Do You Know The Importance of Polishing for Advanced Ceramics?

The importance of polishing is totally self-evident in the manufacturing of Advanced ceramics, where it plays a critical role in the performance,quality and appearance of the finished products. Polishing purpose is to minimize & remove visual defects, burrs, particles and other non-uniformity on the surface of Ceramic parts, so that the ceramic surface would be more flat and smooth to further improve the appearance quality of fine ceramic products in the practical applications.

Polishing can have positive effects on the following aspects of advanced ceramics:

① Surface Roughness:

It can remove the roughness and unevenness of the surface of the Ceramic material to achieve a higher surface finish. This is critical for applications such as optical components, laser components, semiconductor ceramics, etc., because the surface roughness will directly affects the optical performance and accuracy of beam path. For example, the importance of polishing for optical ceramics is appearance.

As an advanced material used in the optical field, the surface quality and properties of optical ceramics definitely impact their functions and applications of final devices. The importance of polishing is that it can improve optical quality, reduce light scattering and reflection, enhance light transmittance and transmission performance, as well as maintain long-term optical stability. Further polishing can also elevate the wear resistance and corrosion resistance of optical ceramics, and enhance its stability and durability in harsh environments. These outstanding characteristics enable optical ceramics to perform well in the fields of optical devices, laser technology, optical communication and optical sensing, meeting the needs of high precision, high definition and demanding optical applications.

② Size and Shape Accuracy:

To help ceramic products achieve rigorous size and shape accuracy. By controlling the processing parameters and technology in the polishing process, the precise machining and fine tuning of ceramic products can be realized to ensure that they meet the design requirements.

③ Surface Flatness:

eliminate the bumps and depressions on the surface of ceramic products to improve the surface flatness. The improvement of the surface flatness can reduce the contact pressure and friction between the grinding media and the product surface, and reduce the wear and abrasive cutting effect on the ceramic. Therefore, polished ceramic products with a more flat surface usually have better wear resistance. This is critical for applications that require highly flat surfaces such as Precision ceramic structural parts, ceramic seal components, etc., to ensure their performance and reliability.

④ Other Surface Quality and Wear Resistance:

polishing can improve the surface quality of ceramic products, making them smoother and more delicate. Smooth surfaces reduce frictional resistance and adhesion with collaborative parts , reducing wear and abrasive damage. Polishing can also eliminate the microscopic sharp edges and roughness of the surface, reduce the embedding and scraping of particles, and improve wear resistance. This is particularly important for some applications that require wear resistance and fatigue resistance, such as ceramic bearings and ceramic cutting tools.
