info about work centers

[Kattivo83]

Good evening,
The company I work for is planning to purchase a new business center.
we talk about a vertical 3 axes for 90% machining on aluminum (prints).
the intent is to speed up the processing, managed mainly by cam.
Are we at a crossroads: doosan or dmg mori?
Can someone give me some advice?

Hello, what races are you evaluating?
what park do you have as reference?
What are you doing?
I fear that more than the machine itself, the strategies that make you available to the cam, and the speeds allowed by the tools are important.
Then the car and his cn have to do their duty, of course.
from what the various vendors tell me, if doosan is +/- Korean, dmg is not German "made in germany". .

in the house we have a wicker vmc1050 with selca control. the choice at the time was made by looking for a "hybrid" machine, which could be more or less universal (max 10,000 and turquoise). but, since we mainly work aluminum (5083 for thermoforming molds and 7075 for injection) we want to be faster in milling. for the races, currently we have 1000 x 600 x 600, and I would say that we are good, since the gap to have a y major is really so.I give reason on strategies and tools, but consider that aspect comes after, in the sense that at the moment we are braked both from the low number of turns (I believe that a 15.000 rpm is the minimum union for the alloys mentioned above) and for the structure in itself of the car: can not hold a constant f3000 in finish due to the control calibrations to avoid stratospheric drift errors. not to mention the rapids at 18 mt/min on x and y and 15 in z.
About the two brands, according to what I have read so far, doosan is the most commercial alternative to mazaks, who uses it tells me that it costs a little more than average but makes much more than average. dmg instead is the fusion of two of the most known brands of last twenty years: high quality at a price from capogiro. but this is what I read here and there, I wanted to gather opinions dictated by experience

Got it.
on aluminum are ignorant, x s and f, etc. we work steels, from c45 up.
we have a dmg with 1000x500 10000/1', of about ten years: honest for the price of then. Maybe a little tricky electronics, but we've always had trouble from the cabin.
a "very long" doosan has to get there, so serious reports, even if they are related to the steels, I will have in 2-3 years, hoping that everything always goes well...
we the great dmg we discarded for the combination of cheap racing, as well as for the definitely more challenging price.
and I have all the park frese on heidenain, almost for scaramanzia by now, as well as for practicality. Unfortunately if they make it pay.
in wild theory has been absorbed by heidenain, if it may interest you for some reason; but the languages are different, just.

Greetings, reborn.

Yes, I know the story of wild. what may be useful to know, is that fagor absorbed most wild programmers by making a new cn with almost the same interface. I thank you for the time you have devoted to this.

buy Italian you will not regret

hi shiren, to say the truth I gave a look at the site of the breton and it seems to me do only 5 axes, while the haas, which was the first option evaluated, we discarded it for assistance speeches.

 

[Il_Dada]

hi, given the type of work the choice to parer mio would be haas (machine that we are also evaluating us to increase the hours available even if we only work steel)
machines born as a concept for the processing of aluminium, but tested on hardened steels behave very well.
excellent price quality ratio in favor of table size and races much more generous than alternatives of equal band or higher.
very simple and intuitive control, two days and you let her go like a train.
excellent base and rigidity.
Another advantage is that aluminum tends to make the machine a little less longeva and with haas you can afford a total revision of the two-litre machine (just see how much skin tears you if you have to change a dmg or mikron spindle in my case and a haas...3000 euri and via new stick ).
As for the assistance speech I don't know how it's handled in the puglia, of course I can't but consider it in favor since it's 20 minutes from here....
good hunting, the sea of machine tools is infinite... .

dmg mori depends on the model, dmc v or nvx? are two completely different machines.
dmc v is a light center on roller guides, nvx is a real mori seiki on flat guides, probably wasted if you only make aluminum.
I believe that the doosan is now number one.
definitely lower as performance to Japanese but also prices are 30-40% lower.
treating the price you will see better figures of the haas but as doosan quality is much higher than haas.
on an electronic level I wouldn't pass the fact that doosan is based on fanuc (undisputed leader of cncs) while haas has his electronics. . .
at the level of reliability the haas electronics is not even comparable to fanuc.

thanks to all for the contribution. today the holder has signed the contract for the doosan. should deliver it within 20 days. I hope I can give you positive feedback.

What model?

 

[Kattivo83]

dnm650h

Can I ask why you ask?

 

[Kattivo83]

return to write in this discussion after a few months of work: the doosan is a bomb; not because it exploded. I don't add anything else.
