Marble platform, the main mineral component of pyroxene, plagioclase, minor olivine, biotite and traces of magnetite, a black gloss, structural precision, after millions of years of aging, even texture, good stability, high strength, high hardness, able to maintain high accuracy under heavy load. Used in industrial production and laboratory measurements. 
 Navistar also known as granite marble platform platform is made of natural stone materials precision reference measurement tools, instruments, precision tools, machine parts inspection, is the ideal base level, marble platform (Flower stone platform), especially for high-precision measurement. Based on the quality of underground granite rock, after millions of years of natural aging, form extremely stable, do not worry about the normal temperature and deformation. Granite platform in rigorous physical testing and selection of granite materials, fine crystalline, hard. Department of non-metallic materials as granite, no magnetic response, no plastic deformation. Marble platform of its high hardness, so to maintain good accuracy. 
 Hangxing marble platform (granite platform) and the features and benefits: 
 1, by the long-term natural aging rock, organizational structure, uniform, linear expansion coefficient is extremely small, the stress disappear, no deformation, so high accuracy. 
 2, rigid, high hardness, wear resistance. 
 3, afraid of acid, alkali material erosion, will not rust, not oiled, sticky dust is not easy to maintain, convenient and simple maintenance, long service life. 
 4, no scratches, not constant temperature conditions to prevent, at room temperature can maintain the amount of accuracy. 
 5, no magnetization measurements can move smoothly, without Zhise sense, free from damp the impact of plane that set good. 
 Marble platform in use (granite platform) by heavy objects even when the bump, just up off the fresh ballast. Marble platform (granite platform) it is better than high-quality cast iron and steel production base of precision measurement parts, to obtain high and stable accuracy. I produced a 1000 × 630mm '00 'level flat rock, put up a year later, still maintaining the original accuracy unchanged.
