Doosan T 3600D - Anyone have experience with this machine?

Hello! New to forum. We are looking at a Doosan T 3600D. Pretty cool little machine. We currently have a couple Fanuc Robodrills and love them.

What's nice about the Doosan is price, and the rotary pallet changer. Does anyone have any experience with this machine? (all we do is aluminum, and fairly light machining of small parts (same parts over and over))

Curious about the long term reliability / maintenance requirements compared to a Robodrill or Speedio.

The rotary pallet changer is very appealing as it allows full utilization of the spindle. Spindle should be on nearly all day.

Later next year we plan to add a robot to load/unload. (either on a new robodrill or speedio or to this Doosan). Again the rotary table is very appealing for manual or robot loading/unloading as it allows the spindle to keep working during change overs.

Any feedback, reviews, or insights into the Doosan would be greatly appreciated.
 
The Brother Quick Table pallet system like on the R450 and R650 has basically been around for 25 years with over 20,000 successful installs. You should get started on that road if you can. The Brother pallet does not lift, no chance for chips and coolant fouling it up, first tool change can be done simultaneously with pallet change and super clean to add rotaries, 4ths and/or 5ths. The cabling goes down through the center of the table and the table does a 180 back and forth so no chance of cables getting tweaked...
 
Thanks Brotherfrank! I've been looking at the brother with rotary table as well. From my understanding, the Doosan operates the same way. I'll find out more this week.

Something to consider....

Doosan builds a wide variety of machines from this small one to quite large machines. Brother specializes in small machines. I suspect that a specialist builder will make a better performing machine than a machine from a generalist builder.
 
I ran one at IMTS 2012. A great machine (granted my bias), and really overbuilt for what you want to cut. I demo'd it using 4340 steel. Excellent parts and support. Built for the long run. Capable of taking a good cut in steel as well.
 
Wanted to revive this and see if anybody has experience with the Doosan T3600D. Last December we looked at it, but we opted for another robodrill instead.

We are looking at adding another machine again, and the Doosan is still intriguing because of the price point, and rotary table. My concerns are, there doesn't seem to be a lot of them out there. (at least I can't seem to find anyone with one, or get feedback on them.)

Any insights, or thoughts on this machine would be greatly appreciated!

(It would be used to run one of our core products. Cycle time is short, so the load/unload time would match machining time.)

Thanks!
 
Do you have a Brother distributor there? The R450 and R650 are superb. Have them run your program for you. The Brother will run your parts faster (if they are currently done on Robodrills), the pallet system is rock solid and reliable. The machines will be a much better value in the long run.
 
Thanks BrotherFrank - We do have a distributor close by!

Check out this new R650X2 we just set up for a client:

41 Tool ATC, twin spindle tilting rotaries on both pallets, 1000 psi coolant thru, 10k rpm BBT High Torque spindle tapping 3/4 NPT like butter. Also available with a 16k rpm BBT spindle.

I've said it before, but it's hard to appreciate the speed of what's really going on in those videos sometimes. I know that capturing this in the real world is not really easy/practical. But if you ever replace a machine with a Brother that's the same part, fixture, etc, please do try to get a 'before' video of the old Haas machine being replaced (or whatever it is) and an 'after' video on the Brother machine. That really would help put in perspective how quick they are.

Nice to see a larger tool magazine on these machines.

Also, I'm disappointed - I'm sure that 2outof3 is too - that there's more than one part on that pallet... Everyone knows 1 at a time is best. ;)
 
I like two parts for certain situations. Cuts the non-cutting time in half. Even though the Brother has very low non-cutting time it still adds up (250,000 parts per year). Cycle time was 80 seconds/part doing two at a time with 19 tool changes and load/unload. Without the twin rotary and pallet changer, more like 120 seconds. Also the family of parts required the 41 Tool magazine to handle all the variations with minor change over.

By putting that video up I was trying to share with the OP and anyone else interested how cleanly you can add rotaries to a Brother pallet change VMC.

What is the tool change time with the 41 tool magazine vs. the standard Speedio?
 
Now THAT sounds just like a tool salesman......:fight:

Moreso just picking on their preference a little & having a little fun. I certainly "get it" why you would run multiple parts per pallet.

And for the record - I *USED* to be a tool salesman. If I were *STILL* a tool salesman, I'd have told them they need to run the tools faster... :D
 
Why would that be a machine tool salesman thing?

Because tool salesmen are often clueless when it comes to machine optimization........
All they care about is filling their pockets.

Now tooling engineers, they know what they are doing. :fight:

Also, just poking at Jashley a bit.

But of course most high production auto parts are single part ups. While some and I would admit most salespeople are clueless, BROTHERFRANK is an expert at making parts on Brothers and after 32 years of this shenanigans', I can hold my own. ;)

You actually mis-quoted me. I DIDN'T say "machine tool salesman" I said "tool salesman". :D
I wasn't directing it seriously at anyone. And I'll agree, you two guys and Jashley are all VERY good at what you do.

Let's say "Tool and Machine Tool Engineers".......
