Metallographic sample preparation equipment usually includes the following types:
- Metallographic cutting machine: It is 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 high hardness, such as ceramics.
- Metallographic mounting machine: Mount the cut specimens in resin or other materials to facilitate subsequent grinding and polishing.
- For instance, hot mounting machines embed specimens by heating the resin.
- Metallographic grinding and polishing machine: Grind and polish the mounted specimens to obtain a smooth and flat surface.
- Some grinding and polishing machines have multiple grinding discs and polishing discs, which can improve work efficiency.
- Metallographic sandpaper: It is used to gradually refine the specimen surface during the grinding process.
- Common sandpaper grits come in various specifications from coarse to fine.
- Polishing cloth and polishing agent: They are used in the polishing stage to make the specimen surface bright and scratch-free.
- Polishing cloths and polishing agents of different materials are suitable for different materials.
- Metallographic microscope: It is used to observe and analyze the prepared specimens.
- There are upright and inverted types, and you can choose according to your needs.
- Prelim grinding machine: Perform preliminary processing on the specimens before grinding to remove coarse scratches.
