CAUTION

Breathing difficulties caused by processing dust

Processing dust that gets into your lungs can cause breathing difficulties.

  • After dry machining, only clean the machine if the air extraction unit is properly installed and activated.
  • Wear a face mask of class FFP2 during the entire cleaning.
NOTICE

Damaging of the linear guides or the spindle when cleaning with compressed air

If you clean the working chamber with compressed air, material chips can reach the linear guides or the spindle bearings.

  • Never clean the working chamber with compressed air.

Do not pour additional water into the working chamber. The cooling liquid tank may overflow.

Cleaning the working chamber includes the following components:

  • Measuring key
  • Blank holder
  • View window
  • Webcam
  • Tool magazines
  • Tool magazine holder

These components have different maintenance intervals according to the maintenance table. Therefore, depending on the components that need to be cleaned, perform daily or weekly cleaning of the working chamber.

  • When performing the weekly cleaning, also perform the daily cleaning.

Performing the daily cleaning

  1. Have ready:
    • A wet cloth
    • A mild cleaning agent (optional)
    • A dry cloth (if the machine was used for dry machining only)
    • A suction unit
  2. Close the working chamber door.
  3. Move the axes into the cleaning position by selecting the depicted icon in the Machining view in DentalCNC.
  4. Open the working chamber door.
  5. Lift the protective strip (marked orange) at the left side and pull it out of the machine. Clean it thoroughly.
  6.  

  7. If the machine was used for dry machining only:
    1. Suck up the coarse dirt in the working chamber with the suction unit.
    2. Clean all surfaces and cracks in the working chamber thoroughly with the dry cloth. Use a mild cleaning agent if necessary.
  8. If the machine was used for wet machining: Thoroughly clean all surfaces and gaps in the working chamber with the damp cloth. Use a mild cleaning agent if necessary.
  9. Suction any machining residue off of the measuring sensor from a distance of 3 cm.
  10.  

  11. Clean all sides of the blank holder with a brush. Especially clean all openings and movable parts of the blank holder.
  12. Allow the working chamber to dry.
  13. Install the protective strip in the working chamber:
    1. Orient the protective strip so that the magnets (marked orange) are on the right bottom side.
    2. Correct orientation of the protective strip for installation

    3. Align the right and the bottom edge of the protective strip (colored green) with the imaginary orange lines which are depicted in the following illustration:
    4.  

    5. Push the protective strip to the right until it snaps in place.

    Correctly installed protective strip (marked orange)

    • The protective strip is immobilized by the magnets.
  14. Remove all machining residues above the slats on the right side (area marked orange):

    1. Use a suction unit for rough cleaning.

    2. Use a cloth for thorough cleaning.

     

     

  15. Wipe the nozzle plate of the spindle with a cloth.

     

  16. Close the working chamber door.
  17. Move the axes into the default position by selecting the depicted icon in the Machining view in DentalCNC.

  3. Clean the inside of the view window (marked orange) with a wet cloth. If necessary, use a mild cleaning agent.
  4. )

  5. Grab the working chamber door in the middle of the bottom edge and fold it downwards.

        NOTICE! Housing damage caused by incorrect aids and cleaning

      1. Clean the surface with a dry microfiber cloth.

        Be careful not to detach the symbol stickers. The adhesive foil is especially sensitive to friction and harsh cleaning agents.

      2. If some dirt cannot be removed this way, moisten the cloth. Use a pH neutral cleaning agent if necessary.

        • Avoid exposing the surface to alkaline or acidic substances. Metallic powder coating materials are especially sensitive.

        • If a special cleaning agent is used to remove certain impurities, check the suitability of the agent in advance at a hidden location on the painted part.
