Material introduction of granite precision surface plate: Accuracy is divided into 0 grade according to user requirements. 00 level. The granite plate has undergone rigorous physical tests and selected granite materials, with fine crystals and hard texture. Because granite is a non-metallic material, it has no magnetic reaction and no plastic deformation. The granite slab has high hardness, so the accuracy retention is good. Taken from underground high-quality rock layers, after hundreds of millions of years of natural aging, the shape is extremely stable, so there is no need to worry about deformation due to conventional temperature differences. The granite slab has undergone rigorous physical tests and selected granite materials, with fine crystals and hard texture. Because granite is a non-metallic material, it has no magnetic reaction and no plastic deformation. The granite slab has high hardness, so the accuracy retention is good.

It won’t be a few grains of stone dropped even if the rock tool is hit by a heavy object. The granite slab is superior to precision measurement reference parts made of high-quality cast iron and steel, and can obtain high and stable accuracy. The granite slab is a precision reference measurement tool made of natural stone materials. It is an ideal reference surface for the inspection of instruments, precision tools, and mechanical parts. Especially for high-precision measurement, due to its unique characteristics, cast iron flat plates are indistinguishable. Extremely resistant to abrasion, acid, alkali, high corrosion resistance, and will never rust. Because granite is a non-metallic material, it has no magnetic reaction and no plastic deformation. Its hardness is 2-3 times higher than that of cast iron (equivalent to HRC>51), so the accuracy retention is good. In use, even if the rock tool is hit by a heavy object, at most a few grains of ballast will be dropped, and the accuracy will not be destroyed by deformation like a metal tool. It is superior to precision measurement reference parts made of high-quality cast iron and steel, and can obtain high and stable accuracy. It is suitable for industrial production and laboratory measurement work.
