Granite marking platform product alias: marble tablet, marble workbench, granite tablet, granite platform, granite tablet, granite platform.

Marble Marking Plate, Marble Marking Platform Introduction: Marble plates and marble workbenches are made from underground rock layers and 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 damaging, acid resistant, alkali resistant, highly resistant, and will not rust. Due to its non-metallic nature, marble exhibits magnetic reactivity and does not undergo 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 cast iron and steel, and can achieve high and stable accuracy.

Marble slabs and marble workbenches are made from marble materials that have been mechanically processed and finely ground by hand. Black luster, precise structure, uniform texture, and good stability. High strength and hardness. And it has the advantages of no rust, no magnetization, no deformation, and good quality. Can maintain stability under heavy loads and normal temperatures.

Marble tablet (marble workbench) is a precision reference measuring tool made of stone material, which is an ideal reference surface for the inspection of instruments, precision tools, and mechanical parts. Especially for high-precision measurements, due to its characteristics, cast iron plates pale in comparison. Marble slabs and marble workbenches 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 marble workbenches produced by our factory are made of "Jinan Qing" granite material that has been mechanically processed and finely ground by hand. Black luster, precise structure, uniform texture, good stability, high strength, and high hardness. Can maintain stability under heavy loads and normal temperatures. The granite marking platform is a precision reference measuring tool made of stone material, 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 underground rock layers and has undergone billions of years of natural aging, resulting in an extremely stable shape without worrying 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 exhibits magnetic reactivity and no 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 measurement reference parts made of cast iron and steel, and can achieve high and stable accuracy. The 1000 × 630mm '00' grade marble slabs and marble workbenches produced by our factory can still maintain their original accuracy after being put on hold for a year.

Characteristics and advantages of marble slab (marble workbench):

After long-term aging, the rock has a uniform organizational structure, linear expansion coefficient, disappearance of internal stress, and no deformation, resulting in high accuracy.

Good rigidity, high hardness, and strength.

Not afraid of acid and alkali erosion, will not rust, does not need to be oiled, is not easy to stick to dust, easy to maintain, and has a long service life.

No scratches, not hindered by constant temperature conditions, and able to maintain temperature measurement accuracy at room temperature.

Non magnetized, able to move smoothly during measurement, without any sluggishness, not affected by moisture, and the plane is properly weighed.
