Marble plate Marble precision measuring tools, instrument platforms, also known as granite slab, using high quality ' Jinan Qing ' made by machining and hand-grinding stone. Black gloss, precise structure, texture, uniform, good stability, high strength, high hardness, can under the heavy load and the temperature accuracy and has no rust, acid and alkali resistance, wear resistance, not magnetic, type and so on.

Granite inspection plate/platform By its material effect, physical sex stable, organization careful, by impact grain off, surface not up Flash, not effect its plane precision, material stable, can guarantee long-term not deformation, line expansion coefficient small, mechanical precision high, rust, antimagnetic, insulation; granite test platform particles delicate uniform, structure stable, work surface in using in the maintenance maintenance simple, material stable, can guarantee long-term not deformation; granite test platform not by thermostat conditions block, temperature deformation small, precision keep performance good, To maintain measurement accuracy at room temperature. Measurements can be moved smoothly, without the creaky feeling, not under the influence of wet, flat good stability.

Marble is marble platform measuring precision measuring tools, instrument platforms, also known as granite slab, using high quality ' Jinan Qing ' made by machining and hand-grinding stone. Black gloss, precise structure, texture, uniform, good stability, high strength, high hardness, can under the heavy load and the temperature accuracy and has no rust, acid and alkali resistance, wear resistance, not magnetic, type and so on.

Granite (granite table) due to the formation condition of components of complex and diverse, so variety, be classified in many ways. According to the ore

Species divided into black granite, Muscovite granite and amphibolite granite, two-MICA granite and so on. According to the structure can be divided into fine granite, medium granite, coarse granite, porphyritic granite, porphyritic granite, Crystal hole granite and gneissic granite and so on. According to Deputy contained mineral can be divided into cassiterite granite, niobium iron ore granite and beryllium-containing granite, lithium-MICA granite, tourmaline-granite and so on. Common long petrified, of her rock, electrical and petrochemical and other metamorphic processes.
