PCBN

PCBN does not react chemically with iron and is ideal for tools machining hard ferrous metal(HRC45-65)such as:high speed steel,bearing steel and cast iron etc.
PCBN is typically used to machine brake discs,engine blocks,engine cylinder liners,brake drums,flywheels,valve seats/guides,gears, mould and die parts etc.
PCBN tool�s predominance is:
1.Good weld based in the composite CBN layer and tungsten carbide base.
2.High abrasion resistance.
3.Good transversal rupture strength resistance.
4.Good chemic stability.
5.Uniform dimension precision.
6.Consistent Quality.
PCBN tool�s application is:
1.Turning of castiron.
2.Powdered metals.
3.Rare metals and heat resistant alloys.
4.High speed milling of gray castiron
