Longitudinal and cross feeds are effected by ball leadscrews. Driven by servo motors.
Either vertical or horizontal 4-station or 6-station tool post or gang tools can be selected. The post is located on precision contrite gears with a high repeated positioning accuracy.
Both chuck and tailstock are supplied with hydraulic or manual type.
The spindle system is high in the rigidity and accuracy.
