Detailed Product Description: | Granite slab: precision reference measurement tools, natural stone material, for instruments, precision tools, machinery parts of the test, it is an ideal base, granite platform: high precision, no rust, acid, non-magnetized, the same type, and good abrasion resistance. Granite platform based on the quality of the rock layers underground, after millions of years of natural aging, form extremely stable, do not worry because the conventional temperature and deformation. Granite platform through rigorous physical testing and selection of granite materials, crystal fine, hard texture. Because granite-based non-metallic materials, no magnetic response, no plastic deformation. Granite slab using a high-precision electronic levels detected at 20 ℃ ± 2 ℃ constant temperature and 50% humidity. We can also be drilled, glued parts according to customer's drawings, open T-slot, groove, dovetail so on. General precision surface can exceed the achievable accuracy of other material, non-corrosive, no maintenance. Granite slab physical properties: flatness tolerance according to: GB4987-85 Standard: 000 = 1 × (1 + d / 1000) um 00 级 = 2 × (1 + d / 1000) um 0 级 = 4 × (1 + d / 1000) um 级 1 = 8 × (1 + d / 1000) um (d diagonal mm) (measured temperature is generally 20 ± 2 ℃ granite slab proportion: 2970 -3070kg / m compressive strength : 245-254N / m linear expansion coefficient: 4.61 × 10-6 / ℃, water absorption: <0.13% Shore Hardness: Hs70 above |
