Aluminium profile measuring tool maintenance four methods to explain force

In the production of aluminum profiles, measuring tools are just like weapons in the inspection personnel. If the weapon is in a state of semi-paralysis or damage, the test results will not have any meaning, and there will be no supervisory control over product quality. Therefore, the maintenance and protection of measuring tools are very important. The following are the maintenance specifications for several measuring tools (applicable to commonly used testing tools):

1. The storage location of the measuring instrument should be kept clean and dry, free of vibration and non-corrosive gases, and away from places where the temperature changes widely or where there is a magnetic field. The gauges stored in the measuring case should be clean and dry, and no other debris should be stored.

2. After using the measuring tool, clean the surface stains, aluminum chips, and loosen the fastening device. When it is not used for a long time (more than one month), apply anti-rust oil on the measuring surface. When the measuring tool is not in use, it must be put into a protective case. It is best to use the full-time person as a dedicated person, and to make a record of the annual examination of the measuring tool by an authoritative organization.

3. Do not use grindstone or emery cloth to grind the surface of the gage and the measuring surface and the score line. Non-metering maintenance personnel are strictly prohibited from disassembling, refitting, and unauthorized repair of the gage.

4. When there is a burr on the surface of the workpiece, be sure to remove the burr, and then make measurements, otherwise it will wear the measuring tool, and will also affect the accuracy of the measurement results.

5. Do not touch the measuring surface of the measuring instrument with your hands, because sweat or other dirt on your hands can contaminate the measuring surface and cause it to rust. Do not mix the measuring tool with other tools and metal materials to avoid touching the measuring tool.

6. It is not allowed to use the tip of the claw of the caliper as a stylus, compass or other tool. It is not allowed to twist the two claws or use the measuring tool as a card.
