The compact 5-axis entry-level milling system
CORiTEC 250i and 250i CORiTEC dry machine systems are the most widely used CADICAM entry level systems. Thanks to their 5-axis technology, these machines can also produce complex dentures with diverging stumps without rework. Milling machines are ideal if a good price/performance ratio is the main principal objective + the very high flexibility of the machine system.
The 250i also features an option of wet processing. Wet processing takes place mostly in the processing of CAD/CAM blocks and special plastic materials.
Technical Highlights
- 5-axis machining system with up to 30° axis orientation
- Extraction system to extract the resulting particulate matter
- Tool runtime control/breakage control
- Automatic compressed air and coolant monitoring
- Integrated cooling circuit for cooling lubricant (only CORJTEC 250i)
- For processing of zirconium dioxide, PMMA, wax, plastics, and grindable block materials
- HF spindle up to 60,000 rpm
- Control software Remote DENTAL 2.0
- High-resolution and high-performance micro-step controllers and motors on all axes control PC with Windows 7/8
- Air purge system and cooling nozzles for wet processing are integrated in the spindle holder. High precision through integrated temperature compensation!
