The Process Characters of CBN Inserts
1. Suit for machining high hardness materials
CBN Inserts and PCD Tools are both called ultra-hard cutting tools because of their high hardness, and cbn inserts are mainly suitable for machining high hardness ferrous metal, and the workpiece hardness can be above HRC45. For example, Halnn BN-K1 
solid cbn insert can be used for machining high hardness materials which will arrive HRC79. And for these workpiece which hardness is below HRC45, we can’t choose this type insert.
2. Suit for roughing with large working allowance.
Solid CBN Inserts can be used for roughing with large working allowance, the cutting depth can arrive 8mm, and the machining efficiency will be improved several times.
3. High Cutting Speed
It can realize high cutting speed because its excellent advantages, the cutting speed can arrive 1500m/min, when machining gray cast iron parts with cbn inserts, it can obtain good surface roughness.
4. Dry Cutting
CBN Inserts have good red hardness, if add cutting fluid, the cutting tools will be easily chipping. So CBN inserts are usually used with dry cutting type, it not only environmental, but also save the costs.
