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:

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.
