China's metal cutting tool materials continue to grow
In the world-wide industry, the proportion of tool consumption is about: high-speed steel tools accounted for 35%, diamond and cubic boron nitride tools accounted for 10%, and welded carbide tools, overall carbide and indexable carbide accounted for the rest. For example, if we use cobalt-containing high-performance high-speed steel or even powder metallurgy high-speed steel (P/MHSS) to replace the common high-speed steel, our high-speed steel tool manufacturing level can also be a step up.

Manufacturing Method and Application of Diamond Cutting Tool
With the rapid development of automobile, aviation and aerospace technology, the requirements for material properties and processing technology are increasing day by day. New materials such as carbon fiber reinforced plastics, particle reinforced metal matrix composites (PRMMC) and ceramic materials are widely used. These materials have high strength, good wear resistance, low coefficient of thermal expansion and other characteristics, which determines their machining tool life is very short. The development of new wear-resistant and stable superhard cutting tools is the subject of research in many universities, research institutes and enterprises. Diamond set mechanical, optical, thermal, acoustic, optical and many other excellent properties in a body, with high hardness,

Microwave plasma chemical vapor deposition
Chemical vapor deposition CVD method to grow polycrystalline diamond film came out in the mid -1980 s. Single crystal CVD diamond began to be developed in the late 1990 s. By the early 2000 s, element 6. Carnegie, Apollo and other companies had successfully grown, but failed to form a market. At the beginning of 2012, Singapore's IIa Company commercialized colorless high-quality jewelry diamonds grown by microwave plasma chemical vapor deposition from small to carat grades. Its selling price is 1/3 to 1/2 lower than that of natural diamonds of the same grade, which shocked the natural diamond market. In fact, single crystal jewelry diamonds are only a small part of the CVD function
