A fence has three stakes, and a hero has three helpers. If you want the fence not to fall down and the help not to fall apart, you must have a strong relationship. In the process of metallographic sample preparation and polishing, there is also a relationship between metallographic polishing machines and metallographic sandpaper. If the relationship between these two friends is stable, then your sample polishing will be worry free, but once either party in this relationship has problems, then your sample will also be in trouble.


For many newcomers who have just started the industry, due to their limited understanding of the metallographic polishing machine used, they may not be able to grasp the problems that may arise during sample polishing. How to choose metallographic sandpaper? How to use metallographic sandpaper? Will hastily changing sandpaper damage this relationship and cause damage to the metallographic polishing machine and samples.


Today, the metallographic editor of Chain Energy will present to you a pair of good friends in the metallographic field, who are MetLab's fully automatic grinding and polishing machine METPOL– A and American QMAXIS silicon carbide metallographic sandpaper.

    Original imported MetLab fully automatic metallographic grinding and polishing machine METPOL– A. It has both manual mode and flexible application. Programmable; Compatible with automatic liquid feeding system, achieving full automatic control. Fixture size: 1-1.5in, 25-40mm, capable of holding 6 samples simultaneously; The anti-corrosion steel body is sturdy and durable. The grinding wheel has adjustable rotation speed and steering, a super large color touch control system, a comprehensive cooling and cleaning system, drainage system, splash cover, dust cover, and other detailed designs are all very convenient. Suitable for metallographic grinding and polishing of various materials, it is an ideal automatic metallographic grinding and polishing equipment for metallographic laboratories.

    QMAXIS imported silicon carbide metallographic sandpaper from the United States can cover all material grinding requirements, strictly control abrasive particle size, ensure consistent depth and pattern of grinding marks, and prevent sample damage and rework. During the sample polishing process, it is ensured that surface damage is minimal, effectively reducing subsequent processing volume, shortening preparation time, and improving work efficiency. When encountering fragile or sensitive materials, the material can also be gently removed and excellent surface finish can be provided.

    Metallographic sandpaper plays a significant role in sample grinding and polishing. If inappropriate metallographic sandpaper is used, it can cause wear on the sample, and in severe cases, affect the progress of the entire work and the results of research and development. Good metallographic sandpaper, good friend, just like MetLab fully automatic grinding and polishing machine METPOL– A and silicon carbide metallographic sandpaper are paired together to achieve invincibility.
