5-Axis Milling
AXION LU-720
5-axis vertical machining center from the AXION LU series – generous working envelope with a compact footprint.
Our Axion LU-720 is the newest member of our 5-axis family. It closes the gap between the versatile LU-620 and the heavy-duty LU-800.
The high-performance 5-axis machining center Axion LU-720 impresses wherever workpieces need to be machined from multiple sides with high precision.
- Swivel-rotary table supported on both sides for high-precision cutting
- 60 / 120 / 220-position tool magazines as an option
- Fully enclosed work area
- Access via two doors for improved accessibility
- Low overall height, shallow depth
- Simultaneous 5-axis milling
- Perfect for automation with robots or pallet changers
Control systems: Heidenhain iTNC 640 and Siemens 840D.
