  • Adjustable supporting table

    Support of the working plane with high excursion that allows working also on high models.
    The picture shows the supporting table with the black removable locking plane AQ52 mounted on it.

    Removable locking plane AQ/52

    Black plane, shown in the first picture, that allows securing the model holder and, once removed, to work directly on the MULTI-PIN plane, suitable for wax milling and for ceramic materials finishing.


    Bur cooling circuit
    Pneumatic system that sends air or nebulized air-oil to the bur, during the wax and metal milling, allowing a quicker working, more polished walls and less consumption of burs.

    Integrated spotlight Adjustable lighting system of the machine that improves the tri-dimensional perspective of the model without shadows. Being not reflective it is less tiring.

    Base locking unit
    Very practical system, safe and reliable that allows to lock the base or to move it without friction on the whole working plane.


    Micro motor with quick bur release
    Motor assembly (with medium eccentricity 0.02 mm) that allows the release and the locking of the bur in a very short time (about 5 seconds), reducing the working time.

    Separate digital electronic feeder
    It supplies the electrical feeding to the machine and is equipped with all regulation and control devices. Easily removable and multi position for several uses.

    Mandrel for attachments assembly and surveying
    Accessory incorporated in the movable arm of the machine and coaxially positioned to the micro motor. This makes the attachments assembly and the surveying simultaneous and precise.

    Mechanical model holder AR1/M
    Very big model holder granting an excellent working stability.
    It allows to fix and lock many different kinds of models and to work without using any transfer technique.

    Stand-alone device for shadow-free illumination.

    A4 STONE set
    Set of accessories that can be assembled to the machine for the finishing of primary elements made of ceramic materials (sintered zirconia, zirconia implants, alumina, metal free all-ceramic).
    A turbine with water cooling, to avoid micro-fissures in the ceramic materials, and an innovative water collect system allow to work safely protecting all the elements of the machine.
