Precision Marble Testing Platform

The marble platform is sourced from underground rock layers, having undergone millions of years of natural aging, ensuring an extremely stable form that is not prone to deformation due to conventional temperature variations. Subjected to rigorous physical tests and selected granite materials, the crystals are fine and the material is extremely hard, with compressive strength ranging from 2290 to 3750 kg/sq cm and a Mohs hardness of 6-7. It is highly resistant to wear, acids, and alkalis, boasting excellent corrosion resistance and will never rust. As a non-metallic material, marble has a hardness that is 2-3 times higher than cast iron (equivalent to HRC>51), resulting in excellent precision retention. During use, even if the rock tools are bumped by heavy objects, only a few stone fragments may fall off, unlike metallic tools that would deform and compromise precision. The precision measurement components made from marble, superior to those made from cast iron and steel, can achieve high and stable precision.

The precision marble testing platform utilizes natural marble material, which is mechanically processed and hand-finished. It boasts a black luster, precise structure, uniform texture, and excellent stability. It features high strength and hardness, as well as rust-proof, acid and alkali-resistant, non-magnetized, non-deformed, and good wear resistance. It maintains stability under heavy loads and general temperatures.

The Marble Platform is a precision benchmark measurement tool made from natural stone materials, serving as an ideal reference surface for the inspection of instruments, precision tools, and mechanical components. Particularly in high-precision measurement applications, its unique characteristics make cast iron plates pale in comparison.

Gabbro precision plates, gabbro inspection plates, and instrument platforms are manufactured using "Jinan Qing" stone material, processed by mechanical means and hand-finished. These plates feature a black luster, precise structure, even texture, excellent stability, high strength, and hardness. They maintain high precision under heavy loads and normal temperatures, and offer advantages such as resistance to rust, acid and alkali, wear resistance, non-magnetization, and non-deformation. Gabbro precision plates are suitable for measuring tools in machinery factories.
