The profilometer is a very fine measuring instrument. It measures the shape of plain lines of various mechanical parts. What preparations should be made for measuring an object? Let's take a look.

1. Preparations before starting

In the current instrument market, many precision instruments have high requirements for the environment. The temperature must be controlled between 20 ° C ± 2 ° C, usually between 18 ° C and - 24 ° C, and the humidity should be controlled between 45% and 75%. The guide rail on the measuring instrument has a high accuracy. If there is dust or foreign matter, the guide rail will be scratched. In addition to dust and impurities, you can also use aviation gasoline to wipe the metal guide rail and anhydrous ethanol to wipe the granite guide rail. Sometimes it is easy to misunderstand that the image measuring instrument is the same as other machines, and the guide rail needs to be lubricated during maintenance.

In fact, this is incorrect. Usually, only a small amount of anti rust oil can be applied to drive components, such as screws and magnetic strips. Preparation temperature Before starting the machine, please check its humidity and instrument cleanliness, then check whether the power supply works normally, and regularly check the grounding of the regulated power supply.

2. How to prepare the measurement process

Clean the workpiece to be tested before putting it on the test bench to prevent the mechanical residues on the workpiece from damaging the accuracy and life. Large workpieces should be handled carefully to avoid damaging the instrument. The small workpiece must be fixed and then measured, otherwise the accuracy result will be affected. Be careful when rotating the lens during measurement, and do not hit the measured workpiece.

3. After measurement

After the measurement, the maintenance has not been completed. Make sure to clean the working surface and keep the workbench clean. Please also check the slides and do not leave any debris or water stains on the slides. When finished, turn off the power and turn off the power.
