Machining Condition: Cotinuous finish turning Gear Steel,HRC58-63 Selected Insert: BN-H20 VNGA160404 | ![]() | ||
Insert material | Cutting Speed | Lifetime | Failure Mode |
Halnn BN-H20 PCBN Inserts | 170m/min | 350 pcs | Flank Wear |
Cermaic Inserts | 120m/min | 70 pcs | Fracture |
We can see that, with Halnn BN-H20 PCBN Inserts, the tool life improved about 5 times than other Ceramic Inserts, and the failure Mode is flank wear, however Ceramic inserts are fracture.
