How can I create milling data for the DWX-51D?

You can create milling data by using CAM software. For information on how to use the software and/or DWX-51D settings, please contact to your local dealer.  

Where is the DWX-51D made in?

The DWX-51D is made in Japan. The DWX-51D is registered as a general medical device.
Registration number: 22B3X10006000021

Why is a dust collector necessary?

It is to prevent not only the hazardous milling dust from getting out of the machine, but also to block milling dust from going inside the mechanical parts like the spindle unit, which may cause malfunctions of the device. Be sure to install the vacuum system which meets the required performance.

What are the specification requirements for a dust collector and a compressor?

Dust Collector:

  • Contamination of the compressed air by foreign material is undesirable. Use an oil-free compressor.
  • Moist air may cause rust. Use a device equipped with a dryer.
  • Stable pressure is required. Select a source that has an adequate tank capacity.
  • A hose (outer diameter: 6 mm (polyurethane tube)) is required.  
How many teeth can I mill out of one zirconia disc?

Approximately between 20 to 40 pieces.
* Available amount varies according to the shape of the restorations and/or CAM software settings.

What languages are usable in the VPanel?

Initialization is Not Performed or Initialization Fails

Is the front cover open?
Keep the front cover closed during startup. For safety, initialization is not performed when the cover is open at startup.

Is the milling bur caught on anything?
The milling bur attached to the spindle unit may fail to perform initialization if it is caught on the workpiece or rotary axis unit. Try to detach the milling bur using the emergency release function in VPanel.

Is anything caught on the spindle unit or rotary axis unit?
Open the maintenance cover, and make sure that no workpiece or milling waste is caught.

The Operation Button Does Not Respond

Is the front cover open?
This machine restricts some operations when the front cover is open. Close the cover.

Are you wearing gloves?
The operation button will not respond if you are wearing gloves. Operate the button with a bare hand.


VPanel Does Not Recognize the Machine

Is the cable connected?
Make sure that the cables are connected.
Refer to "Setup Guide" ("Connecting the Cables") to perform the work.

Is the driver installed correctly?
If the connection to the computer is not made in the procedure described, the driver may fail to install correctly. VPanel will not function normally if the driver is not configured correctly. Check again to ensure that the connection was made using the correct procedure.

Did you verify the connection procedure when connecting more than one machine?
There is a possibility that the connection procedure was performed incorrectly. Make sure that connections were performed correctly. Refer to "Setup Guide" ("Connecting Multiple Units") to perform the work.

Was the machine ID changed?
If the machine's ID has been changed, restart the machine.

Milling Quality Problems
The Milled Surface is Not Attractive

Is the workpiece firmly secured in place?
Check the mounting condition of the workpiece. Fasten the workpiece in place securely so that it will not slip out of place or come loose because of milling bur pressure or vibration during milling.

Is the milling bur worn?
If the same milling bur is used for milling for a long period of time, it will become worn and affect milling
results. Try replacing the milling bur with a new one. The work time of the milling bur can also be managed in VPanel.

Are the milling conditions too strict?
Strict milling conditions may affect milling results. Review the CAM milling conditions."

Where can I download the Windows driver, VPanel Updater and Firmware Installer?

 You can download them from our Support website.

How often should you change consumable parts?

Spindle Unit: 2,000 hours
Spindle Belt: 2,000 hours
* The replacement cycle is subject to usage conditions.

How should I prepare for milling?
  1. Tools: The tool(s) you set on the ATC magazine must be the same as the one(s) you configured in your CAM software.
  2. Material: The size/ thickness of the material you set on the machine must be the same as the one you configured in your CAM software.
  3. Stabilizing the Material:  The cap must be tightened firmly.
  4. Dust Collector:  The power must be turned on.
  5. Compressor:  Required amount of compressed air must be supplied.  
Is there anything I should do after the milling?

After a days work, clean the milling area using a brush or the dust collector. Also, clean the milling bur.
Clean off any milling waste around areas 1 to 3  in the following figure, as milling waste in these areas may affect the milling results. Use the Cleaning tool dialog box on the VPanel to clean the rotary axis unit.

How often should you change a tool?

Zirconia:  40 teeth
PMMA:  40 teeth
*This is a referential value when using one tool each for roughing and finishing. The replacement cycle varies according to usage conditions.

Can you change the position of the regulater?

Yes, you can set it on the left or right side of the unit, or two positions in the rear side.
