Hello, all,
A friend locally has arranged to buy a Hardinge CHNC-I
for a manufacturing project.
I know a few people here have retrofitted these machines.
This one has a General Numerics control, but it seems to
have Parker servo amps and MTS brushless motors. I'm
guessing these may not be original. It still has the
Fanuc spindle drive.
He is in a garage shop environment, so likely we will
replace the spindle drive with a VFD capable of running
off single phase. The Parker amps are analog velocity
servos, and take single phase power.
Is the spindle ac or dc? I have a pm Fanuc ac spindle on
a project machine that I plan to try with a VFD. Toshiba
claims that their drive will drive most pm 3 phase motors.
We think it is AC, but my friend did NOT get pictures of the
motor data plate. The Fanuc spindle drive has 6 transistors
on the board, so that seems like a clue it must be AC.
Induction or PM, I have no idea.
Can anybody be good enough to send me their configs file
set? I know how to get the axes and spindle working, but
have never dealt with a tool turret.
I used John T's setup on mine. The only caveat is that it
does not verify the tool number after the turret settles,
mine will on rare occasions at first start skip to the
next tool and try and work with the wrong tool.
Hmm, that is not nice. Could cause an expensive crash.
This guy wants to make up to 30,000 aluminum housings on
it. I think he's NUTS, and am pretty sure he will
eventually go to China for either turned or cast parts. So,
I think he needs a reliable solution.
Might take just a little hack to the classic ladder to fix
it. Thanks, I'll check with John T! Or, is it online?
I looked around, but did not find it on the git repo.
We think the machine is set up for the 16C collet, and
has the air collet closer.
16C spindles have A2-5 noses, 5C have threaded as far as I
have seen.
Right, there's no thread on the nose, just an outside taper,
so it must be the A2-5.
Jon
