The quality of metallographic sample preparation is directly related to the results of metallographic analysis. A high-quality sample surface can accurately reflect the microstructure of the material and provide a reliable basis for metallographic analysis workers' analysis data. In addition to the selection of metallographic sampling equipment, the most important factor is the selection of grinding and polishing consumables. The correct selection of grinding and polishing consumables not only enables us to obtain a perfect sample, but also greatly improves work efficiency.

    When grinding and polishing the surface of the sample, many factors need to be considered, such as material removal rate, wear resistance of the grinding surface, material composition and category, etc.

    Compared to most metal and alloy materials, QMAXIS metallographic sandpaper is a good choice. It not only provides fast material removal speed, but also causes almost no deformation. For the grinding of hard materials such as sintered carbides, ceramics, etc., diamond grinding discs are a good choice. Moreover, diamond grinding discs have an ultra long service life and are more economical than using sandpaper.

    For metallographic sampling of high hardness materials such as metals and ceramics, QMAXIS's MetDGD diamond grinding disc has good results: high material removal rate, and can be used for both rough and fine grinding. Used in automatic preparation systems and high-speed manual preparation systems, it can improve grinding efficiency and achieve ideal grinding surfaces.
