1. The Shore hardness of granite is 108, which is 3 times that of cast iron, and the wear resistance is 20 times that of cast iron. The compressive strength is 2290-3750 kg/cm2. It is resistant to abrasion, acid, alkali, and corrosion, and does not deform under heavy pressure.
-
2. Granite’s coefficient of linear expansion is one-third of that of cast iron, and the thermal stability is 20 times that of cast iron. Its thermal deformation is very little.
-
3. The damping coefficient (the ability to prevent and absorb vibration) of granite is 10 times larger than that of cast iron, and it is all solid, with good ability of shock absorption. From experiments, it has proved that the use of granite machine bed, gantry, machine bed and other machine tools can increase the surface accuracy of workpieces by 30%, and the tool durability can be improved by 37%.
-
4. Unlike metallic materials, granite doesn’t have plastic deformation nor magnetic reaction. Granite has good rigidity and physical properties.
-
5. Granite doesn’t rust. It’s easy to maintain and has longer service life. Stone processing has low energy consumption, no pollution. The material is derived from nature. It is eco-friendly and has high social benefits.
Frequently Asked Questions
What are the main advantages of using a granite vacuum table?
Granite vacuum tables offer exceptional flatness, high accuracy, a low coefficient of linear expansion, and superior wear resistance. They feature micro holes and air flow channels with a non-deforming clamping surface, making them ideal for optics, soft materials, thin work, and panel manufacturing.
How does the hardness and wear resistance of granite compare to cast iron?
Granite has a Shore hardness of 108, which is 3 times that of cast iron, and its wear resistance is 20 times higher. With a compressive strength of 2290-3750 kg/cm², granite resists abrasion, acid, alkali, and corrosion without deforming under heavy pressure.
Why is granite considered thermally stable for machinery components?
Granite's coefficient of linear expansion is only one-third of that of cast iron, and its thermal stability is 20 times higher. This ensures extremely minimal thermal deformation under varying temperature conditions.
Can a granite machine bed improve workpiece and tool performance?
Yes. Because granite has a vibration damping coefficient 10 times larger than cast iron, it absorbs shock efficiently. Experiments show that using granite beds and gantries can improve workpiece surface accuracy by 30% and tool durability by 37%.
Does granite rust or react magnetically?
Unlike metallic materials, granite does not rust, has no magnetic reaction, and does not undergo plastic deformation. It retains high rigidity, requires low maintenance, and provides a long service life.
Is granite an environmentally friendly material choice?
Yes. Granite is derived directly from nature. Its processing requires low energy consumption and produces no pollution, making it an eco-friendly choice with high social benefits.
