The 12-inch wafer of a disc, polished by a "wafer thin grinding wheel", is as smooth as a mirror.Silicon chips engraved with integrated circuits are cut into chips after precise strokes by high-speed rotating "silicon chip scribing knife"...The surface roughness of polished silicon wafer is less than 0.2 nm.The cutting edge of the knife is only 1/10 of the diameter of a hair.The extremely precise "cutting, grinding and polishing" process cannot be completed without the support of high-end super-hard material products.
"In view of the major demand of high efficiency and precision processing in China's chip industry, we have successfully developed a whole series of super-hard material grinding tools for chip processing after more than ten years of tackling the problem, breaking the foreign technology monopoly at one fall, and now we have realized import substitution."July 20, Zhengzhou abrasive grinding institute Co. LTD., deputy Secretary of the Party Committee Wang Weitao told reporters.
Located in the self-created area of Zhengluo, the enterprise is known as the "three mill" in the industry.Walking here, you will feel that what it "grinds" out are not only the manufacturing technology of super hard materials like diamond, various precision grinding tools and matching grinding technology, but also the three kinds of temperament engraved in the bone.
What is respected here is the courage of independent innovation.
"In the early 1960s, there was an urgent need for superhard materials in the national economy.In order to break the blockade of the western countries on the production technology of synthetic diamond, the ministry of Machinery Industry at that time gave the task of focusing on the synthetic diamond experiment to Sanmilli.Looking back on the years of struggle, wang Guangzu, a white-haired retired professor and senior engineer who was a member of the research team, is still excited.
Under extremely difficult conditions, the older generation of researchers successfully developed China's first synthetic diamond in 1963.In order to make up for the shortage of synthetic diamond in processing black iron metal, China's first cubic boron nitride was successfully synthesized in 1966.With these two breakthroughs as the source, sanmo leads China's superhard material industry from scratch, from small to large, from weak to strong.
Today, China produces more than 20 billion carats of superhard materials annually, accounting for more than 95 percent of the world's total production.
What we stand by here is our commitment to "hard bones".
Superhard materials are known as the "teeth of industry".As the only comprehensive research institution in China's abrasive and abrasive industry, Sanmo has played the role of "industry booster" incisitively since its transformation in 1999, providing "excellent equipment" for many domestic manufacturing enterprises to break through technical bottlenecks.

High-precision camshaft, crankshaft and other accessories "ground" for engine and powertrain of a high-end brand automobile, in line with the most stringent international automotive industry standards;For a famous brand of household air conditioning "grinding" out of the compressor special components, energy efficient ratio is higher, longer life......
From electronic information, aerospace, to automobiles, tools, household appliances, photovoltaic and LED, sanmill has developed a series of "high, fine, sharp and special" super-hard material products in response to the constantly emerging upgrading and development needs of various industries, constantly filling the gaps in the industry, and comprehensively driving the high-quality development of the industry.
What motivates us here is the ambition to explore the blue Sea.
Walk into the National Engineering And Technology Research Center of Superhard Materials and Products, the State Key Laboratory of Superhard Abrasive Tools and Henan Functional Diamond Material Innovation Center of Sangrinding Institute and chat with researchers, you will find that, in their eyes, diamond and other superhard materials are no longer limited to the category of "tools".They keep their eyes on the frontier of international scientific research and enter a new world of diamond "functionalization" research.

"If the technology of high-grade large single crystal diamond achieves breakthrough, can the chip made of diamond material become an important support for the research and development of new high-performance computers?"
"Through the research and development of diamond-doped environmental protection materials, can effectively degrade harmful substances and directly treat sewage into clean water that meets the national environmental protection standards, so perhaps we can solve the international problem of sewage treatment in the biopharmaceutical industry?
"The development of carbon-based diamond superhard materials to replace metal as cardiac pacemakers and bone joint replacement parts can not only completely overcome the rejection of human body to metal materials, but also extremely strong and durable. Will this be a new breakthrough for the medical industry?"

The researchers of sanmo institute are working hard to turn these "question marks" into "periods" and "exclamation marks" for innovation and development.
Based on excellent diamond light, electricity, heat and chemical properties of the research and development, at present most is still in the theoretical research and exploration in the laboratory, but perhaps in the near future, these ideas will occupy the high ground of the innovative research and development, expand the new industrial development space, for the whole of superhard material industry and even the national manufacturing industry, opening out the pieces of a vast and rich "blue ocean".
