Looking for a CNC lathe - Open my eyes beyond Mazak

Looking for a CNC Lathe for small parts. mostly 2 axis work, but I'm open to more axis as I can definitely use more options. Machining stainless small diameter .0004" total tolerance.

Must have a bar feeder and must have a parts catcher... I.e. run lights out.

I know mazak so thats my go to, but my ideal machine isn't showing up on the used market.

Power isn't an issue.

What are your go to oems in this area that might possibly open up my potential of finding a good machine used in the $20-50K range?

You have Hyundai at the top of the list, an Okuma at the bottom. So what is this a ratio of?

We have 2 leadwell lathes, one live tool, one not. Both have an pneumatic parts catcher but the delay time the machine waits on the parts catcher is long, but that may be because there a little older, about 2003-2008. I believe you can equip a bar feed to them. They have taken a couple hard crashes and other than aligning the turret, they have been sturdy and powerful.


Edit: I will add that the biggest issue we had was the draw tube actuator had leaked coolant down the drain line for the hydraulic system, fogging and contaminating the fluid. We only see the issue when really blasting coolant down the draw tube. It is the stock seals that may be needing replaced. They also have tool setters

I've seen this before.
I think that you could make up a "slinger" to bolt to, or press in, or somehow position on the back of the spindle to not allow it to creep back towards the actuator.

If you're really looking for 0.0004" total tolerance, I'd say your best bet would be a Hardinge Super Precision as it will probaly be the most stable throughout the day vs. anything else out there. There should be tons in your neck of the woods, and service guys to match.

I don't think that. ANY CNC Lathe should hold .0004" all day. At least any decent one.
