    Performance features

    • Longitudinal and cross feeds are effected by ball leadscrews driven by servo motors. 
    • Either vertical 4-station or horizontal 6 and 8-station tool post as well as gang type tool post can be selected.The post is located on precision contrite gears with a high repeated positioning accuracy. 
    • Both chuck and tailstock are available with hydraulic or manual or pneumatic type. 
    • The spindle system is high in rigidity and accuracy. 
    • The surface of the bedways is supersonic frequency hardened and precision ground with a long service life.
