The granite measuring devices and granite mechanical components are made of high quality Jinan Black granite. Due to their high precision, long duration, good stability and corrosion resistance,  They have been more and more used in products inspection of modern industry and such scientific areas as mechanical aerospace and scientific researches. 

Physical property of Jinan Black Granite: 

Specific gravity: 2970-3070 kg/CBM

Compressive Strength: 245-254 Mpa

Elastic Modulus: 30-50 Gpa

Linear Expansion Coefficient: 4.61 x 10 -6/0 C 

Water Absorptivity:  0.07

Shore Hardness: Above 70Hs

The products have the following characteristics: 

1. High precision, reliable stability resistant to deform and guaranteed accuracy under normal ambient temperature. 

2. No-rust and anti corrosion

3. Wear resistance long service life

4. Any cutting or scratching for working surface does not bring about rough edges which might influence its measuring precision

5. Non magnetization

6. Glossy surface without sluggishness when the workpieces or tools are moving on it

For inspection machine spindle and else squareness work-pieces.
