Granite platform

The granite platform is made of "Jinan Green" stone material through mechanical processing and manual precision grinding; Black luster, structure, uniform texture, good stability, high strength, can be maintained under heavy load and general temperature, and has the advantages of non rusting, non magnetization, and non deformation; The granite platform is suitable for measuring tools in mechanical factories.

Physical properties of granite platform: specific gravity: 2970-3070kg/㎡ compressive strength: 245-254N/m ㎡ strength abrasion: 1.27-1.47N/m ㎡ linear expansion coefficient: 4.6 × 10-6 ℃ water absorption rate: 0.13% Shore strength: HS70 or above.

The main mineral components of the stone are pyroxene, plagioclase, a small amount of olivine, biotite, and trace magnetite. It has a black luster, structure, and has undergone billions of years of aging, with uniform texture, good stability, high strength, and can be maintained under heavy loads; Suitable for industrial production and laboratory measurement work.

Platform debugging method:

1. Place the platform flat on the ground, adjust the stability of the four corners by hand, and fine tune the movable feet until stable.

2. Place the tablet on the bracket and adjust its pivot position to be as close to the center symmetry as possible.

3. Adjust each foot initially to ensure even force distribution at each pivot point.

4. Use a level measuring instrument (such as a spirit level or electronic spirit level) to check the horizontal condition of the tablet and adjust the relevant pivot points until they meet the horizontal position.

After the initial adjustment is qualified, let it stand for 12 hours before copying. If it is unqualified, it needs to be adjusted again. If it is qualified, it can be used.

6. After use, conduct periodic testing and maintenance based on the actual on-site environment.
