4. Typical Application ~ BN-H21 PCBN Tools For Interrupt Turning Gears

BN-H21 PCBN Tools heavy Interrupt turning Gears End Surface
Machining Condition: Heavy Interrupt Turning Gears Material: 20CrMnTi Gears, HRC58-62 Selected Insert: BN-H21 WNGA080404 Cutting Condition: Fr=0.1mm/r,Vc=117m/min, ap=0.15mm
Insert material	Lifetime	Failure Mode
Halnn BN-H21 PCBN Tools	600 pcs	Flank Wear
Other PCBN Inserts	100 pcs	Fracture

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

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.

The predecessor of Halnn Superhard Material Co.,Ltd is Henan Superhard Material Institute which is the earliest to make research on processing the brittle and hard materials with cubic boron nitride tools and High-Grade Diamond Tools. As the pioneer of Industry tools in China, Halnn adhere to the initial business philosophy of "Not seeking large and complete, only insist high-precision and professional". With more than 10 years experience, Halnn has researched one by one new materials grade, new technology and become the most famous cutting tools brand in superhard cutting tools industry.
