Overview

Granite/marble components have high hardness and are relatively difficult to process. Traditionally, rough stone materials are sawed and drilled, and then polished multiple times to achieve a mirror like luster. This method is time-consuming and labor-intensive, but it has the characteristics of precision, stability, and easy maintenance.

Product Details

Granite/marble componentsDerived from high-quality underground rock layers, after billions of years of natural aging, the shape is extremely stable, and there is no need to worry 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/square centimeter, 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 exhibits magnetic reactivity and no plastic deformation. Its hardness is 2-3 times higher than cast iron (equivalent to HRC>51), therefore 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.

Granite/marble componentsThe hardness is very high and the processing is quite complicated. Traditionally, the rough stone material is sawed and punched, and then polished multiple times to achieve a mirror like luster, which is time-consuming and labor-intensive. However, it has the characteristics of precision, stability, and easy maintenance. Due to its high precision and stable physical performance, it is often used as a testing platform and can also be used as a basic workbench for high-precision optical instruments.
