DN Solutions SVM 4100

[Miller846]

Good Afternoon, Just curious if anyone has any experience with the new Doosan SVM 4100? What are the differences between the SVM and DNM, besides weight/rigidity? Looking for a machine to mainly cut aluminum parts fast and feel that the SVM might be a good fit but I also am looking for a quality machine that will last a long time with little to no issues. I know the SVM was built to directly compete with the VF2SS, just wondering if doosan cut corners in quality to do it. Thanks for your input!

I used to work for Doosan.
The SVM is every bit as high quality build as the DNM. It's mostly for aluminum/plastics.
It's a shade lighter and maybe not as robust but fully capable for its intended use. No corners were cut, per se, but it's specifically built for aluminum and plastics cutting. It's built with a 30/40 year lifespan in mind.

If you're going to cut a mix of metals with stainless and steels thrown in, go for the DNM. I've seen them chow on stainless, and tough steels all day and shrug it off.

I usually don't comment on these opinion type request posts since I work for DN Solutions. I am currently putting an SVM4100 and an SVM5100 through it's paces and I am impressed. We don't cut corners to compete with Haas, we don't have to. These machines are geared towards Aluminum cutting at high speed but I have also cut 42Rc mold steel on the SVM4100 and it didn't even flinch. The attached image was a test cut result in Aluminum. This was finished at 12K RPM and 150 IPM.

I have a SVM4100 and love it so far. It came down to this machine and a Brother and I went for 40 taper and more Z travel.
No expereince with the DNM series, so cant really offer anything there. The SVM did fit in a 8' high door and the DNM wouldnt.

Wow, a picture is definitely worth a thousand words. Very impressive finish! Is DN Solutions coming out with a SVM 5100 as well? Sounds like I will probably opt for the SVM over the DNM as I do 99% Aluminum/copper/plastics and could use the money saved on tooling. When I take a finish pass at 150 IPM on my haas, it definitely does not look like that, even with high end coolant, endmills, etc.

This.

Yes, we have an SVM5100L. The L version has a longer X axis travel at almost 50 inches. Same spindle and same tuning for high speed Aluminum cutting.

Any sense as to the saddle stiffness when the table is to one side? When my VF-5 is loaded there's a noticeable rock with the table extended, would like a better option for long parts.

Milland, Our Y Axis saddles are very wide, about 88" on the SVM5100L. There is only about 6" of overhang at the extreme limits of the X axis. There should be no sag. I cut an Aluminum part that was 24" long, did a waterline toolpath on a 5 degree tapered wall. After CMM, there was no more than .0005" error at any point on the form. This was cut at 138IPM. All other SVM models are similar proportions depending on the model. The tables are fully supported along the entire length of the X axis.

I thought the DNM was already in VF2SS territory?

Fast aluminum machining is Brother Speedio territory.

The DNM seems to be equivalent in price to an optioned up haas where as the SVM appears to have a few less options and comes in slightly cheaper than a similarly optioned haas. Both appear to be great machines from what I’ve seen.

What does a base SVM come with - Is a swarf conveyor / auger and TSC optional?

Its a machine I would be looking at to replace an ageing VMC we have but would want the above and control options to be able to handle some 3d machining.

This would go up against us getting another long bed robodrill for us but with this machine being a bit more flexible - it would be interesting to see how pricing stacks up.

Rick_H, here is what comes standard. Base price is 74K. Note it does come with AICCII and that also includes Nano Smoothing (G5.1 Q3). The avove photo I posted was with a stock machine.

That price is for the 4100 or 5100?
What does it cost to add work/tool probes and a conveyor?

 

[BROTHERFRANK]

If you are interested, Yamazen will run a test part for you and show you what the Speedio machines can do for you.

Correct. The DNM is a high line machine.

 

[rklopp]

How much less is the DEM 4000 machine, and what is taken away compared to the smaller SVM or DNM machines to get the price lower?

 

[DavidScott]

32mm ball screws are oversize???

 

[Milland]

32mm ball screws are oversize???

Well, the balls themselves are only 2mm, so it gives you a nice, strong core...

 

[Vancbiker]

32mm ball screws are oversize???

My thought too. Also bragging about 35mm linear ways?
