marble platform

The marble platform is made from high-quality underground rock layers. After hundreds of millions of years of natural aging, its shape is extremely stable and there is no need to worry about deformation due to conventional temperature differences. After strict physical testing and selection, the granite material has a fine crystallization, a hard texture, and a compressive strength of -kg/cm2, with a hardness of -1 on the Ta Moth scale. It is extremely wear-resistant, acid-resistant, alkali-resistant, has high corrosion resistance and will never rust. Since marble is a non-metallic material, it has no magnetic reaction or plastic deformation. Its hardness is - times higher than cast iron (equivalent to r)dd=_ = =d_, so the accuracy is maintained well. Even if rock tools are bumped by heavy objects during use, they will only lose a few grains of stone and will not destroy accuracy due to deformation like metal tools. It is superior to precision measurement reference parts made of high-quality cast iron and steel to achieve high and stable accuracy.
