Ceramic positioning blocks
Descriptions:
The specific functions of ceramic positioning blocks mainly include the following aspects:
- High-precision positioning: Due to their extremely high manufacturing precision, ceramic positioning blocks can achieve sub-micrometer accuracy. Therefore, in fields requiring high precision such as optics and semiconductors, they can provide precise positioning functions, ensuring the accuracy of processing or installation.
- Wear resistance and durability: Ceramic materials have high hardness ,it allows ceramic positioning blocks to withstand greater pressure and wear during use without damage or deformation, thereby extending their service life.
- Good stability: Ceramic positioning blocks exhibit excellent dimensional stability and are not affected by temperature and humidity. This characteristic is particularly important for equipment operating in high-temperature and high-pressure environments, ensuring stable operation over long periods without a decrease in positioning accuracy due to environmental factors.
- Strong corrosion resistance: Ceramic materials also have excellent corrosion resistance and can remain stable in working environments with strong corrosive media, further expanding the application range of ceramic positioning blocks.
