KXG Series

(Model Variant: KXG 45-14, KXG 45-23, KXG 60-23, KXG 90-23)

The KXG series enabling 5-axis, precision machining of large sized complex component in single setup from roughing to finishing operations. Machine is built with very high static and dynamic rigidity. Fixed walls in concrete specifically adapted to the harmonic requirements of the machine which maximises structure rigidity and allows maximum damping during demanding cutting conditions. 2-axis fork head with integrated torque motor and linear motor for linear axis enables high speed machining. Powerful high torque electro-spindle helps for high metal removal rate. The series finds wide range of application in Die-Mould machining, punches & tool machining and precision part machining for aeronautic, automotive, defense.
