What are the applications of Wulianhua in precision instruments?

Wulianhua granite will not be damaged even if it is hit by heavy objects. Wulianhua granite is superior to high-quality standard parts made of cast iron and steel, and can obtain high and stable accuracy. After a long period of natural aging, the arrangement of rocks is very uniform, the linear expansion coefficient is small, the internal stress disappears completely, and it is not easy to deform, so the accuracy is very high. Good rigidity, high hardness and strong wear resistance. Not afraid of acid, alkali and liquid corrosion, no rust, no oiling. At the same time, it is not easy to stick ash, convenient and simple to protect and maintain, and has a long service life. There will be no scratches and will not be hindered by constant temperature conditions, and the accuracy of temperature measurement can be maintained at room temperature.
