Granite vacuum table
The professional machines can be fully supplied with granite vacuum tables with excellent flatness and accuracy, low coefficient of linear expansion and high wear resistance.
-
1. Granite machine table with micro holes and air flow channels.
-
2. Flat clamping surface does not deform work pieces. Great for optics, soft materials, thin work, and panel manufacturing, processing and inspection.
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
Granite vacuum tables offer excellent flatness, extreme accuracy, a low coefficient of linear expansion, and high wear resistance, making them ideal for precision operations.
Granite has a Shore hardness of 108, which is 3 times that of cast iron, and its wear resistance is 20 times higher. It resists deformation under heavy pressure with a compressive strength of 2290-3750 kg/cm2.
