The importance of material selection
Precision granite components, as key components in industrial manufacturing, their accuracy, stability and durability are crucial. Therefore, when selecting the granite material used to make these components, it is necessary to consider many factors such as hardness, wear resistance, corrosion resistance, coefficient of thermal expansion and internal stress state. These factors will directly affect the machining accuracy, service life and performance of the components in various working environments.
Jinan Qing: the first choice for precision components
Among the many granite varieties, Jinan Green stands out with its excellent performance and has become the preferred material for the production of precision granite components. Jinan blue granite is famous for its fine grain structure, uniform texture and extremely low internal stress. These characteristics enable Jinan Green to maintain extremely high accuracy and stability in the processing process, while it is not easy to produce deformation and wear during use.
The advantages of Jinan green
1. High hardness and wear resistance: The Mohs hardness of Jinan blue granite is as high as 6-7, and the wear resistance is excellent. This allows the precision components made of Jinan Green to maintain stable accuracy and shape for a long time in a high-load, high-friction working environment.
2. Low coefficient of thermal expansion: Compared with other stone materials, Jinan Green has a lower coefficient of thermal expansion. This means that in the working environment with large temperature changes, the components made of Jinan green are not easy to deform due to thermal expansion and cold contraction, thus ensuring the accuracy and stability of the measurement.
3. Small internal stress: Jinan blue granite has experienced a long time of natural weathering and geological processes in the formation process, and the internal stress has been fully released. This makes it difficult to crack or deform due to stress concentration during processing and use.
4. Strong corrosion resistance: Jinan green has strong resistance to acid, alkali and other chemicals, and is not easy to be corroded. This feature enables the precision components made of it to maintain stable performance in a variety of harsh working environments.
Practical application and prospect
Due to the above advantages of Jinan blue granite, it has been widely used in precision measuring instruments, CNC machine tools, mold testing and other fields. In these fields, Jinan Qing precision components have won wide recognition in the market for their excellent accuracy, stability and durability. With the continuous progress of science and technology and the continuous improvement of industrial manufacturing level, the application field of Jinan Qing precision components will continue to expand and deepen.
In short, Jinan Green as the preferred material for the production of precision granite components, with its excellent performance and wide application prospects, will play a more important role in the future industrial manufacturing.
