Geometric Self Opening Die Heads
I've made simple die heads. Some driven by a tommy bar, others by a pin
in the mandrel that can be set up come out of the groove and free spin
when it reaches the stopping distance. recently I started researching
my $350 Lin Huan TL-25 lathe score in the long term plan to getting it
running again.
Its a copy of a Hardinge turret lathe. Jet, Enco, and probably some
others sold it under their own label with some form of "25" in the model
name. I've been watching videos during my connection time with the
brain sucker box while drinking coffee in the mornings. There are lots
of cool tool holders available for the turret, and I have some ideas for
the head stock top mounted parting blade holder to add "one more"
function to it for some repetitive jobs. There are parts I would
probably offer for sale more aggressively if I had this machine running
and a few setup configurations ready to go.
A lot of the "expensive" special tool holders for it are pretty easy to
make, and I may make them as needed or in some cases make batches.
I found only one really good video on setup for one of these machines.
Lots of guys did a short video that was basically "look at my machine,"
and a number of machinery dealers did a short video showing the machine
runs and most of the function work, but there was only one I found so
far that seemed to show the setup and setting up a job. Its about 3o
minutes long, and its a little slow for my taste, but the first 15
minutes shows his setup for a job, some of the limitations, and finally
cutting one piece in the job setup.
Here is where he introduces the part.
The video showed one tool that might very well be a challenge for me to
make. I also looked them up and new ones are fairly expensive. A self
opening die head. One some types of jobs this could really be an
efficiency tool. I am sure I can my shop made simple die heads on the
turret lathe much the same way I use them on the engine lathe, but I
have to stop, reverse, reengage the tool, thread the die off the part,
and then stop the lathe to switch it back to forward. The self opening
die head pops open when it reaches its "limit" which would allow me to
simple back off the turret and use the next tool. At most change the
speed (which is supposed to be shift on the fly). A speed change is
something I would have to do anyway if the next tool demands it.
If you don't want to watch the whole video here is where he runs through
one part.

I am sure if I look around I can find a used version of this tool for
less than a brand new one, but I need to ask. Have you used a tool like
this. The self opening die head, not a turret lathe. I am sure lots of
you have used a turret lathe. How easy was it to setup for each job?
How affordable where the thread jaws? Did you find it worked reliably?
Do you have nay other feedback for using one or reasons not to?
