Oops! I looked inside the Fadal and the spindle drive says on it that
it is for rigid tapping. So I asked the guy I'm buying it from all
about rigid tapping and how it works and why he uses
compression/extension tap holders when he could have used ER collets
and he says the machine doesn't have rigid tapping. I had just assumed
it did because of the spindle drive. It turns out that it also needs
some chips installed to get the rigid tapping option. He never said it
had it, I just assumed and when we talked about it today he was
surprised that I didn't know the machine didn't have that option. So
now I will need to shop around for the chipset that will enable the
machine to rigid tap. Unless Iggy or someone just happens to have them
laying around. Thanks everyone for the rigid tapping info anyway. It's
one of the things that seems like a very worthwhile addition to the
machine.

Eric, just do tapping with a spring loaded tap holder. Especially if
you have a servo spindle that can maintain RPM.

That's how tapping is done on the machine now. The machine comes with
tapping holders and lots of the tap holders. Some are even the clutch
style. I will be looking for a good deal on the chips though because
rigid tapping can be much faster, apparently.

I believe on my Supermax with Fanuc control rigid tapping is slower.
It has to stop the spindle after it gets into tapping position to
start the rigid tap cycle. Then it restarts the spindle and taps ths
hole.

I'm not tring to set any productiuon records so I use the rigid tap
cycle, sometimes with rigid holders sometimes with ten/comp holders.

I think that it is not as big of a deal, myself. I implemented rigid
tapping on my Interact "because I could" and it was about $100 in
cost. Plus it makes some things easier, as I do not need to do
expensive computations of feedrates. Plus I can post videos on youtube.

Just being able to post videos on youtube has got to be a plus. Worth

Well, that was possible because you retrofitted the machine,
of course. Not sure if Eric is planning a retrofit. And, of course,
Mach does not do rigid tapping without a Galil card.

Yep, and I am very happy.

Greetings Iggy,
Why are you happy that you did not use Mach3? I have been considering
using Mach3 on a lathe conversion. I have seen a lathe running Mach3
threading parts and it seemed to work well.
Cheers,
Eric

IMHO, the call should be based on wheather you have steppers or
servos. Mach is a great stepper control but doesn't take position
feedback. EMC is slightly more complex to install and may be slightly
behind on ease of use, but it has ability to receive feedback from
encoders and drive servos directly.

Mach can be made to work with servos, and EMC can work with steppers.
So, if your heart is set on one control go for it.

Greetings Karl,
I have been using Gecko servo amps which close the loop themselves.
This means that the control software doesn't need to accept feedback
from the encoders. I haven't decided yet if this is a big
disadvantage. I think that in a low speed application it's just fine.
