| 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. |
