Maybe this didn't come thru as clear as it should have in the original post
either.

This thing appears to be generic.

From looking and all the extra connectors and inputs, it appears this company
had one base design that they installed different tools on and sold for
different tasks.
I'm sure board drills, pick & place, and inspection were other products offered.

The Z axis for example has no real need to move for a glue machine, a cheap
magnetic engage mechanism would be more than enough.

The linear bearings run on 1" rod.
It weight about 40 lbs.
It has hydraulic and pneumatic lines and controls integrated into the
mechanism.
I IS very overbuilt for a glue machine IMHO.


The only real milling I expect to do is on plastics, and maybe aluminum for
face plates, and the usual signs and such.

Maybe it won't be up to the loads of milling.

The REAL purpose is for one-off circuit board manufacture.
IE. Plotting lines, and drilling holes.

I'm sure it is up to the task mechanicaly, I can't detect any play in
the mechanism by hand. I'm sure digging out a good dial indicator, would find
some, but I can't feel any.

If it will do the boards, I'll be perfectly happy.

After all the circuit boards are the key to bigger and better controls
for bigger and better machines.
