TOP DYNAMICS THANKS TOINTEGRATED SPINDLE DRIVES

+ Liquid-cooled spindle drives and headstocks for optimum temperature stability

+ Integrated spindle drive with a speed of 4,000 rpm on main and counter spindle

+ Up to 48 kW and 680 Nm for optimum cutting performance

MAXIMUM STABILITY ANDLONG-TERM ACCURACY

+ Maximum stability through the use of large spindle bearings: ø 180 mm of front bearing

+ Glass scales in the X-axes of all tool holders for higher accuracy (also available as an option for the Z-axes)

+ Constant rigidity thanks to robust guides size 45 and ø 40 mm ball screws

INTEGRATED STEADY REST

+ Self-centering steady rest integrated in the turning unit

+ Incl. clamping range control and fine adjustment

+ High degree of rigidity

+ Retractable steady rest arms for maximum machining freedom

+ Patented concept

CELOS INTUITIVE USER INTERFACEFROM DMG MORI

+ Dialogue-based programming

+ App-based application

+ DMG MORI Ergoline® control with swivelling 21.5″ multi-touch screen
