Mori NT1000 vs NTX1000

[Herding Cats]

What's the difference? Say around 2010. Or is the NTX just a newer model of the NT?

Did a quick search and didn't see anything and I'm feeling kind lazy so figured I'd ask since I have a hunch @lobust knows.

The construction is very different. The NT series used a hexagonal ram for Y sliding in the X carriage, and the column moved only in Z, which was apparently a very rigid system, but according to the tech who installed our NTX was an absolutely miserable thing to work on when it needed adjustment or crash recovery.

The NTX copies the construction of the CTX series (DMG/Gildemeister) which is a fixed head and the whole column moves in YZ*. It's mechanically simpler with a lot less to go wrong.

So an NT1000 might be a viable machine for someone like myself who would do all repairs and maintenance? Rigidity and accuracy are always a priority to me over ease of maintenance and parts cost.

Highly doubtful I would be getting one any time soon but I have my eye on an auction just in case there is a lack of interest

Maybe. I am pretty comfortable with fixing up machines, mechanical/electrical/electronic, but there are a few things on these that I'd maybe not be so comfortable about owning without manufacturer support, for example most modernish b axis machines use roller cam with disk brake or curvic for B, whereas DMGM use an integrated torque motor with (I think, never been inside it to know for sure) a hydraulic expansion sleeve to clamp. All enclosed in a water jacket, and enveloping all the cabling and fluid lines etc. to the milling spindle. Pretty complex assembly with a lot of proprietary components... On the upside, there is not much mechanical to wear out compared to an integrex for example.

The turning spindles are all integrated motors, but that's true of most mill turns.

FWIW, the cheapest I have ever seen a b axis millturn go for was £34k, and it was a 20yo hard ridden integrex 400Y with KM spindle which is really undesirable in and of itself. Used NT1000's are still pretty much £100k machines, at least over here idk how it is stateside.

Bear in mind, the NT1000 is a very small work envelope compared to the bigger NT's or the NTX1000, so make sure it's big enough for what you want to do before you get excited and go on a drunken bidding spree...

I doubt I will be getting anything soon but I sometimes see stuff go cheap and always keep my eye out. I gave up drinking some time ago so I'm safe on the bidding front

Not to mention it's nice to learn about machines I don't have so in the event I ever come across a screaming deal that a decision needs to be made at a moments notice, I can make a semi informed one
