CNC lathe

U-Turn 300 • 300 MC CNC

High-precision square box-ways allowing for rapid traverse speeds up to 30 m/min, they are precisely ground, resistant to increased loads and fitted with TURCITE-B anti-friction coating.

Precision ballscrews of C3 accuracy grade.


– Cast iron slant bed 30° ensuring minimum possible vibrations during heavy-duty machining.

– High-speed servomotors driving live tools in the 12-position turret allow for stable machining without vibrations (for U-Turn 300 MC CNC).

– High positioning accuracy & repeatability for superior machining results.
