Technical parameters and standards of granite mechanical base。

 

Granite has long been recognized as a premier material for mechanical bases due to its exceptional properties, including high density, rigidity, and resistance to thermal expansion. Understanding the technical parameters and standards associated with granite mechanical bases is crucial for engineers and manufacturers who rely on precision and durability in their applications.

One of the primary technical parameters of granite mechanical bases is its compressive strength, which typically ranges from 100 to 300 MPa. This high compressive strength ensures that granite can withstand significant loads without deformation, making it ideal for supporting heavy machinery and equipment. Additionally, granite exhibits low thermal expansion coefficients, generally around 5 to 7 x 10^-6 /°C, which minimizes dimensional changes due to temperature fluctuations, ensuring consistent performance in various environments.

Surface flatness is another critical standard for granite mechanical bases. The flatness tolerance is often specified in micrometers, with high-precision applications requiring tolerances as tight as 0.005 mm per meter. This level of precision is essential for applications such as coordinate measuring machines (CMMs) and optical devices, where even the slightest deviation can lead to significant measurement errors.

Moreover, the density of granite typically ranges from 2.63 to 2.75 g/cm³, contributing to its stability and vibration-damping properties. These characteristics are vital in reducing the impact of external vibrations, thereby enhancing the accuracy of sensitive instruments mounted on granite bases.

In conclusion, the technical parameters and standards of granite mechanical bases play a pivotal role in their application across various industries. By adhering to these specifications, manufacturers can ensure the reliability and performance of their equipment, ultimately leading to improved operational efficiency and precision in manufacturing processes. As technology advances, the demand for high-quality granite mechanical bases will continue to grow, underscoring the importance of understanding these technical standards.
