High precision
Excellent flatness: After fine processing, granite can obtain extremely high flatness. Its surface flatness can reach micron or higher accuracy, providing a stable, horizontal support benchmark for precision equipment, ensuring that the equipment maintains high precision positioning and movement during operation.
Good dimensional stability: Granite has a very low coefficient of thermal expansion and is very little affected by temperature changes. In different ambient temperatures, the size change is very small, can effectively maintain the accuracy of the equipment, especially suitable for temperature sensitive precision machining and measurement occasions.
High rigidity and strength
Excellent bearing capacity: Granite has a high density and hardness, with strong compressive strength and bending strength. It can withstand heavier equipment and workpieces without obvious deformation, ensuring the stability and reliability of equipment operation.
Strong vibration resistance: the internal structure of granite is dense and uniform, and has good damping characteristics, which can effectively absorb and attenuate vibration energy. This allows the equipment installed on the granite precision base to maintain stable operation in a more complex vibration environment, reducing the impact of vibration on machining accuracy and measurement results.
Good wear resistance
Not easy to wear: Granite has high hardness and good surface wear resistance. In the long-term use process, even if subjected to a certain degree of friction and wear, its surface accuracy can be better maintained, thus extending the service life of the base and reducing the maintenance cost of the equipment.
Good surface quality retention: Because granite is not easy to wear, its surface can always remain smooth and delicate, which is conducive to improving the motion accuracy and stability of the equipment, but also easy to clean and maintain, reducing the dust accumulation and impurity adsorption caused by the rough surface.
Corrosion resistance
High chemical stability: Granite has good chemical stability and is not easy to be eroded by acid, alkali and other chemical substances. In some harsh working environments, such as places where corrosive gases or liquids exist, granite precision base can maintain its performance and accuracy without being affected, and has a long service life.
Low water absorption: The water absorption of granite is low, which can effectively prevent water from penetrating into the interior and avoid problems such as expansion, deformation and corrosion caused by water. This feature allows the granite precision base to be used normally in wet environments or in situations where cleaning is required.
Environmentally friendly non-magnetic
Green environmental protection: Granite is a kind of natural stone, does not contain harmful substances, no pollution to the environment. In modern industrial production, which focuses on environmental protection, this feature makes granite precision base an ideal choice.
Non-magnetic interference: Granite itself is not magnetic, will not produce magnetic interference on precision instruments and equipment. This is essential for some magnetic field sensitive equipment, such as electron microscopes, nuclear magnetic resonance meters, etc., to ensure the normal operation of the equipment and the accuracy of the measurement results.
