How to use TNP series metallographic grinding and polishing machines with metallographic consumables for better results?

When the TNP series metallographic grinding and polishing machine is paired with metallographic consumables, choices should be made scientifically based on material characteristics and grinding stages.
In the coarse grinding stage, large-grit metallographic sandpaper (such as 80 mesh, 120 mesh) can be used with higher rotation speeds to quickly remove the oxide layer and machining marks on the sample surface; in the fine grinding stage, switch to fine-grit sandpaper (such as 400 mesh, 800 mesh) and lower the rotation speed to reduce surface scratches; in the polishing stage, select polishing cloth paired with diamond paste and run at low speeds to obtain a mirror effect.
For high-hardness metals, wear-resistant silicon carbide sandpaper can be chosen; soft metals are suitable for aluminum oxide sandpaper to avoid scratching the surface. In addition, it is necessary to ensure that the consumables fit tightly to the grinding disc during use, and to regularly replace severely worn consumables to ensure stable grinding and polishing effects.
