Product description:

The accuracy of the marble inspection platform is based on the advanced national standards, the planar tolerance: JB/T 7975-1999 marble inspection platform standard.

The main features of our company.

Marble test platform is made of natural stone material precision measuring tools, the instruments and meters, precision instruments, mechanical parts inspection, is the ideal datum, especially for high precision measurement. Marble test platform, the main mineral composition of pyroxene, plagioclase, a small amount of olivine, biotite, and trace magnetite, black gloss, sophisticated structure, uniform texture, good stability, high strength, hardness, can maintain under heavy load and high precision.

Granite is based on the underground high quality rock layer, which is extremely stable in nature after a million years of natural aging. No need to worry about deformation due to conventional temperature difference.

According to the strict physical test and selection of granite stone, the crystallization is fine, the texture is hard, the compressive strength is 2290-3750kg/cm2, hardness reaches 6-7 grade of Mohs hardness. Extremely resistant to wear, acid and alkali resistance, high corrosion resistance, never rust. Marble test platform proportion: 2970-3070 kg / ㎡； Compressive strength: 245-254 N/m: linear expansion coefficient 4.61 x 10-6 / ℃, bibulous rate is: ﹤ 0.13% shore hardness: Hs70 above, granite test platform, marble platform for industrial production and laboratory measurement work.
