I produced the granite square box and has: high precision, no rust, acid, non-magnetized, the same type, and good abrasion resistance. It remains stable under heavy duty and general temperature. Granite square box / granite square box is a precision reference measurement tools, natural stone material, for instruments, precision tools, machinery parts of the test, it is an ideal base, granite square box special It is used for high-precision measurements. Granite square box based on the quality of the rock layers underground, after millions of years of natural aging, form extremely stable, do not worry because the conventional temperature and deformation. Granite square box / granite square box through rigorous physical testing and selection of granite materials, crystal fine, hard texture. Because granite-based non-metallic materials, no magnetic response, no plastic deformation. Its high hardness, so to maintain good accuracy. Granite square box in use, even by heavy bump, up out of fresh ballast only. The superior quality granite square box made of cast iron and steel parts precision measurement reference, to obtain high and stable accuracy.
