The unique advantages of granite precision components
Excellent stability
After billions of years of natural aging, the internal stress has long been completely eliminated, and the material is extremely stable. Compared with metal materials, metals often have residual stress in the interior after processing, and are prone to deformation with the passage of time or environmental changes. For example, in the optical lens grinding process, if a metal platform is used, its slight deformation may lead to a deviation in the lens grinding accuracy, affecting key indicators such as lens curvature. The stable structure of granite precision components can provide stable support for optical processing equipment, ensure that the relative position of each component is unchanged during processing, and ensure the processing accuracy of optical components such as lenses.
Excellent wear resistance
Granite crystal fine, hard texture, its Mohs hardness up to 6-7 (Shore hardness Sh70 or more), compressive strength up to 2290-3750 kg/cm2, hardness than cast iron 2-3 times higher (equivalent to HRC > 51). In the process of frequent use of optical instruments, such as the movement of the optical adjustment frame, the placement and taking of optical components, the surface of the granite platform is not easy to wear. On the contrary, the surface of the metal platform is prone to scratches and wear after long-term use, resulting in a decline in the flatness of the platform, affecting the installation accuracy of the optical components and the performance of the optical system.
Good thermal stability
The optical industry is extremely sensitive to temperature changes, and small temperature fluctuations may affect parameters such as refractive index and size of optical components. The linear expansion coefficient of granite is small, the effect of temperature is small, and the dimensional stability is far better than that of metal when the temperature changes. For example, in optical measuring equipment such as laser interferometers that have high environmental requirements, the metal structure is prone to thermal expansion and cold contraction due to temperature changes, resulting in a change in the length of the measurement optical path and the introduction of measurement errors. Granite precision components can effectively reduce the impact of temperature on the equipment to ensure measurement accuracy and stability.
Excellent corrosion resistance
The optical industry often involves some chemical reagents for cleaning, coating and other processes, and the humidity of the working environment also changes. Granite is acid, alkali and corrosion resistant, and will not rust and corrode like metal in wet or chemical environment. Take the optical coating workshop as an example, if the metal platform is used, the long-term contact with the volatile chemicals in the coating process, the platform surface will be corroded, which will affect the flatness and stability of the optical component placement, and ultimately affect the quality of the coating. Granite precision components can maintain stable performance in complex environments.
Application of ZHHIMG granite precision components in optical industry
Optical component machining
ZHHIMG's granite precision platform provides a stable foundation for the grinding equipment during the grinding and polishing process of optical lenses. Its high-precision flatness ensures uniform contact between the grinding disc and the lens, ensuring that the lens surface processing accuracy reaches micron or even sub-micron level. At the same time, the wear resistance of the granite platform ensures the continuous stability of the accuracy in the long-term use process, and greatly improves the yield and production efficiency of the optical lens.
Optical system assembly
In the assembly of optical systems, such as camera lenses, microscope objectives and other assembly, it is necessary to accurately align the optical components. Precision measurement components such as Granite measuring units from ZHHIMG can be used to detect the position and Angle deviation of optical components. Its stable measurement basis can help the assembly personnel accurately adjust the position of the optical components, ensure the optical axis consistency of the optical system, and improve the imaging quality of the optical system.
