I have an SL10 and a Doosan 220B. There is no comparison between the two. The Doosan runs the same program in 60% of the time the Haas does just due to the rapid times and tool changes. The Service on the Haas was Abysmal. The Doosan gets a checkup every year and keeps on running. It's a 2006 and the Haas is a 2004. I also bought a 2011 and a 2012 VM2 Haas. Between the two of them I've replaced SEVEN ballscrews, Three spindles. Both mills got out of the factorn with the Z Ballscrew bearing block not pinned to the chassis. I've sold every Haas except my little 2000 Mini and it just won't quit. Bought Maklino's and am MUCH happier. THE most important thing when buying machines is service. And Selway service is Legendary in it's piss poor quality. They put my Cuvic coupler back together with only TWO balls in it and then wanted to charge me to fix their screwup. Never again Then we can talk about their barfeeders,.,.,.Junk. Not accurate and slow. Pushrod bends. Won't feed...LNS is MUCH better

Great review, thanks! I own a basic 2 axis Haas St10 and quite recently bought a lynx 2100 lsyb. I agree with most of what you said, except: - Part catcher on the doosan. It is terrible for small light parts, misses a lot of them or parts stay stuck before reaching the conveyor. Also a big risk of crash having it fixed on the sub spindle if a part doesn't exit correctly and the sub starts moving. The Haas part catcher is dead simple. Not perfect at all but very reliable. - Thermal stability. Our doosan moves up to 0.003" during 60-90 minutes before getting stable. Might be an isolated issue with our machine though, the dealer is looking into it. Still, would go doosan again without hesitation, just for the noise...

Funny you mention the Parts Catcher on the Doosan ? They can be sort of fixed with a added on guard i guess you could call it. Thermal Stability dramas ? This goes for most machines that don't have Thermal Comp built into a machine. You would already know this by now. But a morning warm up before making parts normally settles down the worst machines. This is where the bonus of Lights Out Machining comes in very handy other than the obvious reasons. Because the temperature is more stable at night than day. All the best with your latest Doosan purchase. Definitely a Great machine to buy.

Seen the same machine also. All the things the LYNX 220/210 should be is already included in the LYNX 2600 It's as close to buying a Doosan Puma as you could go without spending the $$$$$. I definitely like the Big Bore Spindle which is fairly common on most CNC Lathes now but a huge plus if looking at buying a new Lathe. The heavier duty Live Tools is another plus. Never really liked the LYNX 220/210 that much, a great machine but the Live Tools are Not so good, Great for Drilling & Tapping some light duty Milling that's about it. The other plus i like with the Doosan range is you can option the machines with a Siemens Controller.

Had an early 2000s HAAS SL10. Was near a bay door. This was in Denver. In winter, if someone opened the bay door for more than a couple minutes, my next part was scrap. The machine also wouldn't run stainless, would just alarm out :( Had no "butt" to it at all. Drive belts snapped every few months. Part catcher never worked as far as I know. You can probably chalk most of this up to terrible maintenance, but from my experience, I'd rather spend an extra few bucks on a lathe than a HAAS. Not for a mill though.

I can whole heartedly agree and give credit to the Haas control for how intuitive it is, but most if not almost all Fanuc controls have rotary selector switches for rapids feeds speeds that are much more intuitive to use in my opinion When I am finishing a setup and walking thru the program, being able to twist the rapid selector becomes mindless as opposed to the rapid buttons on the Haas control. Subtle, and possibly nitpicky, but I feel others will agree on this that use a Fanuc control daily in their work.

I really wanted to buy a new Doosan a few months ago, but I went with a new Haas ST20Y. It was due to the Fanuc controls and having 20 x more button presses to do anything like touching off tools or loading a file from USB. Not very well thought out by Fanuc and then the graphics version running on top of the hmi is Windows. Lastly, the Doosan has twice the horsepower as the Haas (look at current/amperage ratings) but then uses a much smaller BMT45 turret vs Haas's BMT65. The machine looks really nice, much stiffer linear rails, nicer coolant tank, and rapids twice as fast, but the Fanuc controls killed it for me. I have several Haas machines so I'm used to them. The old Fadal requires spacebar to jump to different menus but still not as bad as the Fanuc.

We machine large 12” OD parts and our Haas machines don’t hold up as well as the Doosan does. We have 30 Haas machines and only 2 Doosan machines but convincing me to buy another Haas would be a touch sell I think unless you plan ahead to replace them every 5-6 years

Even if the individual sales rep is truly looking out to score a good sale and be price competitive (And I know many are really trying to be positive support for their clients) because of well, everything... it's hard to trust that as a customer until longer term basis of trust is there. And many to-be-customers do probably loose out on some great opportunities as a result which is a shame. I'm sure plenty of people are getting smoking deals below list for Haas stuff, even outside the ridiculous sales, but if I can at least look at the website and go "yeah that's the price they're listed at, and the sales guy is giving me a price a bit better than that" then at least I trust they aren't taking me for a ride. They might give other people better deals, that's great for them, I just like knowing that I can start somewhere and the sales guy knows I have that data. And especially for smaller shops and startups the ability to just see all the prices right there, so you know where a VF2 sits in comparison to the VF4 or the TM2 or the UMC500 or so-on. That can help say "we have been eyeing a TM2, but the VF2 is only a tiny bit more and has all these extra features" In fact that's what happened with our startup. Had we just been going by the sales guy who knew we were interested in the TM and had given quotes on that, we'd have been looking down the tunnel of TM stuff and been in a bit of a bubble. We might not have realized we would essentially paying for a loaded TM that could have just as easily been a base model VF that is a better machine in every way for us. A really keen Sales person might have seen that and made the suggestion, but part of me isn't sure. And certainly the website having pricing on it let us figure this out and change course at the last minute.

Some great points in the review. I own a HAAS SL-20 and a Mori NL2500SY as well as a Robodrill. Fanuc control is a pain to train on but so reliable, the Doosan is an exact copy of a Mori NL (one of the most popular lathes ever sold). I would never buy a live tool sub spindle lathe without full C axis on sub and I’m surprised haas would release one with only orientation. Orientation on my haas mill is pointless because it has a rubber coupling between spindle and motor so is not accurate (not sure how solid it is on Haas lathe sub) Love the Haas control. Hopefully Fanuc will sort the user friendly side of their control out as it really is a joke to a new user compared to Haas. (Cncmedcom pty Ltd)

Coming from the Haas lathe control and now having the Doosan ez guide mode(or whatever it's called), there was basically no learning curve. I would say they are both equally easy to use. Now the standard fanuc side, I still have no idea how to use it. The Puma does come standard with the auto tool setter arm. I wish the Lynx did as well for in process tool checks but I don't think it's even an option. As for holding size, the CL-1 held tenths regardless if it was hot or cold and the Lynx seems to move about .001" as it warms up but then it holds size all day once its up to temp. I'm assuming that's because it's a much larger casting and thermal expansion is more noticeable which I'm sure the larger haas lathe experience the same thing.

Either you got a good Haas Lathe, we got one that's not so good, or Haas has come a long ways with their new machines, when it comes to holding size. When running a long running job on our 2006 SL-10, I have seen between 0.003" and 0.007" change from start up to "operating temperature." And it usually takes between 4 and 6 hours of constant running before it finally settles down. If we stop it for lunch, we have to start over again, to a certain point, after lunch. Also, you mention the auto touch probe auto adjusts sizes while running at night, lights out? I am curious how that works. Not how the arm itself works, but making sure the part is the right size. We touch off tools on our manual probe, and that will get you within 0.005" of the correct size on the part. But it's never perfect. I guess if you are dealing with +/-0.015" for tolerances, that would be OK. We deal with parts having 0.0005" total tolerance on some features. Major difference there. An order of magnitude difference, just from where we touched off the tool! Certainly not saying the SL-10 we have is a bad machine. It is just much different than what you are talking about in these two categories.

If you wanted the ability to interpolate with the secondary spindle then why not buy a DS-30?
@PiersonWorkholding3 жыл бұрын
Never said we wanted it. The DS30 is a totally different machine.

Ds-30 does not have full c-axis on sub either.

HAAS parts catcher is a very bad design..have used it on sl20 alot.. the lid in the door jams all the time, or u often get long chips stuck in that tray. Alot of times small parts just bounce on that tray, and u can never find them again.. or just get stuck at the opening in the door

The Doosan should allow you to spec Siemens or Heidenhain controls and use Fanuc as a default ,so thats a Pro. Once you give the Siemens a try you won't go back , its super efficient and can be programmed in 3 different methods. Thermal stability: Ive seen upto 20um -30um from initial first component to say 10th depending on cutting loads. Im convinced its not only m/c warmup but rather the general temp rise within the enclosure,turret ,tool holder,coolant temp and bar to be machined tha have an effect.

Their are 3 methods to programming the fanuc as well. G code, conversational, macro. The cool thing with the fanuc is you can combine all three into a program and works perfectly.

Looking in from the outside of never using a haas, it seems like haas is running their company the same way the American car manufacturers do by focusing on selling a car with lots of features the public wants, instead of a truly well built car with decent features. You know, feeding on that "disposable" immediate gratification mentality.

After owning three Okuma machines. I would never buy a haas.

Just want to remind everyone that this is Haas vs Doosan, not Haas vs Okuma.

After my bad experience with a haas dealer trying to screw me with a new maching that was .0015” out and programming a customer machine that was +.003” out. I would never buy one are recommended any. I know theirs other very good machines out their.

Lol. Okuma is not even close in price to a Haas man. Doosan is much closer to price of an optioned up Haas and I think I may bet a Doosan as my next mill and maybe get rid of my haas.

Hass had to make it easy for the Russian defense manufacturing companies could run it
