  • Box-in-Box structure design enhances machine rigidity and ensures the best accuracy performance for high-speed processing

    The crossbeam and saddle are designed as box-in-box thermal symmetrical structure which gives good force flow transmission and prevents deflection.
    With perfect structural rigidity, the machine gives the best accuracy performance of high-speed machining and reduces thermal deformation and weight deformation greatly.

    Symmetrical force flow design 

    X/Y/Z axis are designed with symmetric force structure .Dual driving units and equivalent uniform force at gravity center can ensure optimal surface quality and prolong tool life.


    The lowest gravity center in the world
    Zero distance between gravity of the moving parts and the driving plane makes the gravity center closer to the driving plane.  The machine stability could then be improved and the best machine rigidity could be ensured.
    X/Y/Z axis driven by linear motor
    X/Y/Z axis driven by linear motor provides excellent dynamics and static rigidity. The rapid feedrate of the axis is up to 60m/min and the acceleration is up to 0.5G ~ 0.7G. The structure is simple and easy to maintain without transmission
    power loss.

    Two-axis head driven by direct drive motor
    Excellent surface finish contour could be enhanced thanks to the high torque direct drive motor system of two-axis heads.Small size appearance is suitable for complex curved surface machining and the advantages include low error, high resolution and high speed.

    Counterbalance system 
    The counter balance system is designed with close-loop which include high pressure components. This system could compensate the gravity effect and minimize the load of the motor. Excellent static and dynamic rigidity could be ensured. 

    Optimized working area
    Heightened column design provides larger Z-axis travels which is perfect for mold makers
