CBN (Cubic boron nitride)-a important parts processing tool materials

With the rapid development of the automotive industry, but also led the automotive industry downstream, such as the rapid rise of auto parts and other industries. And with the mass production of cars, a lot of processing auto parts mechanical processing plants are mass production, such as automotive gears, gear shaft and other components.

Choosing the right tool material for finishing a part is especially important because it not only requires high precision but also high quality, and need to ensure process efficiency in batch production.

Currently, there are three kinds of tool materials on the market, they are coated carbide cutting tools, ceramic cutting tools and cubic boron nitride tool, although the hardness and strength of coated carbide tools to a certain extent higher than the uncoating of cemented carbide Tool, but because of the wear-resistant surface layer is thin, prolonged processing  lead the surface wear-resistant layer used up, the performance then the same as uncoated cutting tools. High-volume processing is not recommended to choose coated carbide cutting tools, compare to CBN cutting tool,affecting processing efficiency, small processing gear, in the case of without affecting the processing efficiency,then can choose a appropriate coating carbide cutting tools.

Ceramic cutting tools ,needless to say, brittle,it's well known that ceramic cutting tools can not be intermittent cutting, and suitable for finishing workpiece the hardness between HRC45-55, so when no intermittent cutting,small remaining choose ceramic tool is more economical.

Cubic boron nitride(CBN) tool compared to the above two kinds of cutting tools, not only excellent hardness, high strength, and good wear resistance, although the traditional cubic boron nitride tool brittleness is an indisputable fact, but compared to the ceramic tool is still with A certain impact resistance.
