Fanuc DDR 4th axis

[GOLETABRIAN]

Does anybody have any experience with these? If so what did you think?

Any info on ballpark cost?

Hi

It's a factory option only for the robodrill.
You get other companies that also make direct drive 4th axis, but they are a bit more than the gear driven ones and you require some options on the control for them.

If you're buying a new Robodrill and need 4th axis capability, I don't think you could make a better choice than the DDR rotary. As jrobson mentions though, only available factory equipped to my knowledge.

A friend of mine in San Ontonio is making custom high end camera parts on his Robodrill that he got with the DDR - it kicks ass! He has done some custom intake manifolds too that were cutting extremely fast - the index time of the DDR is the quickest I've seen yet - and it still has real good feed torque.

I was quoted it as a $14000 option for the robodrill

Mori makes a DDR aswell we have them on our mills and they are fast and we have had ours for about 1 1/2 years never any problems they run 2 shifts 5 days aweek

Ya, we're looking at the 4th/5th DDR from Mori. They have actually had the 4th axis one out for quite a long time now. We were quoted 80K installed for the Mori one. Hardinge makes one as well.
