Granite mechanical components have the following characteristics
1. High precision reliable stability resistant to deform and guaranteed accuracy under normal ambient temperature.
2. No rust and anticorrosion, no special maintenance.
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.
