info fresatrici doosan

[rinato]

Hello everyone, as we are evaluating to retire a milling machine that gave all the spendable, now as now the most interesting piece is a doosan, vertical, 5assi (fixed bench/mountain mobile, head +/-115°, drowned table) 3000x800x700circa, 15000g/1', iso40, heidenain 530, plus some boundary nymnol.
should be an 850vm, if I don't remember badly.
from vs. workshops or with which you are in contact, the brand is worth the candle? their milling machines are appreciated or cajorable (small moulder ).
I know that they are Korean, but almost all European production is supplied by those parts. .
thank you for any help, reborn.

Hello reborn,

we have doosan puma turning machines and we are fully satisfied with them,
excellent price quality, precise and reliable.
I think the milling machines are on the same line.

Thanks for the match.
Greetings, reborn.

Good day to all
I am evaluating the purchase of a doosan milling machine vcf 850, I would like to know
if you already know her or have had the opportunity to work with us.
What do you think of precision and reliability?
compared with a tx goglio milling machine which would you choose?
thanks for your answers

Good day

Christian

hi, in the end we took it 'sta doosan vcf850(+/-).
the ham for a few months and fatality has dropped the job.. .
However, the mould worked on this is left to be mounted, so the millimeter means seem to hold them;-)
for the rest: consumes a lot of air (I also think to keep the rows in pressure) compared to the 2 big ones we already have (will be progress?), and sleigh oil (does not go to fat), which flows into the emulsible and there is the disolator with a ridiculous jar (you can not manage oiling, to throw less oil; on the old we can and/or we recover oil).
take into account that it does not have the charge of ut. during work, because the carousel is supportive to y, so you will not be able to deal with ut. twins etc.
in these days towers seems to have suffered a little the heat, because it is in shed with the ceiling to about 7 meters, rather than the most common 10) and to the ignition the oleodynamic power plant has done the bizze and we solved by forcing a couple of restarts with its internal switch), besides having aerated more.
I can't say that it's worse than the ten-year-old "base" by 1 meter, that you eat electronic cards as if they were *****ers (literally a piece every couple of years, to be generous). . .
The general impression is good, but I can only give you serious feedback in a couple of years, crossing my fingers.

a goglio comparable to me happened to see it "in installation" looking for us: it seemed beautiful robust in the parts in sight, a little light where normally you can not look, but one would suppose it is the counterpart of the "visible". but I can be wrong: I don't understand any size.

Good work, reborn.

Good work, reborn.

Hello reborn,
We also think of taking a vc850 to 3000mm, with the rotating table at 800mm, and the fanuc i.
Now after almost two years, are you happy with the car? it is not so much in the internet, so I have no idea, how it behaves for example during a heavy roughing, precision, reliability... ec.
thanks for your answers!

Hi, I have to admit that the car worked very little. at the time it seemed like there was some kind of work, then it didn't materialize. for ns. habits, the works carried out were however unexceptionable, but we had no opportunity to perform long heavy roughings, p.e.
I even think it's not the right machine, honestly. with the head equipped with 4 axis and an iso40 tells me the common sense that I have to sbancare light and fast. and so we did.

But a curious defect emerged: It's hard to clean it from the tricks behind the counter. the appropriate sprays of the emulsion (standard pump, I think 12bar) are not enough and you have to use a shaped iron to push down the shavings towards the conveyor (uncomfortable operation also for the operator from 1.9m ). or just doing very short tricks. It looks like little stuff, am is "fuck car"...
and the tool changes does not make them to the maximum z, but reached the point "y+" retracts to about half race of the z and then withdraw the head behind the carter etc. it is necessary to make us habit, especially for the stirrings that could be present in the area where "she" makes a retraction of the c.ut. or at least for us is a "new" regarding the other milling machines (elderly) we have.
at the level of software and cnc it does not help me anything to report, except that heidenain tnc530 was "customized" by/for doosan than that installed on the dmg and, e.g., certain logic of editing on the machine board are different. but nothing to which one cannot survive, indeed. I can think that you also understand with other cn and other builders.

As far as I'm concerned, we hope to change the wind, I'm sorry I can't be more helpful.
Greetings, reborn.

Hello reborn,

thanks for the quick answer. I'm sorry to hear that mancha is the right job for the grinder. Let's hope he recovers for the Future! I know the problem with the tool changer on our car, it's a similar situation, and it's very dangerous... What work do you do mainly, molds, welded construction work? What precision do you have?

greetings bernd

 

[rinato]

Hello, bernd.
we build molds for lav. cold sheet, and assimilar equipment (e.g. for the mobile tube ). therefore mainly plate, from the c45 up.
significant precision requirements we only have on a certain type of finished pieces (drawn) where they put "position within d0.1" for holes interaxes, the rest has broader tolerances and all however reachable. on the molds you work more "strict", but then there is almost always a little adjustment between the non-commercial components.
thank you, however, for the "worker" wish, I gladly oppose (you, on the other hand, in what field are you? )
Greetings, reborn.

 

[Bernd]

Hello reborn,

we do control blades, cubings and arches for the automotive. you can say everything for the production of plastic pieces after the molds. for example presses to glue pieces, atrezzi for assembly, the vernicatura ec. these works we make on a mill of cms, a 5-axis mill, but not suitable for working steel.
in our area are a couple of fingers that need steel pieces (welded construction and then worked).for these works, and also for the atrezzatures we look for a flexible working center with a dimension that can suit different jobs.
greetings, bernd

Hello reborn,

If I can disturb again, did you take the machine with optical lines?

Thank you, bernd

Hi, I have to check, but I think so (for mental fixation, especially )
