Flat Probes?

[TomCat]

Hello everyone!

Still new to this hole CMM thing and trying to learn as much as i can on my own at my shop.. regardless of that fact. my boss wanted me to find out anything i can about a probe with a flat head that we could get to measure the inside of some small oil rings on some of our parts. i have looked into them online but im just not understanding the whole custom order section of websites and how i would want it constructed? if someone could post a link and just explain to me exactly what the specs i would be entering mean exactly that would be super awesome!!!

Thank you anyone who responds and i hope you all have a fantastic weekend!

Do you mean like a cylinder? I've never used one, but I've heard bad things about them.

Cylinder probes are quite useful, if you know how to use them in a correct manner.

Hmmm we have a couple, I'll do some research and give it a try next chance I get.

Disk probes are used for measuring grooves (snap ring, O-ring, etc.).
Here is a Youtube video on calibrating a disk probe.

If you have a little wiggle room, These can be quite useful for O-rings and grooves, with a small probe on the end

I used some flat tip like this, on a manual cmm, just measuring the distance of the end of a very small cylinder to a plane.

That' the only probe that I calibrate with 2 levels !

Another idea.. maybe using a star probe? Setups like the one below can be quite useful for ID features like grooves and chamfers. I use them all of the time.

I have to measure some ring grooves inside of one of our components.
I use this probe setup for them.Disk stylus.JPG
The 1mm tip I measure the Z locations of them and the disk for diameter and true position.
