Why are marble platforms used for measurements with appropriate accuracy

Marble platform is a benchmark measuring tool made of stone material, which is an ideal reference surface for the inspection of instruments and mechanical components. Especially for measurement, due to its characteristics, cast iron plates pale in comparison. The marble slab is made of "Jinan green" stone material through mechanical processing and manual precision grinding. The marble platform can maintain measurement accuracy even at room temperature. Non magnetized, able to move smoothly during measurement, without any sluggishness, not affected by moisture, and the plane is properly weighed. Marble slabs, marble platforms require suitable temperature before and after cutting and shaping, rough grinding, and fine grinding in a constant temperature chamber The precision requirement is higher than that of cast iron measuring tools Suitable for production projects with high precision requirements
