Frequency of viewing probes under a microscope

[[An...]]

Hi,

We calibrate our probes weekly but I started to wonder if we should take a look at the probes under a microscope as well.

Is the anyone who does this and has that routine? Have you seen any benefits from it? Do you find wear that you normally don't catch during calibration?

I carry a 7x eye loop, I look at styli every day.

What do you think are the advantages of doing this? Do you find a lot of wear that would otherwise not be detected?

I'm trying to find reasons for my boss to buy a microscope 😁

Whenever I have results that are not as expected, I inspect the stylus that measured the feature with my eye loupe. This aids in detecting and correcting buildup and or debris on the stylus.

If the stylus is dirty or has buildup, clean it.

If the stylus is clean and free of buildup, inspect the feature for debris, etc, clean and remeasure.

9.96 out of ten times this clears an OOT condition quite quickly.

The main advantage is piece of mind and a good basis for reliable results.

I inspect our probes visually before every calibration (after cleaning) and like Richard everytime i got unexpected results.

Depending on the location of the defect or buildup and your calibration sequence you won`t detect all problems with a probe just through calibration.

 

The microscope is also important for the visual inspection of measurement objects before measurement in my opinion.

How can you otherwise put unexpected results into context?

Thank you..

That's exactly how my thoughts go too. It's fun to hear how you others do it and what your routines are.
