Purpose of marble platform: The marble platform is suitable for industrial production and laboratory measurement work. The main mineral components are pyroxene, plagioclase, a small amount of olive, biotite, and trace magnetite, with a black luster and structure. After billions of years of aging, it is uniform, stable, strong, and hard, and can maintain high precision under heavy loads.
