The granite precision instrument platform is made of high-quality “Jinan green” stone material through mechanical processing and manual precision grinding. High precision, no deformation, good stability, long service life, suitable for measurement work in mechanical factories and laboratories.
The main mineral components of “Jinan Qing” granite are pyroxene, plagioclase, biotite, and trace amounts of magnetite. It has a black color, precise structure, and has undergone billions of years of aging. Its texture is uniform, stable, strong, and hard, and it can maintain high precision under heavy loads.
Avantages :
1. High precision, good stability, and resistance to deformation, ensuring measurement accuracy at room temperature.
2. No rust, acid and alkali resistant, no need for special maintenance.
3. Good wear resistance and long service life.
4. Scratches and bumps on the work surface do not affect measurement accuracy
5. There is no magnetization issue.
6. Smooth sliding during measurement without any sluggishness
