      The predecessor of HALNN Superhard material Co.,Ltd. is country Henan Superhard Material Institute. So the turning inserts and grinding inserts from halnn are all produced strictly,have a good quality.HALNN superhard company specialized in the production of CBN cutting tools/PCBN inserts/solid CBN inserts/hard turning tools and other super hard material products for turning/machining 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 hardened steel, Hi-Cr white cast iron etc,(such as:gear bearing,rolls/roller,ball screw,auto parts,brake disc,brale drum,etc) leading the world class level and enjoy a high reputation over the academia circles of super hard cutting tools. As a pioneer of Chinese super hard cutting tools, HALNN is the most famous brand on hard turning and high speed machining the hard material.
     Based on the State Key Laboratory of super hard materials and Henan University of Science and Technology, HALNN superhard company 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”.
History:
    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 CNY.
    At the end of 2003, BN-K1 CBN cutting tools used for machining high chromium white cast iron and chilled cast iron was promoted.This grade CBN inserts can both roughing and finishing the casting workpiece.
    In 2004, BN-H10 CBN cutting tools used for finishing harden steel was promoted, and has been in Chinese PCBN cutting tools area leading position.
    And the first company promoted the concept of roughing used “solid CBN inserts” in China, solid CBN inserts 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, BN-S10 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 turning harden steel with large allowance, which is the world breakthrough of CBN cutting tools industry.
    In 2007, BN-S30 solid CBN inserts professional used for roughing gray cast iron was promoted, breaking other countries 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 in China was developed by Halnn. So far, Halnn superhard won 25 national patents.
    In 2011, Halnn superhard material company was awarded one of the best company in cutting tools industry in China.
