4. Typical Application Case with BN-H11 PCBN Inserts

BN-H11 PCBN Inserts finish machining GCr15 powder metallurgy bearings
Machining Condition: Cotinuous finish turning GCr15 Metallurgy Bearings,HRC62 Selected Insert: BN-H11 DNGA150404 Cutting Condition: ap=2.5 mm, Fr=0.12mm/r,Vc=140m/min
Insert material	Cutting Speed	Lifetime	Roughness
Halnn BN-H11 PCBN Inserts	140m/min	12 pcs/blade	Ra0.8
Other PCBN Inserts	140m/min	10 pcs/blade	Ra0.8

We can see that, with Halnn BN-H11 PCBN Inserts, the life time can improve about 20% than other pcbn inserts, and can confirm the surface roughness at the same time.

Zhengzhou Halnn Superhard Materials Co., Ltd is a high-tech enterprise specializing in the production of ultra-hardened tools, and the leader of professional hard material processing tools in China and the first to research new cutting tools specific for gray cast iron, kinds of wear-resistant steel/cast steel, hardened steel materials.
