How to correctly use and maintain precision measuring tools?

1. When inspecting parts on the machine tool, the inspection can only be carried out after the parts have stopped. Otherwise, the measuring surface of the measuring tool will not only wear out prematurely and lose accuracy, but also cause accidents.

 

2. Before testing, the measuring surface of the measuring tool and the surface of the tested measuring tool of the parts should be wiped clean, and no task dirt should be left, so as not to affect the detection accuracy due to the presence of dirt.

 

3. Do not stack the measuring tool with drills, tools, knives, etc. during use to avoid damage to the measuring tool. Don't just put the precision measuring tool on the machine tool, so as not to fall down and damage the measuring tool due to the vibration of the machine tool. Especially vernier calipers, etc., should be placed flat in a special box to avoid deformation of the ruler body.

 

4. Measuring tools are testing tools and cannot be used as substitutes for other tools. For example, using a vernier caliper to draw lines, a centimeter as a small hammer, a steel ruler as a screwdriver for screwing, and a steel ruler to clean up chips are all wrong.

 

5. Temperature has a great influence on the test results. The precise test of parts should make the parts and measuring tools be measured at 20℃. Generally, the test can be performed at room temperature. Otherwise, the measurement result will be inaccurate due to the thermal expansion and contraction characteristics of the metal material.

 

6. Do not place precision measuring tools near magnetic fields, such as on the magnetic table of a grinder, so as not to make the measuring tools magnetic.

 

7. When it is found that there are abnormal phenomena in the precision measurement, such as uneven surface of the measuring tool, burrs, rust spots, inaccurate scale, bending and deformation of the ruler body, inflexible movement, etc., the user should not disassemble and repair by himself, and it is not allowed to use a hammer by himself. Rough methods such as knocking, filing, and polishing with emery cloth may increase the error of the measuring tool. If the above situation is found, the user should take the initiative to send it to the metering station for maintenance, and continue to use it after checking the accuracy of the metering station.

 

8. After the measuring tools are used, they should be wiped clean in time. The precision measuring tools should be coated with a layer of anti-rust oil, placed in a special box, and stored in a dry place to avoid rust.

 

9. Regular verification and maintenance of precision measuring tools should be carried out. Precision measuring tools used for a long time should be sent to the measuring station for maintenance and verification accuracy on a regular basis, so as to avoid product quality accidents caused by excessive indication errors of the measuring tools.
