2. Advantages of PCBN Inserts

Description of PCBN material:

Cubic boron nitride is the second hardest material in the world invented successfully in 1957; the hardness of CBN’s single crystal is HV8000-9000 while the hardness of PCBN is HV 2500—5000, so its considerably better abrasive resistance than tungsten carbide and ceramics. With a higher ability of oxidation resistance within 1000℃, CBN will do not have any chemical reaction together with ferrous material in 1200--1300℃. So it is unique for CBN material dry cutting ferrous materials. The principal application areas for CBN cutting tools are hardened steels, cast irons and sintered irons as well as powder metallurgy components.

Features and Benefits of PCBN:

a. Excellent surface finish
b. High speed turning, high performance

c. More flexibility in machining
d. Less investment in machines
e. Dry Cutting, No required coolant

5. Common Application as follows:

CNC Indexable PCBN Inserts are mostly used for machining automotive parts, such as brake drum, cylinder, engine block, brake disc,ect.

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.
