I believe every metallographic engineer has used countless types of metallographic sandpaper, such as coarse and fine, silicon carbide, alumina, adhesive backed, adhesive free, and so on. Especially for non adhesive metallographic sandpaper, it is necessary to use clamps to fix it on the working aluminum plate, and then grind the sample.
So, here's the problem. Frequent use of clamps can easily wear out working aluminum plates, and the cost is of course very high! Furthermore, the clamps have fatigue, and over time, it is difficult to ensure the flatness of the sandpaper they hold, which can easily cause the surface of the sandpaper to be uneven and affect the grinding of the sample, leading to an increase in scrap rate. However, due to the relatively cheap and more economical price of non adhesive metallographic sandpaper, it is also difficult to give up.
In view of this, QMAXIS in the United States has launched a hard core metallographic consumables&flash& Flash; Rubber disc, non adhesive metallographic sandpaper with its second changing magnetic backing, the above problems are easily solved!

The above photo is a rubber disc from QMAXIS in the United States. Sorry! Due to my lack of photography skills, I took pictures with my phone. I apologize for any inconvenience caused. Let's take a look.
This rubber disc comes with adhesive backing on one side and magnetic backing on the other. It can completely replace iron discs. The magnetic side attracts the magnetic disc, and the adhesive backing side is used to stick non adhesive metallographic sandpaper. This adhesive backing can be reused. After using a grain size of metallographic sandpaper, it can be removed from the top, thoroughly rinsed with water, and then pasted with the same grain size of metallographic sandpaper used in the next process. In this cyclic use, each rubber disc can be repeatedly pasted with hundreds to thousands of pieces of non adhesive metallographic sandpaper. Therefore, this is really a blessing for laboratories that use a large amount of non adhesive metallographic sandpaper, saving costs and simplifying work processes.

Moreover, the cost savings can be quantified. After rough calculation, I found that preparing a sample using rubber discs and non adhesive metallographic sandpaper can save approximately 24% of the overall cost. This hard core metallographic consumable, with adhesive free metallographic sandpaper and its second changing magnetic backing, is both easy to use and economical. Who wouldn't love to use it?
