    DWX-50 not calibrating

    We have two Roland DWX50 machines. Our older one refuses to calibrate. We changed the motor/spindle last year and all worked fine. Lately, it will calibrate half way just fine, then suddenly, the thing will just stop calibrating and give me an error message saying "unexpected error, if there is...

    DWX-50 vs DWX-52dci

    We have two DWX50 milling machines and one DWX52dci. With the DWX50 machines, we use the Sum3d software. With the DWX52dci, we use Milbox. With Milbox, it takes nearly twice as long to mill a single zirconia unit. Any way to shorten the milling time in milbox? Nick

    DWX-50 Spindle Replacement

    Hey all, Wanted to know if anyone here has yet to replace their spindle in the DWX-50 Roland milling machine. I know the manual says the spindle has roughly 2000 hours of operating time before it should be replaced. Ours is at 1700 or so and we're preparing to buy a new spindle to have on...

    Well that sucked!!!

    This happened to us as well once. It was our first time running the "quick cycle" which is 6 hours instead of 12 hours. Tray broke, bead everywhere, but the crowns did not sinter properly though. We just never used to quick cycle again. Sticking with regular long cycle and it never happened again

    Milled Bridges Rocking Again

    Ah, okay. I've never used Titanium. Works well? It can be used the same as if it were a non-precious or SP alloy as far as applying porcelain goes?

    Milled Bridges Rocking Again

    No, I use no heat when doing this...only taking a bur and cutting away at it from the rear (away from bridge.)

    Milled Bridges Rocking Again

    Ive seen those options when choosing the material when entering cases. What exactly are those?

    Milled Bridges Rocking Again

    The waxers have been spruing a certain way....and on occasion I will mill and bridge with sprues/bar in order to keep them from incorrectly spruing it the way they have been. Yet it appears what Im doing is also wrong? So you're saying I shouldn't have a bar at all? Sounds odd to me since...

    Milled Bridges Rocking Again

    That photo shows what the machine mills out when I add the stabilizer bar. Its just one solid piece and not sprued with wax. And I cut back the bar to reduce that suck back effect. Today, after showing how to properly sprue and invest to these waxers yesterday, we had two big bridges that fit...

    Here are the photos from the spruing when I use the stabilizer bar.

    Milled Bridges Rocking Again

    Such as? I only know of wax alone. Ive heard of some using PMMA but not sure if that would work or not. Plus PMMA material is much more expensive than the wax material (so Ive been told). Nick

    Milled Bridges Rocking Again

    Well, today I sat my ass down and WATCHED the waxers sprue everything. Turns out they are heating up the bar in order to bend it, then spruing the bridges to it after it mildly cools. So, this is likely the main reason that the bridges are warping. Today, I made it known to them that they need...

    Milled Bridges Rocking Again

    What investment do you guys use for your milled wax? We use microstar HS. I doubt its the investment.....I think microstar is very good. Just wondering if there is another investment meant for any milled wax in particular.

    Milled Bridges Rocking Again

    That is what I personally suspect. The waxers, for the most part, dont speak much English (although they do understand it fairly well) and they take personal offense when you try to correct them. But yeah, I think Ill try to sprue it myself and see what happens. Typically, when investing, they...

    And we did try new wax pucks. Multiple ones actually. All rocked still.

    Milled Bridges Rocking Again

    We used proper amounts of metal. We also ensure that the waxups are not at the center of the ring for cooling purposes. We used to have investment breakdown with flash all over our metal units, but we fixed that by slowing down our run up times in the furnace.

    Milled Bridges Rocking Again

    We are using a Roland DWX-50 along with 3Shape scanning software and Sum3D milling software. By design parameters, are you speaking of our settings regarding cement gaps etc? When the wax is placed on the model, usually the wax bridge fits well. But once in metal, its terrible many times. Plus...

    Milled Bridges Rocking Again

    We solved the bridge issue we were having a while back, but its now happening again. Ive been using the stabilizer bar feature in Sum3D, and it seems to help somewhat, but these little bastards have begun to rock again. I suspect its the same issue as before (waxers carelessly spruing).....so I...

    How many of you mill all of your wax?

    Anyone still hand wax? We're about 50/50 right now....milling most major cases but hand waxing almost all of the single units. How did you guys like going from hand waxing to milling all the wax? Nick
