rainbow Mill-Zr 2nd is a compact device that uses computer-aided design and manufacturing (CAD / CAM) to mill artificial teeth from zirconium oxide blocks. Thanks to the transparent, cylindrical main body, progress can be easily monitored at any time and from different angles. The 260-degree opening facilitates the filling of the milling machine and also the removal of the finished product. Coloured illuminated rings around the central control element indicate the operating status.
