What kind of mill do you own? and what's the lifespan?

[laceygoriDD]

I'm just wanting to get some information about some mills out there and how long they have lasted you!

roland dwx 51d
i think we are soon to be heading into year 3

What materials? How many units a month?

 

[laceygoriDD]

Lets call it a medium sized lab doing about 40 pucks a month of zirconia

 

[laceygoriDD]

Also, another question. How long do you think it takes a Roland to mill a pmma arch?

depends on the arch. we have done quite a few in the past few weeks. 2-5hr average....depends if its milling flanges or not. how many preps, etc.

assuming 20 units per puck times 40 pucks....you are no small lab!

counterpoint: imes650 that has broken down twice this year, is under 2 years old. pricetag nearly 6x as much as new roland51d

ouch!
im not an 800unit a month lab but we havent had so much as a hiccup from the roland!

My DWX50 is turning seven years old in March...never had a hiccup --- (knocks of wood )

The Roland dwx50 that we bought when we started the lab just died, 5 years, just about 50,000 units milled. 80 % zirc, 10% wax, 10% pmma.
Rebuild would cost about 4K at this point for the various things it needs, but we decided to put it to pasture, it had a good run.

We mill between 800-1000 units a month of zirconia on 2 Wieland minis. One is just over 3 years old and the other is under 2. The "newer" Wieland has broke down about 5 times in the past 2 years and we've had to send it in for repairs and get loaners in the meantime. The original mill has only failed once since we've had it. Just gave in and bought a Sirona MX5 3 weeks ago and its head and shoulders above the Wieland mills. Faster, quieter, cleaner and easier to maintain. Sirona's design software is awful but their mills and scanners are pretty good.

Nice! That's not too bad

Nice! Do you do any harder materials other than zirc?

Good to know! Sounds like a headache with that wieland.. with the sirona is it a closed system? do you have to use all their stuff with the mill?

Ohhh yeah forsure, time to total it lol. Did you buy another Roland or go with something else?

No, but you do have to pay extra to be able to import .stl files from 3Shape to mill. We have the Sirona design software but it's simply not in the same league as 3Shape.

Do you have to pay extra to sirona or do you have to buy an addition module from 3shape?

 

[WaxOnScanOff]

Extra fee paid to Sirona.

WaxOnScanOff do you have a network of Cerec dentist that can send you cases? I would look at the Versamill from Axsys Dental since Argen has 50+ of them milling zirconia. A work horse and not much more than buying a Roland. Axsys is a sponsor of DLN too
