The world's smallest carbide milling cutter for industrial production, its diameter is only 0.01 mm, which is only one-eighth the size of a human hair. As the "most exquisite industrial tooth", this extremely small diameter milling cutter solves the problem of "stuck neck" in the production of related industries in one fell swoop, helping China's micro-processing tools to break through and upgrade faster and better.

At the beginning of 2021, a company responsible for the production of state-of-the-art equipment urgently asked China Tungsten Jinzhou Company, a subsidiary of China Minmetals, for 0.01 to 0.04mm micro-milling. anxious in mind.

On the eve of the National Day in 2021, after going through dozens of schemes and numerous experiments successively, breaking through bottlenecks such as small blade diameter, easy to break, difficult to grind the structure, and difficult to control the precision, Jinzhou Company finally produced the first 0.01mm ultra-small diameter in China. The milling cutter and the previously developed 0.01mm extremely small diameter drill form a "double sword" trend. This is the world's smallest carbide milling cutter for industrial production. Its diameter is only 0.01 mm, which is only one-eighth the size of a human hair.

In daily life, the smart phones that people use frequently are made of it, and micro-precision tools are also used in electronic information, biomedical, optical instruments, automobile manufacturing, aerospace and other fields.Editor/Ma Xue
