Applications of Halnn CBN tools in Heavy duty Cutting
Category：News
PublishedDate：2019-05-27
Halnn, as the pioneer in the localization of China's superhard cutting tools. It is supported by the National Key Laboratory of
Superhard Materials and Henan University of Science and Technology.It has its own superhard tool R&D center, focusing on
the processing of brittle hard materials and difficult-to-cut materials. The research direction of CBN tools and high-grade
diamonds has unique advantages in the fields of “Turning instead of grinding”, ultra-high hardness and heavy-duty cutting,
high-speed machining, and difficult material cutting. At the same time, according to the innate resources of Henan Institute of
Superhard Materials, new CBN/PCD tools and other new materials tools are continuously introduced in 3C industry, aerospace
and nuclear energy military fields. Users cover China, Taiwan, Germany, Italy, the United States, South Korea, Japan and
many other countries and regions.
