Ways To Do A Lathe Operation With A Mill?

[Ryan Lee]

Ok; here is the deal. I had seen these before; but I had only imagined using the horizontal hole to do work. I hadn't wrapped my mind around using the vertical hole to do the same.

if you were to hold the pipe in a 3 jaw chuck or otherwise on the table

you could make your own boring head easily that can could punch the hole you need
take a disc smaller than the diameter but thick enough to house a toolbit
make a center point in the disc and drill/tap & use a suitable stub arbor (3/8,1/2,3/4???) to be held in a collet.
drill in perpendicular to the drive axis for a suitable toolbit and make provision for set screws to hold the tool bit.
the idea is best expressed as it's kinda like a flycutter really, but without the downward angle-
a flycutter may be even be able to be adapted for your needs, now that i think about it.
you may need to take test cuts and do a bunch of measuring , but it can be done!

I've done similar operations with a flycutter, though I didn't have as much material to remove as Ryan does. Tedious, but doable.

Ryan, do you have a rotary table?

Will I be able to make the cut I need using one of these?

I've bored out a pipe for a bushing with that exact tool. It will be slow with that much material to remove. You'll need to custom-grind the cutter, of course.

Better to get a boring head if you can afford it.

I don't have a rotary table. I was looking at this one: http://r.ebay.com/IpTtjM

What would be the ideal cutting tool to use with that?

I may go the boring head route. Are these the right cutters?

the ideal tool changes with every job, but in your case you'll want to use a relatively short, stiff , boring tool
maybe even something like this..

 

[Ryan Lee]

I'm looking for a set just like that in a 12mm size. Or even just the short one. Seems to all be 3/8" or 1/2".

Check out CDCOTOOLS.com they have a lot of boring heads and bars at reasonable prices Ryan.

This costs less than half as much and I got it in two days. It came with brazed bars and I made insert bars to fit it that used inserts I already had.

The boring head will work but a shorter bar might be better of your situation, generally you want to use the shortest, thickest bar that will do the job. I guess you could cut one of the supplied bars shorter...

Not sure about that rotary table, looks like it might be crappy... also, I wouldn't go for a tilting one, it will only be less accurate and rigid for the horizontal and vertical work that you'll need it for 99% of the time. There are other, better, ways to angle it should the need arise.

I may be missing something here, but why would you need a rotary table for this work?? If you can figure out how to mount the pipe on the rotary table, then you can just as easily mount it on the mill table. What am I missing? JR49
