Environmental temperature and humidity control: Although the thermal expansion coefficient of granite is low, large fluctuations in temperature will still affect its dimensional accuracy. It is recommended to control the ambient temperature at 20 ° C ±1 ° C and maintain the relative humidity at 40%-60%RH. High humidity may cause the granite surface to absorb water vapor, long-term may cause surface erosion, damage the accuracy; Temperature changes can cause small expansions or contractions, interfering with the precise movement of a precision hydrostatic air float platform.
Avoid collision impact: Granite hardness is high but brittle, daily operation and equipment handling process, be careful to prevent tools, heavy objects and other impact on the base. Clear warning signs can be set up in the working area, and protective pads can be used during handling to reduce the risk of accidental impact, otherwise, once cracks or damage occur, the stability of the base and the accuracy of the platform will be seriously affected.
Regular cleaning and maintenance: In order to ensure the performance of the precision granite base, it is necessary to clean regularly. Daily use a soft dust-free cloth to wipe the surface dust; If there is any stain, clean it immediately with a neutral detergent and a wet cloth, and then dry it with a dry cloth. Do not use acid and alkali detergent to avoid corrosion of the surface. During regular deep cleaning, you can remove the relevant parts of the platform, carefully scrub with clean water and a soft brush to remove stubborn dirt, and then rinse and dry fully to prevent water stains from remaining.
Precision monitoring and calibration: Every 3-6 months, the use of professional measuring instruments to detect the flatness, straightness and other precision indicators of granite precision base. Once the accuracy deviation is found, contact professional maintenance personnel in time to calibrate and repair, to ensure that the precision static pressure air floating platform is always in the best operating state.
Taken together, the granite precision base performs well in terms of stability and conventional durability, while the mineral cast base has unique characteristics in terms of thermal expansion control and fatigue resistance. When enterprises and scientific research institutions choose the base of the precision static pressure air float platform, they need to make the most appropriate decision according to their own application scenarios, environmental conditions, budget and other factors.
