Marble platform has the advantages of high precision, no variation, good wear resistance and so on. Marble platform can maintain accuracy and stability under heavy load and general temperature. Marble after billions of years of aging, uniform texture, good stability, high strength, high hardness, can maintain high precision under heavy load.
Because the marble is non-metallic material, no magnetic reaction, no plastic deformation. Its hardness is 2-3 times higher than that of cast iron (equivalent to HRC> 51), so the accuracy is good. In use, even if the rock tool is knocked by heavy objects, at most a few pieces of ballast will fall, and will not be as metal tools, due to deformation and damage the accuracy. It is superior to the precision measuring reference parts made of high quality cast iron and steel, and can obtain high and stable accuracy.
