13mm 19mm 30mm PCBN blanks for CNC Turning inserts PCBN inserts

 

PCBN (polycrystalline cubic boron nitride ) is new super hard material, which is a composite of CBN(cubic boron nitride) under the high voltage and high temperature. It has the same hardness, thermal stability, thermal conductivity and good impact resistance as CBN, it is the most ideal cutting tool for machining ferrous metal, as it has high toughness, abrasion resistance and heat resistance characteristics.

 

The standard shape of RJ PCBN Cutting Tool Blanks is round. Other shapes, such as rectangle, triangle, square, semi-circle and so on, can also be customized per customers' requirements.

 

RJ PCBN Cutting Tool Blanks consist of fine CBN grains sintered under ultra-high pressure and ultra-high temperature. Combining the strengths of hardness, thermal stability, thermal conductivity, and strong impact resistance ability characteristic of CBN, they are ideal for cutting tools for the machining of ferrous metal and alloy, all with high productive efficiency, high machining precision, and good surface quality.

 

RJ CBN Cutting Tools Blanks are composed by BN and PCBN two series:

 

BN characteristics:
1. Solid CBN
2. Good wear resistance
3. Two sides can be used as edges
4. High thermal resistance
5. Excellent fracture resistance

 

BN application:
1. High Speed Turning and milling of gray cast iron
2. Turning of chilled iron, nickel-based iron and ductile iron

 

PCBN characteristics:
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. Good consistency of processing.

 

PCBN application:
1. Turning of cast iron.
2. Powdered metals.
3. Exotic materials and heat resistant alloys.
4. High speed milling of gray cast iron.
