Twin-spindle machining increases productivity by reducing part handling.
C-axis on twin spindles with unlimited rotational position-ing allows the machine to perform complex contour machining
The C3 precision ground ballscrews provide high accuracy and rapid feed rate. All axes are driven with AC servo motors. The high power thrust enables high accuracy cutting.
Heavy duty linear guideways supports high sta-bility, high precision and lower vibration during heavy duty machining.
The perpendicular motion of ±50mm to X-axis enables diverse and off-center machining for complicated parts.
Both spindles have C-axis control. C axis with hydraulic braking system provides spindle angle indexing and superior machining performance.
