CNC lathe

U-Turn 290 • 290 MC CNC

High precision square box-ways for rapid traverse speeds up to 30 m/min. They are precisely ground and have TURCITE-B antifriction coating.

Precision ballscrews of C3 accuracy grade.

– Cast iron bed has 30° inclination and recess for installation of chip removal conveyor.

– It ensures minimum vibrations under heavy-cutting conditions.

– High-speed servomotors used for driving live tools of the 12-pos. tooling turret allow for stable machining operations with no vibrations.

– Superior positioning accuracy and repeatability.
