Marble platform

Marble platforms are also called granite slabs, marble slabs, granite platforms. Like other marble square feet products, the main mineral components are pyroxene, plagioclase, a small amount of olivine, biotite and trace magnetite, black. Gloss, precise structure, uniform texture after millions of years of aging. Sales Hotline (0317-8175168).

Marble platform details

The marble platform is made of "Jinan Qing" granite, which is machined and refined by hand. Black gloss, precise structure and uniform texture, good stability. High strength and high hardness. And has the advantages of: non-rust, acid and alkali resistance, non-magnetization, invariance, good abrasion resistance, etc., can maintain stability under heavy load and general temperature.
The marble platform (marble slab) has undergone rigorous physical tests and selected granite materials, with fine crystals and hard texture, compressive strength of 2290-3750 kg / cm2, and hardness of 6-7 Mohs. Extremely resistant to abrasion, acid and alkali, has high corrosion resistance and will not rust. Because granite is a non-metallic material, 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 maintained.
(大理石平板)是用石质材料制成的精密基准测量工具,对仪器仪表、精密工具、机械制件的检验,都是理想的基准面。 The marble platform (marble slab) is a precision reference measuring tool made of stone materials. It is an ideal reference surface for the inspection of instruments, precision tools and mechanical parts. Especially for high-precision measurement, cast-iron flat plates are dwarfed by its unique characteristics. Granite is taken from the underground rock layer. After hundreds of millions of years of natural aging, its shape is extremely stable, so you don't have to worry about deformation due to conventional temperature differences.
Granite platform accuracy reference standard, flatness tolerance according to: GB4987-85 standard:
Level 000 = 1 × (1 + d / 1000) um
00 level = 2 × (1 + d / 1000) um
Level 0 = 4 × (1 + d / 1000) um
Level 1 = 8 × (1 + d / 1000) um
(D is the diagonal mm) (The measurement temperature is generally 21 ± 2 ℃
Marble slab characteristics and advantages:
1. After long-term aging, the structure of the rock is uniform, the coefficient of linear expansion is very small, the internal stress disappears, and it is not deformed, so the accuracy is high.
2. Good rigidity, high hardness and strong wear resistance.
3, not afraid of acid, corrosive liquid erosion, will not rust, do not need oiling, not easy to stick to dust, maintenance, easy and simple maintenance, long service life.
4, no scratches, not blocked by constant temperature conditions, can maintain the temperature measurement accuracy at room temperature.
5, non-magnetized, can move smoothly during measurement, no stagnation, and not affected by humidity, the plane scale is good.
