Daewoo opinions needed

[Elmer Fudd]

My boss is talking about getting a daewoo vmc. We allready have a mori but they cost too much. I like Haas but he says its not sturdy. We also have a Cincinati. 4 different kinds of machines. Thanks for your opinions, Dan

I don't have any experience with Daewoo mills

but their lathes are excellent.

If money wasn't an issue, I'd take a Daewoo over a Haas any day. You can probably buy 2 Haas's for what one Daewoo costs.

I am not familiar with Daewoo machines but this statement strikes me as absurd.

 

A HAAS is not sturdy but a lower end machine is?

 

To me this sounds like a simple case of Fadal Syndrome.

 

It just seems to me if you're buying a machine for "sturdiness" you don't buy a machine like a daewoo.

Dan,

 

I am with Gcode, I have never seen a Daewoo mill but we have puma lathe and it is excellent, Still going strong after 10 years

We have a Daewoo DVC-400 vertical pallet machine and are in the process of ordering another. 10,000 rpm, high feed rates ect. We mostly run alumn., but this thing has really helped out. We have a couple of fadals and some Excels, no Makinos yet. We've been running a 2 flute 1.25" inserted mill, 10,000 rpm, 300 ipm, .3dp, up to full slot width in 7050. works great.

Talked to one of the guys where I used to work, they have several newer Daewoo machines and like them a lot. They mostly run cast iron and alloy steel.

We have 3 Daewoos DMV 500 with a fanuc 18m controls. Have had very, very little problems with them. Seems to be a very good machine for the money.

Haas' definitely are not as rugged as a Mori or Matsuura or Okuma but they aren't exactly rattle boxes, either. If you are doing heavy steel and stainless machining, I don't think Haas would be option #1, but if you aren't hogging the machine to death I wouldn't be afraid of one. Daewoo has a pretty good reputation with lathes but I've never seen one of their milling machines, sounds like some of our members have had good experiences, though.

Yup, and I guess I should digress on my earlier comments.

I wouldn't concider a Daewoo a lower end machine.

As I said earlier, I've got no experience with

their mills, but a Daewoo lathe will kick a Haas

lathe up and down the block and never get out of breath. It's not even a fair fight.

We have 6 DMV400's & 2 DVC500's. The only major problems we have had with the DMV's are the spindle bearings & getting chips on the ways and wrecking the pillow bearings. Make sure you warm the spindle up first. The ceramic bearings aren't that tough. If you have one that goes bad, replace them with plain bearings and live with the lower speed. We had a DVC400 here for a couple of months and sent it back. It had chatter problems. Our newest DVC500 has a 930 CPU alarm that likes to pop up about twice a day. I think it has something to do with the yuasa indexer. For the most part I think they are great machines, just don't like the spindle bearings. We also have 17 daewoo lathes. I agree that they are a great machine. We run mostly cast iron.

I have to agree with gcode. I actually ran a daewoo lathe. used it mostly for production. oddly enough it was built like a mori kinda just had a different name. I think it was a mid 90's model though. Never ran a daewoo mill but I would think you could expect the same.

[cncchuck]

we have 2 daewoo mills and have had good results with them , we also have 3 daewoo puma 250 lathes which are a nice running machine .

Thanks for the input. Dan

We have a Daewoo DMV 4020 50 taper and use it to cut mild steel burnouts and steel castings mostly. It has been a very dependable machine although I wish we would have opted for the double arm tool changer. The Fanuc 21i controll has been flawless and Daewoos tech support is awesome. We got the mill complete with full 4th axis and of course chip conveyor for nearly exactly $100,000. If you have any specific questions fell free to email or call me anytime. HTH ~~~~~~~~~~Shady
