Granite Surface Plate

Technical Parameter

The main mineral components of Granite Surface Plates are pyroxene, plagioclase, a small amount of olivine, biotite, and trace magnetite. They have a black color, precise structure, no rust, acid and alkali resistance, no magnetization, no deformation, good wear resistance, and can maintain stability under heavy loads and general temperatures.

Granite Surface Plates can be divided into granite inspection platforms, granite testing platforms, granite mechanical components, etc. according to their functions.

Granite Surface Plates are used in industries such as machinery, electronics, mold processing, aerospace, and equipment manufacturing.

Granite Surface Plate manufacturing standard: GB/T 20428-2006.

Inspection standard for Granite Surface Plates: JJG 117-2013

Workface hardness: Shore 70 or above

Granite Surface Plate material: natural granite (G654 sesame black, G3701 Jinan green)

Accuracy level: Level 0, Level 00, Level 000

Granite Surface Plate specific gravity: 2970-3070kg/㎡

Compressive strength: 245-254N/m

Linear expansion coefficient: 4.61 × 10-6/℃

Water absorption rate: 1% -3%

Processing technology: It is manually ground in a constant temperature chamber to ensure product accuracy.

Granite Surface Plate product specifications: 200 * 300mm -3000 * 6000mm (note: stock specifications are 2000 * 3000mm, customized if exceeding this specification). Large Granite Surface Plates can be used by splicing multiple pieces together.

Debugging method for Granite Surface Plate:

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 level) to check the horizontal condition of the tablet and fine tune the relevant pivot points,

Until it conforms to 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 needs to be adjusted again

Only then can it be used.

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