Professional China Precision Ceramic Straight Ruler - Precision Granite Cube – ZHONGHUI

We offer the high precision granite cubes with best protection package, sizes and precision grade are available according to your request.
The precision deviation for the granite cubes.

Because the entire production process of granite cubes from material selection, production to the final inspection must be performed in a constant temperature room ,after moving out of the constant temperature room, the fluctuation of external temperature and humidity will be relatively large,which would affect the accuracy of the granite cube. In addition, the excessive loading and unloading during transportation and the bumps on the road will also affect the granite cubes,the accuracy may also cause some deviations.

In order to ensure the precision of the granite cube, it is recommended to put it in the constant temperature room for 24 hours before using it for the first time.

Of course, we will also try our best to reduce the impact of transportation on the precision of granite products. When the granite cubes are shipped from our factory, they are packed in plywood cases, and in addition, they are protected by protective films and isolation plates. Under normal circumstances, the impact of the transportation process on the granite cubes will be very small, and there will only be a slight deviation in accuracy, which will basically not affect its use.

The granite precision cubes are now been widely used widely used in the measurement of flatness and perpendicular of equipment The precision granite cube can work in a widely range of environments because it has good acid and alkali resistance and high temperature resistance ability.
