There are many types of ceramics, including alumina, zirconia, boron nitride, and aluminum nitride. Different materials have their own physical properties and are used in different industries and products in industrial production. There are also many types of ceramic grinders for ceramic grinding and polishing. Generally, they are classified according to the grinding surface: ceramic surface grinder , ceramic cylindrical grinder and polisher, and ceramic double-sided grinder .
Surface grinding ceramic grinders are generally aimed at zirconia and alumina ceramic materials, and are generally used in mobile phone covers, fingerprint modules, seal rings, valve plates and other hydraulic industries; this flat ceramic grinding machine can Grinding to a mirror effect can also make the surface flatness of the ceramic fingerprint module reach 1u, and the coarseness is 0.2nm, which is an ultra-high precision grinding equipment. Ceramic grinders for external grinding are generally aimed at materials such as zirconia, and are generally used in products such as ceramic ferrules, which are used in the optical fiber communication industry. The cylindricality of this kind of cylindrical grinding and polishing equipment after grinding the zirconia ceramic ferrule can be controlled within 0.0005mm.
Boron nitride is a more advanced material that is currently very popular in the industry. Because it is the hardest crystal known today, it is resistant to high temperatures and oxidation. It is a refractory material and an insulating material. Therefore, its appearance has brought surprises to industrial production. Boron nitride is commonly used in high-tech products, such as nozzles for engines in aerospace, structural materials of atomic reactors, and heat dissipation components.
In the grinding industry, boron nitride is generally used to make coarse grinding sapphire and aluminum nitride ceramic grinding discs. The grinding disc made of boron nitride has high hardness, is not easy to wear, fast grinding speed, high temperature resistance, and does not cause damage to the material being ground, so it is an excellent grinding material.
