Fraud Blocker

6 ways to destroy your Rockwell hardness tester

We wrote this article to dispel a myth: that the hardness testers are so solid to be unbreakable.

The hardness testers are very delicate even if they do not seem so.

Often, unintentionally we commit mistakes that may damage the instrument.

It must has happened to anyone at least once to block the indenter or trigger a state of emergency. It is normal and it happens to everyone.

But why waiting to make a false move to realize which mistakes entail a problem?

That’s why we have decided to summarize 6 actions to absolutely avoid.

Let’s analyse them.

1

Not respecting the orthogonality and the flatness of the sample. Those two conditions are vital to be respected regardless to the dimension and the geometry: if one of those should fail, some unpleasant consequences might arise.

Let’s have a look here, we wanted to bring to the extreme this concept, putting our Rockwell hardness tester to the test.

2

Use a hummer to unblock the spindle

3

Lubricate abundantly the Rockwell hardness tester

4

Use the pliers to remove the indenter

5

Use just one test sample to make the calibration and see that there is a label in contact with the anvil on it. Keep in mind that the international standards suggest to use more than one test sample in order to make a hardness comparison. Moreover, check that the label isn’t in contact with the anvil. We have explained why this is so important here

6

Move the sample test during the Rockwell hardness test cycle.
This is the most common way to block the hardness tester and irrevocably damage it.

If you avoid these actions, both you and your Rockwell hardness tester will always work in safety.

With any doubt, there are some production environments that can stress the instrument more than necessary. Unfortunately, when these conditions occur, there are no additional tips or advice to follow. Everything depends on your hardness tester performance.

If you have an instrument that takes into account those uncertainty is really helpful, for sure. 

That’s why we have designed our AXE440 Rockwell hardness tester.

Our R&D department has projected it to ensure the maximum comfort of use, even in extreme conditions!
