In the process of preparing metallographic samples, most experimental personnel prefer to use silicon carbide metallographic sandpaper for grinding and polishing, but the service life of sandpaper is relatively low. A piece of sandpaper can only be used for about 2-3 minutes and needs to be removed and thrown away. Moreover, frequent replacement of sandpaper can greatly reduce our work efficiency.


If sandpaper is discarded and diamond grinding discs are used, it can greatly reduce the grinding and polishing time. A Aka Pietto diamond grinding disc from Akasel, Denmark can approximately replace 100-200 sheets of sandpaper. Different micrometers and disc colors result in unique loss compensation surface design, which increases the smoothness of the sample surface and prolongs the service life of the grinding disc. A standard grinding disc can provide medium removal speed, achieving ideal surface effect and good edge protection.


Aka Pianto grinding discs have good durability, significantly reducing the frequency of disc replacement. Replacing traditional diamond and polishing cloth with it will reduce the level of confusion during surface preparation. Like sandpaper, it only needs to be used in conjunction with water. Three edges of the grinding disc; Little Ears; Conveniently removing the grinding disc from the magnetic disc is both user-friendly and convenient.

Aka Pianto grinding disc must be trimmed with a Sharpening stone before its first use. When it is not used continuously, it can be maintained regularly to extend its service life.


This resin based colored diamond grinding disc is suitable for materials such as ceramics, ores, cement, mold steel, medium and low carbon alloy steel, especially for most engineering metals such as steel and aluminum.


Which diamond grinding disc is more appropriate for the preparation of ceramics? Many people believe that metal based diamond grinding discs should be used for harder ceramics. In fact, as long as it is ceramic, it itself is a porous structure with brittleness, and it is not recommended to use metal based grinding discs. However, during rough grinding, using a metal based material is not a problem and is more durable. The resin based material will be more suitable for subsequent grinding. In addition, it is possible to grind and polish soft ceramics using metallographic sandpaper, but it is still recommended to use resin based colored diamond grinding discs.
