The predecessor of HALNN is Henan Super hard Material Institute. HALNN is a high-tech enterprise that specialized in the production of
CBN cutting tools and other super hard material products, and the
first R&D company focus on cutting tools for gray cast iron,
all kinds of wear resistant cast iron/cast steel, harden steel
materials in this industry. The main products PCBN cutting tools
and solid CBN cutting tools have obtained several practical
patents, especially in interrupted cutting of harden steel, Hi-Cr
white cast iron etc, leading the world class level and enjoy a high
reputation over the academia circles of super hard cutting tools.
As a pioneer of domestic super hard cutting tools, HALNN is the most famous brand on hard material processing and high speed
Based on the State Key Laboratory of super hard materials and Henan
University of Science and Technology, HALNN established its own R&D Center of super hard cutting tools, has
undertaken and completed the national key project of
“production-study-research” and the project of science and
technology research on CBN products, and is implementing the
national demonstration projects& the plan projects of “gem
grade diamond products”.
In 2002, HENAN Super Hard Research Institute was established, CBN cutting tools and high grade diamond as the
main research direction. There has 2 Ph.D, 3 professors, 5
associate professors, 12 R&D Doctor and master, owns cubic
pressing machine and laser thermal conductivity meter and other
large-scale equipment, with a total value of more than 18 million
At the end of 2013, HN10 CBN cutting tools used for machining high
chromium white cast iron and chilled cast iron was promoted.
In 2004, HNC 10 CBN cutting tools used for finishing harden steel
was promoted, and has been in the domestic PCBN cutting tools area
leading position. In domestic first promoted the concept of
roughing used “solid CBN inserts”, the product in roughing high
chromium white cast iron rough areas made the industry unanimously
approved. And as CBN cutting tool technology transfer and
enterprise combining research cooperation mode, has made tremendous
contributions for our super hard materials industry.
In 2005, HN 20 CBN cutting tools used for harden steel interrupted
cutting was promoted, breaking the myth of CBN cutting tools
couldn’t be used for heavy interrupted large allowance turning
harden steel, which is the world breakthrough of CBN cutting tools
In 2007, HN30 solid CBN inserts used for gray cast iron was
promoted, breaking the foreign CBN cutting tools in the field of
high speed machining gray cast iron monopoly.
In 2010, the first 1.7 carats Blue gem grade diamond was developed.
So far, won 25 national patents.
In 2011, began to independent R & D and production of high-end
polycrystalline diamond (PCD) cutting tools.
As a professional hard materials processing tool leader Halnn
adheres adhering to the "dedication, innovation, efficiency,
cooperation," business philosophy, unity of spirit, the spirit of
enterprise and self-reliance, respect for science and technology,
to create value, collaborative development, and create a respected
brand in the world.
