In the field of ultra-precision motion control, the granite precision base of the air float ultra-precision motion module is the core support, and its performance is directly related to the operating accuracy of the module. Effective cleaning and maintenance is the key to maintain the excellent performance of granite precision base and extend the service life.
Daily cleaning: meticulous, protective precision
Surface dust cleaning: After the end of daily work, use a clean, soft dust-free cloth to gently wipe the granite precision base surface. This is because even if the dust particles in the air are small, the long-term accumulation may enter the gas film gap between the gas float slider and the base, destroy the uniformity of the gas film, and interfere with the ultra-precision movement of the module. When wiping, the action should be gentle and comprehensive, ensuring that every corner of the base is cleared of floating dust. For corners that are difficult to reach, the dust can be swept out with the help of a small brush without damaging the surface of the base.
Timely treatment of stains: Once there are stains on the surface of the base, such as cutting fluid sputtered during processing, lubricating oil stains, or handprints accidentally left by the operator, it must be treated immediately. For general stains, the neutral detergent can be sprayed on the dust-free cloth, gently wipe the stain, then wipe the residual detergent with a clean wet cloth, and finally dry with a dry dust-free cloth. Do not use detergent containing acidic or alkaline ingredients, so as not to corrode the granite surface, affecting its accuracy and beauty. If the stain is more stubborn, such as dry glue, special granite stain remover can be used, but before use, a small range of tests should be carried out in the inconspicuous place of the base to confirm that it will not cause damage to the base, and then carefully operated.
Regular deep cleaning: comprehensive maintenance, solid foundation
Deep cleaning cycle setting: According to the use environment and frequency, it is recommended to carry out a deep cleaning of the granite precision base every 1-2 months. If the module is in a high pollution, high humidity environment, or is used very frequently, the cleaning cycle should be appropriately shortened.
Cleaning process and key points: When deep cleaning, the other components on the ultra-precision motion module of the air float should be carefully removed first to avoid collision damage during the cleaning process. Then, use clean water with a soft brush to carefully scrub the surface of the granite base, focusing on cleaning the fine gaps and holes that are difficult to reach in daily cleaning, and removing the long-term accumulation of dirt. After brushing, rinse the base with plenty of water to ensure that all cleaning agents and dirt are thoroughly washed away. During the flushing process, a high-pressure water gun can be used (but the water pressure must be controlled to avoid impact on the base) to wash from different angles to improve the cleaning effect. After washing, place the base in a well-ventilated and dry environment to dry naturally, or use clean compressed air to dry, to prevent water spots or mildew caused by water stains on the surface of the base.
Maintenance measures: prevention, long-term care
Prevent collision damage: Although the hardness of granite is high, the brittleness is large, in the daily operation and maintenance process, special attention should be paid to prevent tools, workpieces and other heavy objects from colliding with the base. Clear warning signs can be set up in the work area to remind the operator to be careful. When moving devices or placing objects, handle them with care. If necessary, install protective pads around the bases to reduce the risk of collision.、
Humidity and temperature control: Keeping the temperature and humidity of the working environment stable is essential. Granite is more sensitive to humidity, and the high humidity environment is easy to adsorb water vapor on its surface, which may lead to surface erosion for a long time. The ideal relative humidity should be controlled between 40%-60%RH, which can be adjusted by installing dehumidifiers and humidifiers. In terms of temperature, drastic temperature changes will cause granite to expand and shrink, affecting its dimensional accuracy, it is recommended to control the ambient temperature at 20 ° C ±1 ° C, with the help of constant temperature and humidity air conditioning system to maintain a stable temperature and humidity environment.
Regular precision testing and calibration: every certain time (such as 3-6 months), professional measuring instruments are required to detect the flatness, straightness and other precision indicators of the granite precision base. If the accuracy deviation is found, professional maintenance personnel should be contacted in time for calibration and repair to ensure that the ultra-precision motion module of the air float is always in the best operating state.
Strictly follow the above cleaning and maintenance process, take full care of the granite precision base of the ultra-precision motion module of the air float, in order to give full play to its advantages of high precision and high stability, provide reliable guarantee for ultra-precision motion control, and help related industries to achieve higher precision manufacturing and scientific research breakthroughs.
