Introduction:If you encounter any questions while using the granite platform, you can directly inquire with the Quanyi manufacturer, and we will have professional technicians explain it to you for free.

Granite platform is a precision reference measuring tool made of natural stone materials, which is an ideal reference surface for the inspection of instruments, precision tools, and mechanical parts. Marble platform(Granite platform) Especially used for high-precision measurement. Granite is made from high-quality rock layers underground, and after billions of years of natural aging, its shape is extremely stable, so there is no need to worry about deformation due to conventional temperature differences. The granite platform has undergone rigorous physical testing and selection of granite materials, which are finely crystallized and have a hard texture. Due to its non-metallic nature, granite has no magnetic reaction or plastic deformation. The marble platform has high hardness, therefore it has good precision retention.

In useMarble platformEven if the granite platform is hit by heavy objects, at most a few pieces of gravel will fall off. Marble platform (granite platform) is superior to precision measurement reference parts made of high-quality cast iron and steel, and can achieve high and stable accuracy. The 1000 × 630mm '00' grade rock slab produced by our company can still maintain its original accuracy after being stored for one year.

The main mineral components of granite platforms are pyroxene, plagioclase, a small amount of olivine, biotite, and trace amounts of magnetite. They have a black luster, precise structure, uniform texture, good stability, high strength, and high hardness after billions of years of aging, and can maintain high precision under heavy loads. Used for industrial production and laboratory measurement work.

Characteristics and advantages of granite platform (granite slab):

1. Rocks undergo long-term natural aging, with uniform organizational structure, extremely low coefficient of linear expansion, complete disappearance of internal stress, and no deformation, resulting in high accuracy.

2. Good rigidity, high hardness, and strong wear resistance.

3. Not afraid of acid and alkali erosion, will not rust, does not need to be oiled, is not easy to stick to dust, easy to maintain, and has a long service life.

4. No scratches, not hindered by constant temperature conditions, and able to maintain temperature measurement accuracy at room temperature.

5. Non magnetized, able to move smoothly during measurement, without any sluggishness, not affected by moisture, and the plane is properly weighed.

　The newly made rock slab should be labeled with the manufacturer's name (or logo), accuracy level, specifications, and number. The rock slab working face should have uniform color, no cracks, dents, or loose tissue, and should not have scratches, abrasions, burns, or other defects that affect the accuracy of the slab. The tablet in use is allowed to have the above-mentioned defects that do not affect accuracy. The depressions or corners that appear on the rock slab working face are not allowed to be repaired. The verification method adopts visual observation and testing. Requirements and methods for surface roughness verification of flat working surfaces and side surfaces. The surface roughness of non scraped cast iron flat working surfaces and side surfaces should comply with the provisions in the table below
