That set up sounds sensible. It made me envision a simple arrangement
using a mounted angle grinder on a fixture with different pivot points.
Maybe CNC not needed at all.

In point form
- lay the rod in a long V (angle iron will be fine)
- rotate the rod at about 10RPM from the far end with a small reduction DC
motor and a 3-jaw chuck
- at the working end, support the rod with two large (80mm) overlapping
rollers (like used for balancing)
- have a third roller light

I think I have the only one. I made everything down to the motor
stator laminations.

Note: 'CNC Facing head' is also a good search.

To turn 1.25mm x 2m you would need to spend more effort on the support
than on the machining.
So, perhaps the best idea is to hold the work stationary and rotate
the cutter / grinder.
You would need a machine spindle with a CNC-controlled rotating ra
I thought I'd throw this out here because some of the ideas passed around
are really good. I thought someone might have a helpful suggestion.
I have an application where we need to grind a ball-end on the end of rod
that can be between 0.5 meters to 2 meters long and vary in diameter from
about 1
