Product Introduction

Marble slab (marble platform,), product alias: marble slab, marble platform, granite slab, granite platform, granite slab, granite platform, marble slab (marble platform,) Precision: Referring to advanced national standards, flatness tolerance according to JB/T, 7975-1999 Rock slab standard.

Marble slabs and platforms are made from high-quality underground rock layers that have undergone billions of years of natural aging, resulting in extremely stable shapes without worrying about deformation due to conventional temperature differences. After rigorous physical testing and selection, the granite material has fine crystals, a hard texture, a compressive strength of 2290-3750 kg/cm², and a hardness of 6-7 Mohs hardness. Extremely wear-resistant, acid resistant, alkali resistant, with high corrosion resistance, and will never rust. Due to its non-metallic nature, marble has no magnetic reaction and no plastic deformation. Its hardness is 2-3 times higher than cast iron (equivalent to HRC>51), so it has good accuracy retention. Even if rock tools are hit by heavy objects during use, they will only drop a few pieces of gravel at most, and will not damage accuracy due to deformation like metal tools. It is superior to precision measuring reference parts made of high-quality cast iron and steel, and can achieve high and stable accuracy.

Marble tablet, marble platform is made of high-quality natural marble material processed by machinery and finely ground by hand. Black luster, precise structure, uniform texture, and good stability. High strength and hardness. And it has the advantages of non rusting, acid and alkali resistance, non magnetization, invariance, and good wear resistance. Can maintain stability under heavy loads and normal temperatures.

Marble flat (marble platform) is a precision reference measuring tool made of natural stone materials, which is an ideal reference surface for the inspection of instruments, precision tools, and mechanical parts. Especially for high-precision measurements, due to its unique characteristics, cast iron plates pale in comparison. Marble slabs and platforms are suitable for industrial production and laboratory measurement work. The main mineral components are pyroxene, plagioclase, a small amount of olive, biotite, and trace magnetite, with a black luster and precise structure. After billions of years of aging, it is uniform, stable, strong, and hard, and can maintain high precision under heavy loads.

The marble slabs and platforms produced by our factory are made of high-quality "Jinan Qing" natural granite material that has been mechanically processed and hand polished. Black luster, precise structure, uniform texture, good stability, high strength, and high hardness. Can maintain stability under heavy loads and normal temperatures. Granite platform is a precision reference measuring tool made of natural stone materials, which is an ideal reference surface for the inspection of instruments, precision tools, and mechanical parts, especially for high-precision measurement. Granite is made from high-quality rock layers underground, and after billions of years of natural aging, its shape is extremely stable, so there is no need to worry about deformation due to conventional temperature differences. The granite material selected through rigorous physical testing is finely crystallized and has a hard texture. Due to its non-metallic nature, granite has no magnetic reaction or plastic deformation. Its hardness is high, therefore it has good accuracy retention. Even if rock tools are hit by heavy objects during use, at most a few pieces of gravel will fall off. It is superior to precision measuring reference parts made of high-quality cast iron and steel, and can achieve high and stable accuracy. The 1000 × 630mm '00' grade marble slabs and platforms produced by our factory can still maintain their original accuracy after being put on hold for a year.
