Granite inspection platforms are benchmark measuring tools made of stone. They are ideal reference surfaces for testing instruments, tools, and mechanical components. Granite platforms are particularly suitable for high-precision measurements.
Granite inspection platforms are made from underground rock layers. After millions of years of natural aging, their shape remains stable and there is no risk of deformation due to normal temperature fluctuations. Granite platforms are made from granite materials that have undergone rigorous physical testing and selection, resulting in fine crystals and a hard texture. Because granite is a non-metallic material, it exhibits magnetic properties and exhibits no plastic deformation. The high hardness of the granite platform ensures excellent precision retention.
The long-term aging of the rock results in a uniform structure, a low linear expansion coefficient, and the elimination of internal stresses, which prevents deformation. This results in high precision. The platform also offers excellent rigidity, hardness, and wear resistance. It is resistant to acid and alkali corrosion, will not rust, requires no oiling, and is dust-resistant. It is easy to maintain and has a long service life. It won't scratch, isn't affected by constant temperature conditions, and maintains temperature measurement accuracy even at room temperature. It's non-magnetic, allowing for smooth, non-stuttering measurements and unaffected by moisture. Its surface is well-defined, and the granite platform boasts a dense microstructure, a smooth, wear-resistant surface, and a low roughness value.
The marble platform, made from marble that has undergone rigorous physical testing and selection, boasts a fine texture and a hard surface. Because marble is a non-metallic material, it exhibits no magnetic reactivity and exhibits no plastic deformation. Its primary mineral components are pyroxene, plagioclase, a small amount of olivine, mica, and trace amounts of magnetite. It boasts a black color and a fine structure, maintaining high accuracy under heavy loads.
The stone's specific gravity, compressive strength, elastic wear resistance, linear expansion coefficient, water absorption of 0.13%, and a Shore hardness of HS70 or higher are rated at 1, 0, 00, and 000 grades, respectively. It is an ideal tool for marking and inspection in processing companies.
