Hello, I'm Mike Corliss with Tormach.
Today we're going to demo
the Haimer CENTRO Indicator.
Going to show you the indicator, a couple different tips you can get with it
and how to use it.
The box, instructions, the indicator body itself.
This is the arm
that keeps the indicator from rotating and here is the tip that comes with the indicator.
Okay, to assemble this guy take the nut off and then drop the tip in.
And then just snug that up.
The arbor for the Tormach machines.
You don't have to over tighten it. Just a good snug job is all it needs.
Here are a couple of the different tips.
The standard tip, I believe this is 5mm that comes with it.
This is an accessory tip. It has a 2mm ball for getting into smaller holes.
And then you have a bent tip
for doing larger holes.
The indicator itself can be used for holes or shafts.
There is a switch on the backside here. The way it is now is for holes when it is in B.
And then you turn it to W like such for doing a shaft.
The anti-rotation arm, the little flex arm, that goes in the hole on
the backside of the indicator body. Just presses in.
We'll just stick this arm up
in the hole in the casting.
And then to check it you can just swing the spindle by hand.
Just rotate it just to make sure everything is hitting
and the indicator body itself isn't spinning way out.
Jog the indicator down into the hole and then make sure
you have the tip preloaded a little bit. I'll jog it back up to show you.
The tip is on a pivot here.
So you can pivot it in or out for whatever size hole that you're doing.
You want to preload it on this red dial.
Without preload you would end up getting close and then you will run out of travel on the indicator.
The indicator won't be touching the side of the hole.
If you wait until you get into the hole you can't preload.
So you have to preload it just a little bit above.
Swivel it out then jog it back into the hole.
That should be good.
The directions say to run this either by hand
or approximately 80 RPM.
The Tormach does 100 so we'll use 100. It says max 150 RMP so 100 RPM should be great.
Close the door.
Spindle on at 100. M3 S100. Enter.
Okay, now you just switch axes
and keep dialing until your indicator travel...
First, you want the red one to go slower and then once you get the red one a little bit narrower on its movement
the black one will start moving a lot shallower.
You'll notice it go down.
I just try to watch one end of the needle travel. Right now I'm just watching the top end.
And as I am going the needle travel is not going as far.
Then switch axes.
Keep dialing until your indicator movement narrows.
So I'll keep going on one axis now until the indicator movement picks up
and then I'll switch back to the other axis.
Right about there.
The indicator face itself between each line segment is a hundredth of a millimeter. .01 millimeter.
So you're talking a very fine movement. Even with the indicator bouncing here a little bit
its still dialed in.
If you wanted to go real slow you can spin it by hand.
Check it on the X.
Check it on the Y. You can also check flatness with this.
I have to get is set right so it misses the tack holes.
So I don't have the part in there very flat.
That's how you would do it.
If you are checking your setup
you can check your flatness with the indicator tip also.
Anything else? You are going to use these for picking up holes,
picking up shafts and like I said you can use them for checking flatness too.
And the more you use these, they are really fast to use
once you get the hang of it.
You eyeball it pretty close to the center to either the center of your shaft or hole, you preload the indicator tip
and you get a feel for how fast you have to move it
to get that indicator in there.
It's a quick way to pick up your work pieces.
