Thread: Looking for CNC lathe - prefer new, no CAM

Did you say what work envelope and material yet ? I should go back and look, but lazy.

Unless they sold it when fill in the blank was about to be needing replacement.

Smaller stuff, but I want to have some versatility for job shopping. Nothing exotic on materials.

My neighbor (Swiss shop) is selling a newer (2016) Mazak and barfeeder that they need to move to put in another Swiss machine. Look it up on Milwaukee Craigslist and see if it will do the job.

Here is a link.

With money, I love shopping. I'm still on to-lathe or not-to-lathe will the wife, but I think I'm going to get approved

Dude! Easier to get forgiveness than permission.

Do you have a spindle probe on your Brother? If not, going with a 2 axis lathe and putting a little of the savings toward a probe for your Brother could be a good way to go. You can nail second op work with the probe in process.
Basic live tooling on a lathe is pretty limiting. You have already heard of the TS Takisawa that Yamazen stocks. They have sub with full C and almost 5" of Y. That is the way shops are going for increased lathe versatility. With one turret still simple to program too. Price is right due to the volume installed.

That might be the way to go. That thought had crossed my mind. They have a TS in the Dallas showroom. I'm hoping to get up there soon to see it and the TCN. I'd love to see the TS demo even though I won't be getting that model anytime soon. Thanks

This is a "Smart" model. I am pretty sure they are a bottom of the line model mazak. Compare the specs.

I reckon the roller-linear ways they use now are so robust, and the guideway truck seals are so good, that it's OK to leave the rails exposed....?

Doosan has exposed rails for X axis on many roller guide lathes. I never heard of a problem in the time I worked for them. They still have way wipers and lube so I don't think the machine would suffer at all.

The only worry I can see is if a part actually drops onto the rail. How often does that occur?

Constant dousing with coolant I'd imagine would remove the grease from the rails. Fines getting into the wipers (although maybe less of those on a lathe). Parts dropping on rails. Those are the three reasons I don't like it.

I know Doosan is Korean, but where are the machines and their components built?

Doosan machines are built in South Korea.

For me, not that much. Even the few times it did happen it usually falls clear and slams the chip conveyor belt. Like I said, we never really had a problem. The lube is constantly metered, the wipers - if maintained - do their job.

On box way lathes - most of the time the ways are exposed as well. As long as you change the wipers - and I do regularly on mine - there's no problem. Just sayin'..

For very little (4%) more than that I got a quote with sub spindle. Doosan definitely came in as the most cost effective machine. With some of the best options

I was just worried about some things like the light weight of the machine and the fact that there were no way covers on what I thought were important surfaces. I was even able to see chips were getting into the blocks as the caps the used on the linear rails were slightly recessed and small fines can get stuck in there and dragged into the block. I see this being a problem over time.

If you never produce fine chips this will probably never be an issue.

Can anyone give me advice on collet tooling? I need something. I keep seeing ads for Royal. Their accu-length system seems pretty sweet, but pricey, about 4k then 2-300 per collet. Anyone use those? Thanks

We use their quick change collet system. Works just like advertised.

There are several offline packages that speak Mazatrol.

Definitely spend the extra money for an accu-length system no matter what the brand. I cheaped out way back and got a pullback style and the amount of parts scrapped from being too short would have paid for the accu-length many times over.
