2. Brazed PCBN Inserts for turning hardened steel Cutting Condition

3.Common Models of PCBN Inserts VNGA/CNGA

This type brazed pcbn inserts are made with 4 cutting edges, wich can help the customers reduce the costs, the common models are as follow:

4. Typical Application Case with BN-H20 PCBN Inserts

BN-H20 PCBN Inserts finish turning synchronizer gear sleeve
Machining Condition: Cotinuous finish turning Gear Steel,HRC58-63 Selected Insert: BN-H20 VNGA160404 Cutting Condition: ap=0.15mm, Fr=0.1mm/r,Vc=170m/min
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.
