Zirconia Ceramics Commonly Used Cutting Tools

However, the hardness of zirconia is so high that it is difficult to process. So what kind of cutting tools are generally used for processing zirconia ceramics?

Zirconia ceramics have excellent high-temperature resistance, corrosion resistance, and ultra-high hardness.

However, the hardness of zirconia is so high that it is difficult to process. So what kind of cutting tools are generally used for processing zirconia ceramics?

Everyone knows that the model hardness of zirconia ceramics can reach 9, while the hardness of the diamond is about 10, and the hardness of the crystal is about 7. Therefore, the hardness of zirconia ceramics is less than that of diamond and greater than that of crystal. Then when we process zirconia ceramics, we can choose diamond tools to process zirconia ceramics.

Diamond has the advantages of extremely high hardness and wear resistance, high elastic wear, and low affinity with non-ferrous metals. It can be used for precision machining of non-metallic hard and brittle materials such as graphite, high wear-resistant materials, composite materials, and other tough non-ferrous metal materials.

Main kind of zirconia ceramic cutting tools

1. Natural diamond (ND) cutting tool

Pure diamond. ND is currently known as a very hard substance with minerals, and is mainly used to prepare tool turning tools.

2. Polycrystalline diamond (PCD) tool

In order to improve the toughness and weldability of PCD blades, PCD and cemented carbide blades are often made into synthetic polycrystalline diamond composite blades (PDc).

3. CVD diamond thick film (TDF) welding cutting tool

CVD diamond thick film tool uses the CVD method to deposit a diamond thick film on the substrate to obtain independent diamond thick film material, which is a significant advantage that polycrystalline diamond cannot have.

4. Cubic boron nitride (PCBN) Cutting tool

Cubic boron nitride cutting tools are synthesized using cubic boron nitride powder and a small amount of bonding agent under high temperature and high-pressure conditions by artificial methods. Its hardness is second only to diamond (Mohs hardness 9.5), so it and diamond cutting tools are collectively called superhard Knives are also ideal materials for processing zirconia ceramics.
