Granite machinery beds and components
Our lightweight and compact modular active vibration isolation systems counteract the vibrations that affect sensitive equipment. The streamlined design allows easy installation requiring no follow-up tuning. Developed by engineers, physicists and leading industry consultants with expertise in precision instruments, ISO-Mod-A is a revolutionary device that plays an essential role in reducing vibrations and disturbances.
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 benefits of using a granite vacuum table?
Granite vacuum tables offer exceptional flatness and accuracy, a low coefficient of linear expansion, and high wear resistance. They provide a flat clamping surface that prevents the deformation of workpieces, making them ideal for optics, soft materials, thin work, and panel manufacturing.
How hard and wear-resistant is granite compared to cast iron?
Granite has a Shore hardness of 108, which is 3 times harder than cast iron, and its wear resistance is 20 times higher. It has a compressive strength of 2290-3750 kg/cm2, resisting abrasion, acid, alkali, and corrosion without deforming under heavy pressure.
Does granite deform easily with temperature changes?
No, granite's coefficient of linear expansion is only one-third of that of cast iron, and its thermal stability is 20 times higher. This means its thermal deformation is extremely minimal under temperature fluctuations.
How does a granite machine bed improve machining accuracy?
The damping coefficient of granite is 10 times larger than that of cast iron, providing superior shock absorption. Experiments show that using a granite machine bed or gantry can increase the surface accuracy of workpieces by 30% and improve tool durability by 37%.
Is granite environmentally friendly and easy to maintain?
Yes, granite does not rust, is easy to maintain, and has a longer service life because it has no plastic deformation or magnetic reaction. Additionally, stone processing has low energy consumption, produces no pollution, and uses natural materials, making it highly eco-friendly.
