The Mineral composition of Granite Surface Plate

The main mineral components of granite surface plate are pyroxene, plagioclase, minor olivine, biotite, and trace magnetite, granite surface plate has black gloss, structural precision, after millions of years of aging, even texture, good stability, high strength, high hardness, can be maintained high accuracy under heavy load. Suitable for industrial production and laboratory measurements.

Granite platform is reference measurement tools made of natural stone material, used for testing instruments, precision tools, machinery parts, it is an ideal base. Especially for high-precision measurements, because of its unique characteristics, it is widely used.
