4. Typical Application Case with BN-H21 PCBN Inserts

BN-H21 PCBN Inserts heavy turning Gears End Surface

Machining Condition: Heavy Interrupt Turning End Surface

Material: 20CrMnTi Gears, HRC58-62

Selected Insert: BN-H21 WNGA080404
Cutting Condition: ap=0.15mm, Fr=0.1mm/r,Vc=117m/min

Fracture

We can see that, with Halnn BN-H21 PCBN Inserts, the tool life improved about 6 times than other PCBN Inserts, and the failure Mode is flank wear, however other pcbn inserts are fracture.

5. Other Application of BN-H21 PCBN Inserts

BN-H21 PCBN Inserts are researched specific for heavy interrupt turning process, normally we used for machining hardened steel component, such as gears, bearing. When the component surface have many holes, it will appear interrupt turning condition, the insert will not easily chipping or fracture with BN-H21 PCBN Inserts. The following is some typical application which will use PCBN Inserts BN-H21 with heaby interrupt turning condition.
