high speed even in a high-temperature environment, realize high-efficiency rough machining of the tungsten steel

end mill and is a new choice for high-efficiency processing.


The application of ceramic cutter end mill  to the processing of graphite

Due to the lower affinity of the ceramic material and the graphite, the sharp and smooth edge of the end mill

can improve the surface finish of the product.

Zirconia ceramic's processing is easier than tungsten steel, therefore ceramic end mill have varieties of types.

At the same time,ceramic end mill not only have high hardness and excellent bending strength,

but also have long service life.

End mill parameter: white Zirconia(D10 rough machining、D4 R0.2 Semi-finishing、R0.5 and R1.5 precision work).

All tests are qualified, the service life is up to 10 hours, the processing surface is bright, and there is no surface scratch caused by the diamond end mill.


Ceramic end mill can be reworked after use. Because of the characteristics of the ceramic material, the service life after the repair is not affected by the 

repairing tool, and the service life of the new end mill is the same.

 

Conclusion:

Surface finish quality:ZrO2>Tungsten steel+ diamond coat= Si3N4+Diamond coat>Si3N4 Ceramic>cermet

Abrasion loss:ZrO2<Tungsten steel+ diamond coat = Si3N4+ diamond coat<Tungsten steel<Si3N4<cermet

Cost:ZrO2<Tungsten steel+ diamond coat= Si3N4+ diamond coat

Zirconia ceramic is more suitable for high precision and high life processing of graphite mould.
