2. It dosen't only own the interest of black gloss, precise construction, and outstanding characters - nice stability, high strength and hardness, etc. But also it is no rust, acid & alkali-proof, no magnetization, nice abrasion resistance and Can keep stable at normal or high tempreture.

3. the main mineral ingredients of granite are pyroxene, anorthose, less olivine, black mica and less magnetite. Aging through hundreds of millions years, the granite can still retain even character, stable, high strength and hardness, and can keep high precision at Heave duty. It is suitable for industrial production and measuring works at laboratory.

 FAQ:

1. What are the advantages of granite surface plates?

High accuracy and easy maintenance Uniformity in hardness Easy to clean Wear resistance Anticorrosion Accurate under load conditions Non-magnetic Thermal stability Low porosity Low maintenance cost

2. What are the disadvantages of granite surface plates?

The disadvantages are not with standing impact and beating, high humidity brings about granite deformation, and the hygroscopicity is 1%.

3. How to install the granite surface plate?

The granite surface plate adjustable mounts on every supporting pointes should be well adjusted in order to bear averaged force. Our professional specialists are in charge debugging the surface plates until getting qualified precision grade.

4. What we should pay more attention on using granite surface plate?

When using granite surface plate, please put down carefully and it is not allowed to move the rough workpieces on surface plates in case of any scratched, dented in places. And please using it under constant temperature condition.

5. How to protect the granite surface plate, when we don't use it ?

When don't use the granite surface plate, the plate should be isolated with the outside world, so as to effectively protect the surface of the marble platform from being damaged.
