As precision instruments, coordinate measuring machines (CMMs) require a stable and reliable system to ensure accurate and consistent measurements. One of the key components that guarantee long-term stability in a CMM is the use of granite material.
Granite is an ideal material for CMMs because of its characteristics. It is an igneous rock with high thermal stability, low thermal expansion, low moisture absorption, and high stiffness. These qualities make it an extremely stable material that can withstand temperature changes, vibrations, and other environmental factors that could affect the accuracy of the measurements.
Temperature stability is an important factor in CMMs. The granite material used in CMMs has a low coefficient of thermal expansion, meaning that it is less susceptible to thermal expansion and contraction due to changes in temperature. Even when the temperature changes, granite maintains its shape and size, ensuring that the measurements remain accurate.
The stiffness of granite also plays a vital role in the stability of CMMs. It is a very hard and dense material, which means that it can support a heavy load without deforming or bending. The stiffness of granite creates a rigid structure that provides a stable platform for the machine. Therefore, it reduces the possibility of deformation when using the CMM, even when placing heavy objects.
Aside from physical stability, granite also resists chemical and moisture damage, which helps prolong its lifespan. It is not affected by moisture and hence will not rust, corrode or warp, which could affect the measurements in a CMM. Granite is also resistant to most chemicals and does not react with them. Therefore, it is unlikely to be damaged by substances such as oils and other solvents commonly used in a manufacturing environment.
In conclusion, the use of granite in CMMs is crucial for long-term stability and accuracy. Its unique properties make it an ideal material for the construction of the base, measuring platform, and other important components of a CMM. CMMs made with granite have high precision, reliability, and repeatability, promote the quality of production processes, and enhance overall manufacturing efficiency. Notably, granite delivers unparalleled environmental durability, making it the perfect material for use in various kinds of applications.
