Metallographic sampling equipment usually includes the following types:

1. Metallographic cutting machine: used to cut large samples into sizes and shapes suitable for subsequent processing.

-For example, low-speed diamond cutting machines are suitable for cutting materials with higher hardness, such as ceramics.

2. Metallographic embedding machine: Embed the cut sample into resin or other materials for subsequent grinding and polishing.

-For example, a hot inlay machine embeds samples by heating resin.

3. Metallographic polishing machine: Grind and polish the embedded sample to obtain a smooth and flat surface.

-Some grinding and polishing machines have multiple grinding and polishing discs, which can improve work efficiency.

4. Metallographic sandpaper: used to gradually refine the surface of the sample during the grinding process.

-Common sandpaper sizes range from coarse to fine.

5. Polishing cloth and polishing agent: Used during the polishing stage to achieve a shiny and scratch free surface on the sample.

-Polishing cloths and polishing agents of different materials are suitable for different materials.

6. Metallographic microscope: Observe and analyze the prepared sample.

-There are two types: upright and inverted, choose according to your needs.

7. Pre grinding machine: Conduct preliminary treatment on the sample before grinding to remove coarse scratches.
