What are the advantages of marble platforms

The main characteristics of marble platforms are stable accuracy and easy maintenance. The reasons are as follows:

① The marble platform has a dense organizational structure, smooth surface, and low roughness values;

② After long-term aging, the internal stress of marble disappears, the material is stable, and it will not deform;

③ Acid resistant, alkali resistant, and magnetic resistant;

④ Will not get damp or rust, easy to use and maintain;

⑤ Small coefficient of linear expansion, less affected by temperature;

⑥ After collision or scratch on the working surface, only pits will be formed, without any protrusions or burrs, which has no impact on the measurement accuracy.
