Why choose granite as the material of gas bearing of CNC equipment?

In recent years, CNC equipment has become an important tool in manufacturing and production. It requires precise movements and stability, which is only possible with the use of high-quality materials for its components. One such component is the gas bearing, which is used to support and guide the rotating parts. The material used for the gas bearing is crucial, and granite has emerged as a popular choice for this purpose.

Granite is a type of natural stone that has been used for various applications for centuries. It is known for its durability, strength, and ability to withstand extreme temperatures and pressures. These qualities make it an ideal material for gas bearings in CNC equipment.

Firstly, granite has excellent thermal stability. The heat generated during the CNC machining process can cause significant expansion and contraction of the components, which can affect the accuracy of the equipment. Granite's high thermal stability ensures that it does not expand or contract significantly, maintaining the accuracy of the equipment.

Secondly, granite is known for its high stiffness and low coefficient of thermal expansion. This means that it does not deform easily under pressure, providing stable and reliable support to the moving parts of the equipment. The low coefficient of thermal expansion also means that granite does not expand or contract significantly with temperature changes.

Thirdly, granite has a low coefficient of friction, which means that it reduces wear and tear on the moving parts of the equipment. This leads to longer service life and reduced maintenance cost.

Finally, granite is easy to machine and can be polished to a high precision. This makes it an ideal material for gas bearings in CNC equipment since precision and accuracy are crucial for the proper functioning of the equipment.

In conclusion, granite is an excellent choice of material for gas bearings in CNC equipment. Its high thermal stability, stiffness, low coefficient of thermal expansion, low coefficient of friction, and ease of machining make it an ideal material for this purpose. Using granite gas bearings for CNC equipment can significantly improve the accuracy, reliability, and service life of the equipment.
