In the field of modern precision measurement, the length measuring machine, as a key device, has extremely high requirements for accuracy and stability. Granite components, with their unique advantages, have become an ideal choice for length measuring machines, especially excelling in seismic performance.
From the perspective of material properties, granite is an igneous rock formed by the close combination of various mineral crystals. The internal mineral particles are interwoven with each other, forming an extremely dense structure. This dense structure endows granite with extremely high rigidity and strength, enabling it to maintain a stable form in complex working environments. When external vibrations occur, granite components can effectively resist deformation by relying on their own rigidity, reducing the interference of vibrations on the measurement accuracy of the length measuring machine. For instance, in some industrial production workshops, the frequent start and stop of surrounding equipment can cause vibrations. The components of the length measuring machine made of ordinary materials are prone to slight displacement or deformation due to vibrations, which in turn affects the measurement results. However, due to its rigidity advantage, granite components can minimize this impact.
The high damping characteristic of granite is one of the key factors for its superior seismic performance. Damping refers to the ability of a material to consume energy and reduce the amplitude of vibration during the vibration process. The damping ratio of granite is much higher than that of many metal materials and other common stones. When the vibration is transmitted to the granite component, the crystal structure inside it can convert the vibration energy into other forms of energy such as thermal energy and dissipate it rapidly. This is just like installing an invisible shock absorber on the length measuring machine, which can quickly attenuate the vibration and enable the length measuring machine to quickly return to a stable state in a vibrating environment. Take the precision mechanical processing workshop as an example. The high-speed operation of machine tools will generate strong vibrations. If the length measuring machine uses granite components, it can still maintain stable measurement in such an environment and ensure the accuracy of the measurement data.
Compared with other materials, granite components have obvious advantages in terms of earthquake resistance. Although metallic materials have high strength, their damping performance is often poor. When subjected to vibration, they tend to generate continuous oscillations that are difficult to subside quickly. While some synthetic materials may have certain shock absorption effects, they cannot compare with granite in terms of rigidity and long-term stability. Granite components perfectly combine the characteristics of high rigidity and high damping. They can not only maintain the integrity of the structure when vibration occurs, but also quickly suppress the spread and persistence of vibration.
In practical applications, length measuring machines using granite components have demonstrated outstanding performance in numerous fields. In the manufacturing of aerospace components, high-precision length measuring machines are crucial for ensuring the accuracy of component dimensions. The seismic performance of granite components enables the length measuring machine to work stably in complex workshop environments, providing a solid guarantee for the quality control of aerospace parts. In the field of optical instrument manufacturing, the dimensional measurement accuracy of precision optical components such as lenses directly affects the imaging quality of the instrument. The application of granite components effectively reduces the interference of external vibrations on measurement, helping optical instrument manufacturing achieve higher precision.
Granite components, with their excellent seismic performance, have become the core element for length measuring machines to enhance measurement accuracy and stability. With the continuous development of precision measurement technology, the application prospects of granite components in length measuring machines and more precision measurement equipment will be even broader, continuously providing reliable support for high-precision manufacturing in various industries.
