This is a Boehringer 19x46 hydraulic tracer lathe.

I have a feeling that the tracer system can be disconnected and it can
be converted to a manual lathe. Is that true?

Not sure about that particular unit but yes every tracer lathe that I've ever run could also be operated as if it were an engine lathe and so unless the tracer is broken then there's no reason to remove it.

Tracers are very nice to have in that you can easily use a DNMG style insert tool and in a single chucking you can produce contours that include tapers, large radius fillets and so forth that would otherwise require use of cnc.

Biggest issue is safety; this class of machine was a mainstay shortly before cnc became prevalant and fully enclosed chip guarding came into normalcy--they are typically capable of very agressive metal removal rates when using carbide tooling which at high feedrates makes it difficult to accurately stop the carriage feed at the desired position etc when running without the tracer because the operator is already fairly well preoccupied ducking hot chips and trying to keep them from sticking to his forehead or falling down his shirt front if you catch my drift.

I have my doubts.

Do you have it home yet? If so -- look at what appears to be a
leadscrew, and see if it is threaded, or just a shaft with a keyway down
its length.

I don't see a quick-change gearbox on it.

It looks as though there is a cross-slide knob and a compound
knob, and a handwheel for the carriage, but I suspect that all require
hydraulic power to make the carriage move. (Well ... perhaps the
compound is manual. :-)

I don't even see anything which looks like gearshifts for the
spindle speed. (Unless those are knobs on what looks to me like a
hydraulic fluid tank.)

You might be able to get rough control by manipulating the
followers for the tracer mechanism -- but I would not bet on being able
to control it with any degree of accuracy that way.

Intersting that it has a 4-jaw chuck on the outboard end of the
spindle. A spider for stabilizing long workpieces? Or simply a storage
place for the chuck, and letting it act as a flywheel? :-)

Good Luck,
DoN.

I think that this lathe does not have any threading capabilities.

No, I could operate at least the X handle to make the carriage move
left and right, to look at the ways. The ways are covered and need the
carriage to move significantly to open up the relevant areas. By the
way, there was no significant wear where I looked.

I don't even see anything which looks like gearshifts for the

I think that it is a variable speed Reeves type mechanism. I will know
more soon.

It is definitely for long work pieces.

It reminds me of whats called an oil field lathe. But i suspect it is a
tube end finishing machine, note the two chucks on the spindle which
is common for working on long tubes, pipes and rods. I bet it has a
spindle bore of 3" or bigger. Worth big $$$$$ to the right buyer.

Just looking at the picture, it sure looks like it has all the normal
manual handles, so I would think so. You should be able to move
the toolpost by those handles when inspecting it. it may have
some apparatus like a telescopic taper attachment to sum in
the tracer movement to the crossfeed handle.

Indeed. The bigger spindle bores get more money.

By the way, sometimes material needs to be removed in successive

You just crank in the X axis screw the amount you want to take off for
each pass.
The chuck on the left looks like an air chuck. The tracer lathes are
sort of a obsolete item with the coming of CNC lathes. They still are
used in some applications but their sale value low. They are good for
repeat parts that have contours and tapers.

Yes. The question is, can it be used in manual mode.
