4. Typical Application Case with BN-H05 PCBN Inserts
| BN-H05 CNGA120408 PCBN Inserts Continuous turning 20CrMnTi Gears |
Machining Condition:Continuous turning gears Material: 20CrMnTi Gears, HRC58-62 Selected Insert: BN-H05 CNGA120408 Cutting Condition: ap=0.1mm, Fr=0.1mm/r, Vc=180m/min, Dry Cutting |  |
Insert material | Roughness | Life Time |
| Halnn BN-H05 PCBN Inserts | ≤ Ra0.8 | 800 pcs |
Other Europe PCBN Inserts | Ra1.0 | 550 pcs |
From above application, we can see that for continuous turning
process , with Halnn BN-H05 PCBN Inserts, the tool life improved
30%. And the roughness also improved.
5. Other Application of BN-H05 PCBN Inserts
BN-H05 PCBN Inserts are researched specific for machining hardened
steel, such as bearing steel, gear steel, high strength steel, it
can be used for only continuous turning , normally we used for
machining hardened steel component, such as gears, bearing. When
the inner bore doesn't have keyway, it will only belong to
continuous turning condition. At this time, We can choose BN-H05
PCBN inserts. The following is some other typical application for
machining hardened steel with PCBN Inserts:
