We use 2" x .049 wall tube cut 4" and deburred. We also use three
shorter lengths but in small quantities. I usually get 200' and send it
out. For the short lengths, we cut the tube on a bandsaw then deburr
each end, inner and outer, in a lathe.

Would it work if I slide 1' pieces onto a mandrel in the lathe and used
a pizza cutter type wheel in the cross slide to part the tube? Kind of
like a pipe cutter.
You want to cut long pieces of tubing into 1 foot ones, then cut those up
more on a lathe?

Do those pieces then get cut up again on some other machine?



bigger question - is it a big-assed lathe that you can feed the 2"
pipe through the spindle? Would definitely simplify things if it is.
In my last post I was ASSuming that was the case.

Hmm, it's a Reed Prentice and I think two inch WILL fit!

Easy then. Roller support on the long side. Feed tubing through lathe.
Make a stop that you can release to rotate 90 degrees and back to
alignment with an expanding rubber piece to hold the tubing in place. If
you wanted to make it more automated you could install a couple carbide
pieces that would de-burr the inner lip before the rubber section
expands. You would also want a stop that can be lifted up to stop the
tubing in line with the first operation.

Tubing feeds into lathe. Hits the first stop. Operator drops the stop
and uses a V shaped carbide to deburr both inside and outside edge.
Operator feeds the tube onto the end stop and locks it in place. Parting
tool on the tool holder cuts the tubing off. You can even have the tool
shaped so it deburrs the outside for the next step. Operator unlocks
the end stop and rotates it out and uses a simple hand tool or powered
handpiece to de-burr the inside. Remove finished part and repeat. Almost
like a screw machine.
