Hi, I'm Mike Corliss from Tormach. Today I'm going to show how to use
the boring head
to bore the ID of a hole.
The advantage of using a boring head
is you can bore any size hole you want basically. You can get different boring...
...bars. You can do real little holes.
The boring head is adjustable. You can do really big holes.
You can do oddball size holes. Stuff you can't drill to size,
stuff you can't buy a reamer for. It's real adjustable.
And you get a real round hole using a boring head.
When you first get your boring head,
you want to set up
you want to set...
...these side tension screws...
so they're snug,
but not overly tight, OK.
When you have them set right,
you can still move this dial,
That's how you adjust your boring...
...size.
You don't want to cinch these down tight.
The boring head won't move if you're using it correctly
The only time it will move if you are getting a lot of chatter.
And if you're getting a lot of chatter you are probably trying to go too fast anyways.
We'll put it in the spindle.
And then I've already pre-drilled a hole, that we are going to bore.
And I want to scratch on the side of the hole...
so I know where my boring bar is, so I have a starting point.
And to be able to see how,
when it scratches in,
take a black magic marker...
and blacken the hole.
Just in that one section, because I'll rock the boring head
through that one section until I scratch through that one section.
Now I'm going to the boring bar out until I scratch on the side
and scratch on the marker.
There, now we've scratched the side of the hole so we know, we've got a starting spot...
...for our boring head.
I've set my boring head, I've scratched off on the side of the hole,
now I'm going to dial my boring head out,
ten thou on the dial
then take a cut to see where I'm at.
I like to use a
little cutting fluid
if you are using coolant...
...that's fine too.
Just a little something to help.
Now I'm going to use the telescoping gauge to check the size of my hole.
Tip the telescoping gauge
so you're not straight up and down
tighten it,
and then rock it straight back towards you.
And then out of the hole.
Then once my telescoping gauge is set...
I cna mic a cross that to see where I'm at.
eight hundred forty-four thousands
but you really have to get it on the tip of the telescoping gauge which
Now I can adjust my boring head
Now add a little more
cutting oil to the hole.
And then just hit cycle start and take a finish cut.
Eight hundred and fifty-three thousands.
Here's the code I use
for the boring cycle.
A G85 is a boring cycle
feed down
and then feed back to the top
And that's how to use a
a boring head to bore the ID of a hole.
