Granite Plate Advantages
- Aug 28, 2018 -

Natural granite materials are machined and hand-finished. Black gloss, precise structure and good stability. High strength and high hardness. And has: no rust, acid and alkali resistance, non-magnetization, invariable type, good wear resistance and so on. It can be stable under heavy load and normal temperature.

Granite slab, precision granite slab, granite inspection slab, instrument platform, made of high-quality "Jinan Green" stone by mechanical processing and hand-finishing. Black gloss, precise structure, uniform texture, good stability, high strength, high hardness, high precision under heavy load and normal temperature, and no rust, acid and alkali resistance, wear resistance, non-magnetization, invariable Advantages. Granite plates are suitable for measuring tools in machinery factories.

The granite slab is a precision reference measuring tool made of natural stone materials. It is an ideal datum for inspection of instrumentation, precision tools and mechanical parts. Especially for high-precision measurement, due to its unique characteristics, the cast iron plate is dwarfed. Granite is made from high-quality underground rock layers. After hundreds of millions of years of natural aging, the shape is extremely stable, so you don't have to worry about deformation due to the normal temperature difference. Through strict physical tests and selected granite materials, the crystals are fine and hard, the compressive strength is 2290-3750 kg/cm 2 and the hardness is 6-7. Extremely resistant to abrasion, acid and alkali, high corrosion resistance and never rust. Due to the non-metallic materials of granite, there is 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 is good. In use, even if the rock tool is hit by a heavy object, at most a few stones are removed, and the precision is not destroyed by deformation like a metal tool. It is superior to precision measuring reference parts made of high quality cast iron and steel for high and stable accuracy.
