In high-tech manufacturing fields such as semiconductors and optoelectronic displays, array detection equipment shoulders the significant responsibility of controlling product quality, with its precision even reaching the micrometer level. The granite base, as the core support of the equipment, plays a decisive role in the detection accuracy. Scientific maintenance of the granite base has become the key to ensuring the stable operation of the equipment.
The daily cleaning of the granite base is of vital importance. Residual dust, oil stains or detection reagents on the surface may all affect the probe or optical path. It is recommended to use a lint-free cloth dipped in deionized water to wipe the surface every day to remove particulate contaminants. For stubborn oil stains, neutral detergent should be used for treatment to avoid using strong acids or alkalis to corrode the granite. At the same time, every week, check the connection parts such as the glue injection and bolts, replace the aged joint sealing strips in time, and retighten the bolts with a torque wrench.
Environmental factors have a significant impact on granite machine bases. Although the thermal expansion coefficient of granite is relatively low, the temperature in the workshop still needs to be maintained at 23±1℃, with a fluctuation of no more than 0.5℃ per hour, and the relative humidity should be controlled at 45%-60%. In addition, vibration sources should not be placed around the machine base. Vibration isolation pads can be installed and the airflow should be controlled to prevent excessive wind speed from interfering with the measurement.
Professional maintenance is equally indispensable. Every year, a professional institution should be entrusted to calibrate the accuracy of the machine base, including the detection of indicators such as flatness, thermal stability, and vibration attenuation. After use in special scenarios, if it comes into contact with corrosive liquids, it is necessary to rinse it in time and take protective measures. After a long period of downtime, when restarting the equipment, it is necessary to run it idle for a period of time first to eliminate the accumulation of stress.
Through scientific maintenance methods, the service life of the granite base can be effectively prolonged, ensuring the high-precision operation of the array detection equipment. For high-tech manufacturing industries that pursue ultimate quality, attaching importance to the maintenance of granite machine bases is to safeguard product quality and enterprise competitiveness.
