Daewoo Puma 2500 vs Mori Seki NL2500SY Lathes

[frogier]

Can anyone help me? I am looking for some opinions on these lathes. My shop is looking into buying a new lathe with live tooling, y axis, and a sub spindle. We have a Mori nl2500y in our shop now. It’s working great for us. I don’t know to much about the Daewoo Puma 2500, We have also considered a Okuma. Any opinion would be appreciated

I recommend that get another Mori, it's will save you a lot of headace down the road. First you can share the tool accessories and once the program is work good one machine it have to good on other and less learning curve.......... Daewoo will save you about $6000 but it's doesn't help you in the long run.
Beside you like the Mori why bother to change.....

We have considered the tooling and that is swaying us towards the Mori. But the savings for the Daewoo is more like $60000.00. That is swaying us back to the Daewoo. Does anyone have an opinion on the Daewoo's reliability?

There is s reason the DEEWOOO is 60grand cheaper, Go for the Mori we have 15 Daewoo's here and I can think of nothing good to say about them. I have run Mori's for over 20 years and if it were my cash I would spend it on nothing but a MORI

A Daewoo is not so bad that everyone says, you get alot for the cheap price, but Mori is a bit sharper.If money was not the issue I would go for the mori. (we got both mori s and daewoo s at work)...

Are the Daewoo's reliable?

No not at all, For starters if you compare something as simple as the tool change system you will begin to see right there why the Mori is more exspensive.
A Mori is strictly mechanical once the signal is sent for tool chang it is completed cam drivin even the spindle unclamp. This makes for a much more reliable tool changer. The Daewoo has several switches that run off a cam and give signals for clamp and unclamp and so on. This cycle becomes weak after time and causes tool change faults. In 25 years I have never sean a Mori not complete a tool change. Other than some clown hitting an e-stop in mid cycle.
But our Makinos and Kitamuras and Deawoos all have ATC cycle problems they sometimes just do not complete. It happends trust me. BUY THE MORI

You paid for what you get.
I guess you are the only one know what is your company need, you can't buy a machine base on price, but that's all what your company need, ahhhh it's doesn't hurt. Beware, same thing as when you buy a car you can look at a Huyndai and compare to BMW. What inside of it is what you need(if it was me).
Ask your Deawoo dealer give you a software list detail, what is it include. I think they leave out a lot of features so the price be more reasonable. I'm not said you should get every option availuable they offer you, but it get quite expensive when you find out you will need it.

The best way to test out the machine is take a part you have in house and use the same program you run in house. Bring a good piece with you, then test cutting on their machine. Don't allow them to twist or change any RPM or feedrate(except M-code not all machine code are same), just cut exact the same way you make part in house, you will see the difference.

"TEST CUT TELL EVERYTHING".
"TEST CUT TELL EVERYTHING".
I still want the Mori over Deawoo.

Bluesman is correct. I have two Daewoo mills and they both stop in mid cycle
during toolchanges. I friend of mine also owns one and has the same problem.
Actually we both had the same problem today. All the machine dealers try do do is look it any direction other then there own.(Retention knob, toolholders, operator, air)
