      yeah, i missed the training day with CAP when they came to install, but they accidentally installed everything on an Admin active directory, so it's technically non operational until we get it reinstalled onto the proper Active Directory.

      I'll have to ask the CAM technician what his thoughts were, but it looks cool as hell

      We have Roland dxw 50 mill
      Any suggestions on buying replacement burs ?
      Seems we are not getting the full bur life out of current burs only about 50% of the suggested use
      Milling Argen Z disks -pmma and a little wax

      if you are getting short bur life then adjust your milling parameters because something is very wrong.

      I do not do the milling so I am a little naive
      What milling parameters would you suggest changing or what ur mill parameters are
      Thank you in advance for any and all help

      points to consider:

      1. not all makers of CAM are set up to have the same milling strategy, or use the same template to create toolpaths. not all are created equal. this means modifying the process of one may not mean the same to another.

      2. from your picture it would seem like the external finishing routine is doing one or more of the following: A: using too large of a tool, B: using too large of a step, C: skipping some steps, D: getting skipped due to glitching in the software, E: engaging too aggressively, F: miscalculating due to noise.

      3. desktop machines are highly subsceptible to wobble in their tabletops. if the table upon which the roland sits is flimsy or not sturdy, or is occupied by an identical mill, the table vibration will translate into the machine and make life miserable for your zirconia.

      4. diagnosing any of this is very hard to do with a single picture and no history. especially if you arent doing the milling yourself; why havent you worked with your mill operator to find out whats going on?

      We have sold many hundreds of Roland mills. Never taken one back due to customer dissatisfaction and Roland is the best when t comes to support. The DWX-50 was likely the mill that made milling in labs mainstream. The 50 did have a lot of plastic. The new DWX-51D is metal. In addition, they moved from wire drive system to the more conventional ball screws in the 51. The 50 had the rails exposed inside the mill chamber. The 51 has two compartments, the mill chamber and a second, in the back to keep the components clean. In addition, the suction for the mill keeps a negative air pressure inside the mill chamber. This makes for air moving into the mill from all cracks or seams in the door which reduces or eliminates dust from getting out of the mill during milling. Other improvements over the 50:
      1. Users can replace the spindle when needed. No need to ship your mill
      2. The spindle is inexpensive, under $2K. We have had several last 5k hours.
      3. A funnel-shaped mill chamber that enhances dust collection.
      4. The 51 comes with an ionizer to eliminate static when milling PMMA, resulting in a cleaner mill.
      5. New clamping system that will allow end milling for large Izir type cases.
      You will not go wrong with a Roland. it is priced affordably and designed to provide years of trouble free milling.
      I checked out the mills at CAP last week and found that our oldest mill has been running for over 12K hours, resulting in the production of 36,000 units. I did this as Sam and I did a webinar on the 51 & 52DC (disc changer). You can view it here.

      sorry to beat on cap again here, but i was having horrible results with the tools i was getting from them. far less than half the life they should have been getting.
      i have since tried a handful others and have stuck with TD and their burs for the time being. i am getting nearly 3x the life out of them and they are a rather large sum of capital less expensive. i have easily saved $1000 or more with that switch since last fall.
