We have created a case study document on sapphire polishing using the diamond grinding pad "PLATO"!

ピュアオンジャパン

Diamond grinding pads are sheet-like grinding tools that secure diamond abrasives to metal plates or urethane pads. They are used by adhering them to the polishing plates currently in use. In recent years, they have gained attention as an alternative to free abrasives from the perspective of environmental impact and maintenance. In this experiment, we investigated the grinding rate and surface roughness on sapphire samples, which are difficult-to-grind materials. The results showed that both the 'PLATO' and 'SQUADRO' grinding pads were effective, with the PLATO-40 µm demonstrating a very high grinding rate. The possibility of achieving sapphire grinding with fixed grinding pads, a long-standing challenge in the industry, is now becoming clearer. If you are interested, please feel free to contact us through the inquiry form.

Diamond grinding pad "PLATO": A grinding pad that can also cut sapphire.
Metal bond grinding pads with high grindability, long lifespan, and compatibility with almost all cooling lubricants (coolants).

The diamond grinding pad PLATO is recommended for grinding materials such as ceramics, glass, and various metals. It maintains a high grinding rate due to diamond abrasives fixed with a metal bond. PLATO is highly praised for its excellent grindability and long lifespan. Because it is metal bond type, it is compatible with almost all cooling lubricants (coolants). 【Examples of PLATO processing are now available】 We have created a document summarizing examples of processing using PLATO for sapphire, white alumina, and sample polishing.
