MHN Series

Bridge-type Milling Machine MHN Series
    • With Vision Wide tradition in making high rigidity machine structures, the MHN series not only plays a high precision indicator in 5-face machining centers but also provides a full range of high efficiency cutting performance through its rigidity structure design and excellent geometric accuracy.
    • More than 1,1m height of rigidity stepped beam structure efficiency enhances guideway span and provides Y-axis straightness and rigidity needed for heavy cutting.
    • Y-axis with a 65mm ultra-load guideway not only enhances more than 40% rigidity on higher cutting load but also extends the longer lifetime.
    • Full stroke supported design, thick and extra-wide design size of bed structure with highly rigid structure, increases table load capacity and workpiece movement dynamic level, reaches the cutting stability and enhances anti-vibration.
    • One-piece casting column structure with thick column section size, effectively links the rigidity of beam and base, enhancing YZ-axis machining rigidity.
    • XY-axis precision supporter mechanism prevents ball screw sag, enhances higher positioning accuracy, and ensures ball screw lifetime (X-axis travel＞4m, Y-axis travel＞3m)
    • The minimum distance between the spindle center and the Z-axis roller way not only shortens the cutting lever arm but also significantly improves cutting rigidity.
