Why do many manufacturers choose CNC machine tool column castings

The main mineral components of CNC machine tool column castings are pyroxene, plagioclase, a small amount of olivine, biomica and trace magnetite, black gloss, precision structure, after hundreds of millions of years of aging, uniform structure, good stability , High strength, high hardness, can maintain high precision under heavy load. Used in industrial production and laboratory measurement.

CNC machine tool column castings are taken from fine underground rock formations. After hundreds of millions of years of natural aging, the shape is extremely stable, and the loader counterweight does not need to worry about deformation caused by traditional temperature differences. Strict physical tests and selected granite materials have dense crystals and hard texture, with a compressive strength of 2290-3750 kg/cm2 and a hardness of 6-7 on the Mohs scale. Good abrasion resistance, acid and alkali resistance, high corrosion resistance, long-term no rust.
