When looking for precision positioning equipment, there are several options available on the market. Among them, granite and metal are two commonly used materials. However, for Granite Air Bearing Stage products, granite is often chosen over metal. Why do people choose granite over metal for these products? Here are some reasons why:
1. Stability and durability
Granite is known for its stability and durability, which makes it an excellent material for air bearing stage products. These products require a high level of precision, and any slight variations or vibrations can cause inaccuracies and errors. Granite, being a natural stone, is dense and stable, which greatly reduces the chances of any oscillation or movement, ensuring a stable, vibration-free platform that can withstand rigorous use.
2. Corrosion resistance
In some applications, the air bearing stage products may be exposed to corrosive elements. Metals such as iron and steel, which are commonly used in machinery, can rust and corrode over time when exposed to moisture and chemicals that can cause damage to the products. Unlike metal, granite is non-porous and does not rust or corrode, making it a reliable choice for applications that require long-term and reliable performance.
3. High precision
The granite used in air bearing stage products is often polished to achieve high precision. The polishing process makes the surface of the granite flat and smooth, allowing for a high degree of geometric accuracy and dimensioning. The accuracy that granite offers is unmatched in metal, which can be affected by temperature changes and machine-tool deformations over time.
4. Low friction
Air bearing stage products rely on air bearings to achieve frictionless movement. This allows for greater control and precision when positioning objects. With the low friction coefficient of granite compared to other materials like metal, such as steel or aluminum, it reduces the amount of wear and tear on these components and eliminates any chance of surface pitting that would eventually lead to uneven movement.
In conclusion, granite is an excellent choice for air bearing stage products due to its high stability, durability, corrosion resistance, high precision, and low friction. While metal may be a suitable material for a variety of applications, the superior precision and long-term performance that granite provides make it the favored material for air bearing stage products.
