4. Application

PCBN Inserts are mainly used for machining hardened steel and cast iron materials. Above cbn grade are mainly used for hard turning hardened steel, such as Gear Steel, Bearing Steel, Carbon tool steel, die steel, high-speed steel and so on.

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.
