Micrometer is a precision measurement tool, and damage to its measuring surfaces can directly affect measurement
accuracy. How should we repair the measuring surfaces of a micrometer after damage? Today, let's delve into the
repair methods and precautions for the measuring surfaces of a micrometer in detail.
Ⅰ、Assess the extent of damage
1. Minor wear: If the measuring surfaces only have minor wear, such as fine scratches,
they can be polished and repaired using abrasive paste.
2. Severe wear or deformation: If the measuring surfaces exhibit severe wear, deformation, or defects,
they require repair or replacement of the anvil by professionals.
3. Rust: If rust appears on the measuring surfaces, it needs to be removed first before proceeding
with polishing or replacement.
Ⅱ、Repair methods
1. Polishing with abrasive paste: For measuring surfaces with minor wear, diamond abrasive paste can be used
for polishing. When polishing, it is important to apply even pressure to avoid causing new damage. After polishing,
wipe the surface clean with a clean cloth.
2. Professional repair: For measuring surfaces with severe wear or deformation, it is recommended to send them
to a professional metrology institution or manufacturer for repair. They possess specialized equipment
and technology to ensure the quality of the repair.
3. Replacing the anvil: If the measuring surfaces are severely damaged and cannot be repaired, a new anvil needs
to be installed. After replacing the anvil, recalibration is required.
Ⅲ、Precautions
1. During the repair process, be cautious and careful to avoid causing secondary damage to the micrometer.
2. After the repair, recalibration is necessary to ensure measurement accuracy.
3. Non-professionals are not recommended to perform complex repair operations by themselves
to avoid damaging the micrometer.
4. Regular maintenance and care of the micrometer can effectively extend its service life and reduce damage
to the measuring surfaces.
5. When using the micrometer, handle it with care, avoiding collisions and drops.
6. After measurement, clean the micrometer promptly and store it in a dry and clean environment.
Ⅳ、Preventive Measures
1. Proper use of the micrometer: When using the micrometer, follow the correct operating procedures to avoid
applying excessive force or measuring workpieces beyond its measuring range.
2. Regular maintenance: Regularly clean and lubricate the micrometer to effectively prevent wear
and rust on the measuring surfaces.
3. Proper storage: Storing the micrometer in a dry and clean environment can prevent it from becoming
damp and corroded.
