CNC Taig lathe
- The reason I converted my mill to CNC was to make it easier to
convert my Taig lathe to CNC. The mill took about 6 months, the Taig
lathe took two days. I got most of it done last weekend. I still
have to add a speed sensor on the spindle. It is running on Mach 3
software with a HobbyCNC driver board. Here is another boring video
of the CNC taig cutting a convex shape and some rapid moves:
Higher resolution here:
Once I get the AMP round connectors I ordered, I will mount the
driver board to the rear of the divider. As it is I have to be very
careful to keep the chips off of it.

the 4 rods with two block of Al. There is no torsional rigidity just
using rods and the mount will flex around, it may not cause a problem in
a low power system, but it also has the advantage of protecting the
coupling and bearings from swarf/coolant, particularly if you fit some
thin sheet covers on the sides ;)
- Hello. Your conversion looks great! I always wondered if it would be
"OK" to do a CNC conversion to the Taig lathe just adding a screw to
the front. I guess the torque on the carriage isn't too bad?
I have been considering getting a little lathe, and I was thinking
about a Sherline considering the on-center drive is already there.
Is that normal threaded rod? ACME thread? Ballscrew? I'd be curious to
know where you got it too.
