The maintenance content of the micrometer covers cleaning, lubrication and maintenance, storage and precautions for use.
Here is a clear summary of micrometer curing:
Ⅰ. Cleaning
1. Before using the micrometer, the dust and dirt on the work surface should be wiped off to avoid adsorption on the measuring surface and affect the accuracy.
2. Keep your hands clean to avoid contaminating the measuring surface of the micrometer.
3. After use, clean the micrometer in time to prevent dust, oil and other substances from adhering to the surface, which will affect the accuracy of subsequent measurements.
Ⅱ. Lubrication and maintenance
1. Lubrication: The digital display parts and sliding parts of the micrometer (such as the thimble and micrometer screw) should be filled with the appropriate amount of engine oil or light lubricating oil to maintain good lubrication and reduce wear and retardation.
2. Anti-rust treatment: The working surface of the micrometer that is not used for a short time can be coated with a thin layer of anti-rust oil and the coating should not be too thick to prevent affecting the measurement accuracy.
3. Avoid collision and vibration: During use, the collision and vibration of the micrometer should be reduced as much as possible to avoid damage to its accuracy and structure.
Ⅲ. Storage and safekeeping
1. Storage environment: The micrometer should be stored in a dry, ventilated place with little temperature change, and avoid humid, acidic, magnetic or high temperature and vibration environments.
2. Special containers: When the micrometer is not in use, it should be placed in a special utensil or box to avoid damage and fluctuations.
Ⅳ. Precautions for use
1. Correct Operation: Before use, the zero position should be adjusted according to the specifications of the micrometer to ensure the accuracy of the measurement results.
2. Visual inspection: Before measuring, the measuring surface of the micrometer and the measured part should be visually inspected to ensure that there are no visually visible defects, such as burrs, scratches, etc., and the measuring surface should be wiped clean.
Through meticulous maintenance work, it can be ensured that the micrometer always maintains good measurement accuracy and service life.
