Gantry structures, Y axis use simultaneous dual motor and drive, X, Y, Z axis with circular rail (formula type linear guide can be chose), steady transmission, high precision.
The running of axes X and Y is driven by servo motor and ball screw shaft and the punching position is controlled by double axes numerical control system.
