1. Description:
PCBN Blanks can be divided into two kinds: Carbide backed PCBN and Solid PCBN. The former is composed of carbide substrate and polycrystalline CBN layer, and the latter is overall polycrystalline CBN.
2. Specification:
| CBN Content | Type | Property | Application |
| 90% | Solid PCBN Carbide backed PCBN | Excellent wear resistance and anti-chipping, better impact resistance | Gray cast iron, powder metallurgy metals |
| 70% | Solid PCBN Carbide backed PCBN | Good wear resistance and impact resistance, better chemical stability | Hardened steel,Mould steel, |
| 50% | Solid PCBN Carbide backed PCBN | Excellent chemical stability and good thermal stability | Chilled steel
|
3. Application:
PCBN Blanks are suitable for continuous and interrupted cutting of ferrous metal materials, such as various chilled steel, cast iron and powdered metal.
