Gold Line

A3 IRON STONE is a precision milling machine with all the main items to do milling on all materials, attachments assembly and surveying. Equipped with tri-dimensional movable arm with vertical stop and guide to realize holes, channels, chamfers and interlocks.
Furnished with electrical micro motor (with complete porta-chuck nuts ø 2,35 – 3 – 1,6 mm), digital electronic feeder with adjustable speed, electrical pedal, lockable model holder, spotlight and incorporated mandrel for attachments assembly and surveying.
A3 IRON STONE is also equipped with a set of accessories 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.

A3 IRON STONE can be also supplied with just a pre-arrangement to adopt each kind of laboratory turbine (upon dimensional compatibility check).

  • 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.
    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.

    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.

    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.

    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.

    Adjustable supporting crosspiece
    Support of the movable arm of the machine that allows adjusting the working position to the height of the model.

    Air turbine with feeder and pedal
    A turbine with water cooling, to avoid micro-fissures in the ceramic materials. Provided with a pneumatic pedal that allow a powerful control of the turbine via foot switch.


    TAP draining model holder
    Draining model holder provided with three protecting rings that avoid the water's fog spillage.



    MULTI-PIN draining plate
    Provided with special holes that grant a simple and effective water collection.
