Marble platform material: based on the quality of underground rock layers, the main mineral components of pyroxene, plagioclase measured with marble slab, a small amount of olive, biotite, and trace magnetite. After millions of years of natural aging, with a sophisticated structure, while black gloss, uniform, good stability, while the large marble slab strength, hardness, high marble tablet platform price, under heavy load can still maintain high accuracy, even if was heavy objects bump, up out of fresh ballast only. Marble slab in addition to the above features, but also has "three" features - anti-magnetic, anti-corrosion, anti-deformation. Marble slab | marble platform of physical properties: a hardness of 2-3 times higher than that of cast iron equivalent HRC> 51, Mohs hardness of 6-7; the same compressive strength of 2290-3750 kg / cm. Marble platform marble platform based on the formation of the quality of underground rock layers, after millions of years of natural aging marble slab, form extremely stable, do not worry because the conventional temperature and deformation. The rigorous physical testing and selection of granite materials, fine crystalline, hard, compressive strength of 2290-3750 kg / cm, hardness of Ta Mok's hardness 6-7. Extremely resistant to abrasion, acid, alkali, high corrosion resistance, never rust. Department of non-metallic materials due to marble, no magnetic response, no plastic deformation. Its hardness 2-3 times higher than cast iron (equivalent to HRC> 51), and therefore to maintain good accuracy. Even rock tools in use by heavy bump standard marble slab, up off the fresh ballast only, and not as metal tools, as a result of deformation and destruction of accuracy. The superior quality cast iron and steel production base parts precision measurement, to obtain high and stable accuracy.
