The importance of polishing for advanced ceramics

November 15, 2024

The importance of polishing is fully evident in the manufacturing of Advanced Ceramics, where it plays a pivotal role in the performance, quality, and appearance of finished products. The purpose of polishing is to minimize and eliminate visual defects, burrs, particles, and other non-uniformity on the surface of Ceramic parts so that the ceramic surface would be flatter and smoother to further improve the appearance quality of fine ceramic products in 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 ceramic material's surface 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 affect the optical performance and beam path accuracy. For example, the importance of polishing for optical ceramics is its appearance.

As an advanced material in the optical field, the surface quality and properties of optical ceramics affect their functions and applications of final devices. The significance of polishing is that it can improve optical quality, reduce light scattering and reflection, improve light transmittance and transmission performance, and maintain long-term optical stability. Additional polishing can also elevate optical ceramics' wear and corrosion resistance and improve their strength and durability in harsh environments. These outstanding features enable optical ceramics to perform well in optical devices, laser technology, optical communication, and optical detection, 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 parameters and processing technology in the polishing process, precise machining and fine-tuning of ceramic products can be realized to ensure that they meet the design requirements.

③ Surface surfacing

Remove bumps and depressions on the surface of ceramic products to improve surface flatness. Improving surface flatness can reduce the contact pressure and friction between the grinding media and the product surface and reduce wear and the abrasive cutting effect on ceramics. Therefore, polished ceramic products with flat surfaces generally have better wear resistance. This is critical for applications requiring 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 friction resistance and adhesion with collaborating parts, reducing wear and abrasive damage. Polishing can also remove microscopic sharp edges and surface roughness, reduce particle scaling and scraping, and improve wear resistance. This is particularly important for applications requiring wear and fatigue resistance, such as ceramic bearings and ceramic cutting tools.

Our facility offers a selection of polishing approaches for Technical Ceramics. The best level after polishing treatment is RA0.05.
