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:
