SE Series Grinding Stones for Glass Polishing Finish

SE Series Grinding Stones for Glass Polishing Finish

The abrasive has a high grit ratio, providing better gloss than rubber-based bonded abrasives, and allows for stable finishing and polishing.

The SE series polishing stones for glass finishing use only high-purity cerium oxide, which is cured with resin, resulting in a high abrasive grain ratio that provides better gloss than rubber-based bonded stones, allowing for stable finishing polishing from start to finish. They are ideal for the final polishing process and glossing of the edges of plate glass. For more details, please contact us or refer to the catalog.

Whetstone "SE Series"

Whetstone "SE Series"

Final polishing and gloss finishing stone for achieving a stable finish.

The "SE Series" is a grinding stone primarily used for final polishing and gloss finishing of edge areas (cob surface) of flat glass, LCD cover glass, and the like. To stabilize the polishing surface, improve the working environment, and effectively utilize cerium oxide polishing materials, cerium oxide is immobilized, achieving a consistent finish. Additionally, by immobilizing the cerium oxide polishing material, it helps to reduce the scattering of the polishing material, contributing to an improved working environment and a reduction in usage. 【Features】 ■ For glass polishing finishing ■ Ideal for gloss finishing ■ Immobilization of cerium oxide polishing material ■ Improvement of working environment ■ Reduction in usage *For more details, please refer to the catalog or feel free to contact us.

Introduction of the mold grinding stone "YHS" - Samples available.

It has a strong retention of sulfur intensity, is difficult to break, and has excellent workability.

The product we would like to introduce from our main product line of mold grinding stones is the product called "YHS." This is a grinding stone that has sulfur impregnated into a WA grinding stone. By adhering sulfur to the pore walls of the grinding stone, it can prevent grinding marks on molds. It has a moderate strength retention of sulfur, making it less likely to break and excellent in workability. Additionally, the lubricating effect of sulfur improves the surface roughness of the mold and significantly reduces the wear of the grinding stone. The hardness of the grinding stone is of type "I." (Note) As it is a flammable solid, please ensure that the grinding stone is dried naturally. It may cause a fire. Currently, we are offering free samples, so please feel free to contact us for more details!! ↓↓↓ ---------------------------------- Yamato Seito Co., Ltd.
