Introduction of Marble Slabs and Marble Platforms: Marble slabs and marble platforms are made of high-quality underground rock layers. After hundreds of millions of years of natural aging, the shape is extremely stable, so you don't have to worry about deformation due to conventional temperature differences. After strict physical tests and selected granite materials, the crystals are fine, the texture is hard, the compressive strength is 2290-3750 kg / cm2, and the hardness is 6-7 Mohs. Extremely resistant to abrasion, acid and alkali, has high corrosion resistance and will never rust. Because marble is a non-metallic material, there is no magnetic reaction and no plastic deformation. Its hardness is 2-3 times higher than that of cast iron (equivalent to HRC> 51), so the accuracy is maintained. In use, even if a rock tool is bumped by a heavy object, at most a few stones will be dropped, and the precision will not be damaged due to deformation like a metal tool. It is superior to precision measurement reference parts made of high-quality cast iron and steel, and can obtain high and stable accuracy.
Marble slabs and platforms are made of high-quality natural marble materials and processed by hand. Black gloss, precise structure and uniform texture, good stability. High strength and high hardness. And has the advantages of: non-rust, acid and alkali resistance, non-magnetization, invariant, good wear resistance and so on. Can be stable under heavy load and general temperature.
Marble slabs (marble platforms) are precision reference measurement tools made of natural stone materials. They are ideal reference surfaces for the inspection of instruments, precision tools and mechanical parts. Especially for high-precision measurement, cast-iron slabs are dwarfed by its unique characteristics. Marble slabs and marble platforms are suitable for industrial production and laboratory measurement work. The main mineral components are pyroxene, plagioclase, a small amount of olives, biotite and trace magnetite. It has a black gloss and precise structure. After billions of years of aging, it is uniform, stable, strong, and hard. Maintain high accuracy under load.
The marble slabs and marble platforms produced by our factory are made of high-quality "Jinan Qing" natural granite through mechanical processing and hand-polished. Black gloss, precise structure, uniform texture, good stability, high strength and high hardness. Can be stable under heavy load and general temperature. Granite platforms are precision reference measurement tools made of natural stone materials. They are ideal reference surfaces for the inspection of instruments, precision tools and mechanical parts, especially for high-precision measurement. Granite is made from high-quality underground rock layers. After hundreds of millions of years of natural aging, its shape is extremely stable, so you don't have to worry about deformation due to normal temperature differences. After strict physical tests and selected granite materials, the crystals are fine and the texture is hard. Because granite is a non-metallic material, there is no magnetic reaction and no plastic deformation. Because of its high hardness, it maintains accuracy. In use, even if a rock tool is hit by a heavy object, at most a few stones will be dropped. It is superior to precision measurement reference parts made of high-quality cast iron and steel, and can obtain high and stable accuracy. For example, the 1000 × 630mm grade '00' marble slabs and marble platforms produced by our factory can maintain the original accuracy after being left for one year.
Characteristics and advantages of marble slab (marble platform):

  1. After long-term natural aging, the structure of the rock is uniform, the linear expansion coefficient is extremely small, the internal stress completely disappears, and it does not deform, so the accuracy is high.
  2. Good rigidity, high hardness and strong wear resistance.
  3. It is not afraid of acid, corrosive matter, does not rust, does not need to be oiled, is not easy to stick to dust, maintenance, convenient and simple, long service life.
  4. Does not appear scratches, is not prevented by constant temperature conditions, and can maintain temperature measurement accuracy at normal temperature.
  5. Non-magnetized, can move smoothly during measurement, no stagnation, and not affected by humidity.
