What’s this used for.

[Tim9]

Picked this up in an EBay tool lot. Not sure what it’s used for. I’m guessing it maybe came with a large machine tool like a tool cutter grinder. Maybe to set something since the round “handle “ has micrometer sort of gauging and when you turn it then the head moves out. The head is spring loaded. There are numerous tips which looks like would roach against grinder wheel profiles.

I can't quite see it from here.

Thanks Brino. Man I feel stupid. I fixed it. Sad thing is I first took the pic. Then posted the question. It’s just that I forgot to include said pic with the question.

here’s a closer look at one of them

Cutter grinder "Finger." used to index to the next tooth/flute. Various fingers for various uses. adjustment is to raise or lowere the tooth so it is ground perfectly.

 

[Tim9]

Ohh. I get it. So the tool tip touches the flute....or touches the cutter tooth so to speak.

 

[T Bredehoft]

With the wheel cutting down, the finger goes underneath the tooth, pointing up. when you're done grinding that tooth/flute, move sideways, off the wheel, rotate up, "click," rotate down to set against the tooth and repeat.

If you have it set up with the end mill in an air bearing holder you can run the holder in and out and cut the side of the end mill flute, the finger being stationary.

Thanks Brino.

No issues Tim.
It happens to me more than I'd like to admit.
I usually race to see if I can fix it before anyone notices........but I got you this time!

PS: Good thing Tom was here to reveal the purpose....I had NO clue!

 

[T Bredehoft]

I spent 500 hrs in my apprenticeship running a cutter grinder.

 

[Tim9]

Thanks To both of you. Brino for getting me in line.... And Tom for informing me its use. I’ve been accumulating and mind designing my cutter Grinder for a while now. I’ve assembled many of the parts already. Now I’m going to think about including this in it’s final design / build.
Very cool in my opinion

I spent 500 hrs in my apprenticeship running a cutter grinder.

And this is why I avoided the cutter grinding section in my last semester. I was already working in Fred's shop and saw what happened to the apprentice ahead of me.
