NX Series
NX nvu Series

(Model Variant: NX 2215 / 3215 / 3222 / 4222)

The Series developed on double column structure and greatly increased working envelop concept permitting machining large size heavy component and wider range of tool length to be accommodate in same setup. The series is available with greater load carrying capacity and option of horizontal head for 5-face machining. Z axis is hydraulically counter balanced to improve stability. Machining of complex workpiece such as injection moulds, forging dies, large plates, heavy engineering workpieces finds application with the series.
