Traditional superhard cutting tools include Nature Diamond, synthetic diamond and Cubic Boron Nitride. Because of the small amount of the nature diamond, it is difficult to satisfy the increasing of the industry，so many manufacturers begin to use synthetic diamond and cubic boron nitride tools. In current times, superhard cutting tools are mainly pcbn and its composite materials.
The superhard cutting tools Type and the performance
1. CVD Diamond didn’t include any metal catalyst, and the stability and the hardness both similar with nature diamond. And it has good impact resistance and high hardness, is the hardest materials in the world. So in some occasion, cvd diamond can replace nature diamond. However the thermal stability is not good, and the toughness is not good, it is easily appear carbonization phenomenon in high temperature. So it can’t be used for machining Tungsten carbide, steel alloy, ect materials.
2. Cubic Boron Nitride Tools
CBN Inserts can be divided into 3 types, pcbn inserts, solid cbn inserts, and coating cbn insert. And pcbn insert is the most widely used, it has high wear resistance and thermal stability. And the raw materials can obtain easily, the costs also will be lower than the diamond tools. So it has been used by so many different industries.
The application of superhard cutting tools materials in cold processing industry
Used for Turning Process
When turning steel parts, superhard cutting tools can replace grinding in most machining process. And the cutting depth also larger than grinding process, so that improve the working efficiency and lower the costs.
When turning cast iron parts, they can be used with high cutting speed, Which will improve the efficiency obviously.
Also superhard cutting tools can be used for other process, like milling, boring, drilling, and others, especially for machining high hardness materials, superhard cutting tools can be used with high cutting speed and high efficiency.
