The main mineral components of the marble platform are pyroxene, plagioclase, a small amount of olivine, biotite, and trace magnetite. It has a black luster, structure, and has undergone billions of years of aging, with uniform texture, good stability, high strength, and high hardness. It can maintain high precision under heavy loads. Used for industrial production and laboratory measurement work.

The advantages of marble platform

The marble platform is made of large marble materials that have been mechanically processed and finely ground by hand. Black luster, uniform structure and texture, good stability. High strength and hardness. And it has the advantages of non rusting, acid and alkali resistance, non magnetization, invariance, and good wear resistance. Can maintain stability under heavy loads and normal temperatures. Marble platform is a benchmark measuring tool made of stone material, which is an ideal reference surface for the inspection of instruments, tools, and mechanical parts. Especially for high-precision measurements, due to its characteristics, cast iron plates pale in comparison.

Granite flat plate, granite flat plate, granite inspection flat plate, and instrument platform are made of "Jinan green" stone material through mechanical processing and manual precision grinding. Black luster, structure, uniform texture, good stability, high strength, high hardness, able to maintain high precision under heavy load and general temperature, and has the advantages of non rusting, acid and alkali resistance, wear resistance, non magnetization, and invariance Granite slabs are suitable for measuring tools in mechanical factories.
