How to polish zirconia ceramics into a mirror surface?

How to polish zirconia ceramics into a mirror surface?

Since zirconia ceramics have relatively unique properties, and they have been valued in the market, the most important thing is to attract the development and research of researchers, so how can zirconia ceramics be polished into a mirror surface? Next, Pintejin ceramics will introduce to you a bit.

The basic method of ceramic material machining: ceramic materials usually need to go through blank cutting, grinding, grinding and polishing and other processes to make the required parts.

Product categories: ceramic plungers, ceramic pump cores, ceramic valve cores, ceramic pistons, ceramic bushings, ceramic suction cups, microporous ceramics, etc.; materials: alumina, zirconia, silicon nitride, silicon carbide.

Grinding and polishing is a super-finishing method that uses free abrasives to remove finely processed surface materials to achieve machining results.

How to polish zirconia ceramics into a mirror surface

In the ultra-finishing and finishing of ceramic materials, especially in the precision machining of ceramic balls for ceramic bearings, grinding and polishing have an irreplaceable position.

From the perspective of material removal mechanism, grinding is a machining method between brittle failure and elastic removal of zirconia ceramics, while polishing is basically carried out within the elastic removal range of materials.

Grinding and polishing machining due to the small removal of zirconia ceramic materials, the machining efficiency is low; the removal rate has a greater relationship with the toughness of the added zirconia ceramic materials, the higher the toughness of zirconia ceramics, the lower the machining efficiency of zirconia ceramics, generally Only used in the final process of superfinishing zirconia ceramics.

Grinding and polishing zirconia ceramic materials generally use a flat polishing machine to polish alumina ceramics with iron discs.

Then use white cloth for polishing, but this efficiency is very slow, often white cloth polishing takes 30-40 minutes to achieve the desired mirror surface.

Optical materials such as optical glass and sapphire, semiconductor materials such as silicon wafers and GaAs substrates, and ceramic materials such as zirconia ceramics and alumina ceramics are mostly processed by grinding and polishing.

The above is how to polish zirconia ceramics to mirror surface brought by Pintejin Ceramics. Pintejin Ceramics is a manufacturer specializing in the production and machining of ceramics, focusing on the machining of alumina ceramic parts and zirconia ceramics, and can process ceramic products according to your needs.
