Sapphire

Sapphire crystals possess excellent optical, mechanical, and chemical stability, with high strength, hardness, and resistance to erosion. They can operate under harsh conditions at temperatures nearing 2000°C. Sapphire is primarily used in LED substrates, watch lenses, and is widely applied in infrared military devices, satellite space technology, and as window materials for high-intensity lasers. It serves as an ideal substrate material for practical semiconductor applications such as GaN/Al₂O₃ light-emitting diodes (LEDs), large-scale integrated circuits (SOI and SOS), and guided nanostructure thin films. Currently, sapphire polishing slurries and grinding fluids in China still largely rely on imports. After years of continuous ...

Ceramic

This is an alumina ceramic sheet requiring mirror finishing. Typically, polishing alumina ceramics involves rough grinding with an iron disc followed by polishing with a white cloth, but this method is extremely slow—often taking 30–40 minutes with the white cloth to achieve the desired mirror surface. This is unacceptable for batch processing. Alternatively, there is another method: after rough grinding with an iron disc, directly using a tin disc for mirror polishing. However, this approach also has drawbacks, primarily the high processing cost of tin discs, making it difficult to achieve mass production. Generally, processing alumina ceramic sheets presents certain ...

Tungsten Steel

Ensuring surface gloss and right angles is a key challenge in tungsten steel polishing. Tungsten steel is primarily used for tools and cutting blades, so the sharpness of its edges directly impacts product quality. Surface gloss also helps maintain the perpendicularity of the product. During the polishing of tungsten steel tools, cloth wheels or soft polishing discs must not be used. Only polishing pads with appropriate hardness can ensure sharper right angles.
