Description

Productivity benefits:

 -    High productivity.
 -    Optimised cycle times.
 -    Excellent visibility of the working area.
 -    Operational flexibility.
 -    Sustainable.
 -    Compact design.
 -    Optimised access.
 -    Technical support 24 hours a day, 7 days a week.


A unique machine concept:

·      Head in horizontal position:
Thanks to the horizontal arrangement of the head, a longer Z-axis travel is possible and swarf fall is optimised.

·      Maximum stability:
Thanks to the innovative design of the three axes, the distance between the guideways and the tool tip is minimised, giving the machine considerably higher stability.

·      Tunnel concept:
The tunnel concept makes it possible to machine the longest components, even when using extremely long tools, by swivelling and machining the workpiece within the working area without collisions.

·      Wide swivel range:
Three linear axes and two rotary axes allow 5-sided machining as well as simultaneous 5-axis interpolation, with a swivel range of 230 degrees on the A axis and 360 degrees on the B axis.
