The marble measurement platform is taken from high-quality rock layers underground, and after billions of years of natural aging, its shape is extremely stable, so there is no need to worry about deformation due to conventional temperature differences. The granite material, which has undergone strict physical testing and selection, is finely crystalline, hard in texture, with a compressive strength of 2290-3750 kg/square centimeter and a hardness level of 6-7 Mohs hardness. Extremely resistant to wear, acid, and alkali, with high corrosion resistance and never rusting. Due to the non-metallic nature of marble, there is no magnetic reaction or plastic deformation. Its hardness is 2-3 times higher than cast iron (equivalent to HRC>51), so its accuracy retention is good. In use, even if a rock tool is hit by a heavy object, at most a few pieces of debris will be dropped, and it will not damage accuracy due to deformation like metal tools. It is superior to precision measurement reference parts made of high-quality cast iron and steel, and can achieve high and stable accuracy.

　　Origin of marble measurement platform

　　The marble platform requires marble materials that are available in Shandong and Inner Mongolia. Among them, Shandong has better materials, while Inner Mongolia cannot compare with Shandong. The main production area is concentrated in Jinan, Shandong.

　　Advantages of marble measurement platform

　　Made from high-quality natural marble through mechanical processing and hand crafted precision grinding. Black luster, precise structure, uniform texture, and good stability. High strength and hardness. And it has advantages such as no rust, acid and alkali resistance, no magnetization, no change in shape, and good wear resistance. Can maintain stability under heavy loads and general temperatures.

　　Marble is a precision reference measuring tool made of natural stone materials, which is an ideal reference plane for the inspection of instruments, precision tools, and mechanical components. Especially for high-precision measurements, due to its unique characteristics, cast iron flat plates pale in comparison.

　　Marble measurement platform, granite flat plate, precision granite flat plate, granite inspection flat plate, instrument platform, made of high-quality "Jinan blue" stone material through mechanical processing and manual precision grinding. Black luster, precise structure, uniform texture, good stability, high strength, high hardness, can maintain high accuracy under heavy loads and general temperatures, and has advantages such as rust resistance, acid and alkali resistance, wear resistance, non magnetization, and unchanging shape. Granite flat plates are suitable for measuring tools in mechanical factories.
