Lava™ Materials Approved CNC 250i Milling Machine

Lava™ Materials Approved CNC 250i Milling Machine

The newly developed CNC 250i is a Lava™ Materials approved compact 5 axes machine system for dry milling of both Lava™ frames and Lava™ Disc formats. With this, your dream of a 5 Axes compact unit is now a reality. The CNC 250i's sleek compact size allows it to conveniently fit into your small or mid size lab. Designed to be a desktop mill, each frame or disc is manually loaded for production of high quality Lava™ Restorations.

Milling Precision

The CNC 250i is a 5-axis desktop mill that easily handles your daily case load. Its cam module controls 3.5 axes and provides high quality Lava™ Restorations-no compromise on precision and fit for the Disc as well as frame formats. It can also be upgraded to wet milling capability at your convenience.

Designed for all Lava™ Frame and Disc materials

Built to be a compact and flexible desktop mill, the CNC 250i works with all the Lava™ materials. You simply load one Lava™ Frame or Lava™ Puck format at a time-Lava™ Zirconia, Lava™ Wax or the glass ceramic Lava™ DVS Digital Veneering System. You can do it all.

Small footprint saves space

Because it's designed for a workbench, it's easy to fit the CNC 250i in your lab. To save even more desktop space, the control laptop is movable for comfort.

Dust management

Specially designed to reduce dust and avoid contamination, the Lava™ Frame is enclosed during Milling. The system even connects to your own central dust abatement system or our qualified Lava™ CNC 240 Vacuum Unit.

Automated 10-time tool changer

Just add your choice of frame-Lava™ Zirconia, Lava™ Wax or Lava™ Digital Veneering System-and the machine will choose the right tool.
