In 2002, Henan Superhard Materials Research Institute was established, made CBN cutting tools and high grade diamond as the main research direction. There are 2 Ph.D, 3 Professors, 5 Associate Professors, 12 R&D Doctor and Masters, and we also have cubic pressing machine and laser thermal conductivity meter and other large-scale equipment, with a total value more than 18 million RMB.

In 2003, we undertook the national key project of “Production-Study-Research”, and researched BN-K1 solid cbn grade specific for Hi-Cr white cast iron, chilled cast iron, which hardness and toughness is higher than ceramic cutters, and eet off a technology revolution in high hardness cast iron and other abrasive casting industry.

In 2004, we launched BN-H10 PCBN Grade, specific for finish turning hardened steel, and always in the leading position in Chinese brazing pcbn industry, and began to cooperated with the enterprise with the form of transfer technology, and make great contribution for our superhard materials industries.

In 2005,we undertaken national new materials project of “Tackling key problems of CBN Product”, researched BN-S20 Solid CBN Grade, specific for rough machining and interrupt cutting hard steel, and make it possible that cbn inserts can be used for interrupt turning hardened steel with large allowance, which is one of the world breakthrough in cbn insert industry.

In 2006,we created superhard tool marketing center and non-standard tool Division. Same year, we researched BN-K1 solid cbn insert for rough machining high chromium abrasive wear resistant cast iron , which got customers’ approval from all over the world, and our products have been sold Europe, America, East Asia, ect.

In 2009, we researched BN-K20 and BN-H20 Brazing PCBN indexable CNC Insert, which were widely used in interrupt cutting cast iron and hard steel.

In 2010, we researched the first GEM diamond with 1.7 gram in China, and also began to research other tools, and researched high grade pcd cutting tools and other diamond tools. So far, we total have 25 national patents.

In 2010, we were voted as the top-ten enterprise in Zhengzhou foreign exchange earning export.

In 2013,we launched BN-H21 PCBN Insert, and by that time, we have made the whole solutions on “turning instead of grinding”.

In 2015, we launched new cbn materials BNK30 for high speed cutting field, and have been exported to Europe, Japan, South Korea and other developed countries depending on the excellent abrasive resistance and stability.
