        Granite/Marble is an extremely durable and robust material, widely used across various industries. Due to its excellent properties such as high corrosion resistance, wear resistance, and exceptional dimensional stability, Granite/Marble components have gained increasing popularity in the manufacturing sector in recent years. Among all applications of Granite/Marble, one of the most prevalent is in the manufacturing of bridge-type Coordinate Measuring Machines (CMM) or 3D measuring machines. This article will explore the differences in performance when using Granite/Marble components under varying environmental conditions.

Bridge-type CMMs play a crucial role in the manufacturing industry as they ensure the precision and accuracy of the produced components. The precision of CMM is largely attributed to the outstanding characteristics of Granite/Marble, which guarantees stability and accuracy. However, different environments can have varying impacts on the Granite/Marble components within CMMs.

In stable environments, such as air-conditioned rooms, the use of Granite/Marble components in CMMs provides unparalleled accuracy and precision. Granite/Marble components exhibit extremely high dimensional stability and strong resistance to vibrations and temperature fluctuations, ensuring that measurement results remain unaffected by environmental changes.

On the other hand, in unstable environments where there are fluctuations in temperature, humidity, and vibrations, the use of Granite/Marble components in CMM may negatively affect measurement accuracy. The impact of vibrations can lead to errors in measurement results, thereby influencing the quality of finished components. Additionally, temperature changes may cause Granite/Marble components to expand or contract, altering the dimensional stability of the CMM and subsequently affecting measurement accuracy and precision.

Another factor affecting Granite/Marble components used in CMM is the presence of dust and dirt. The accumulation of dust on the surface of Granite/Marble can alter friction values, reducing the accuracy of measurement results. Furthermore, dirt may cause surface wear on Granite/Marble components, affecting the durability of the CMM.

In conclusion, the use of Granite/Marble components in CMM provides extremely high precision and accuracy, making them an indispensable part of the manufacturing industry. Under stable environmental conditions, Granite/Marble components ensure precise and accurate measurement results. However, under unstable environmental conditions, such as fluctuations in vibrations and temperature, the accuracy of CMM may be negatively impacted. Therefore, to maintain a high level of precision and accuracy when using Granite/Marble components in CMM, it is essential to consider environmental conditions and take necessary measures to ensure environmental stability.
