Gantry machining center T-20L

Gantry machining center T-20L

  • Gantry machine series are widely used in aerospace, automobile, precision mould and parts processing industry, to provide high reliability of the mechanical system and  software interface with diversity, selectivity, easy operating, thoroughly make high-precision dreams come true.

    Large columns and beams supporting box structure, ensure the best of rigidity. The beams adopt hatchback design, the dilated sliding wide the stress surface, the average center of gravity  is close to the head center of the beam, all these is to achieve better precision of movement and ultra strong ability of heavy chips.  The overall structure highlights the unique high stability, professional design of center symmetric spindle system. Equip the exact configuration of the spindle, spindle motor, ball screw and variable heavy oil pressure cylinder position, to avoid unbalance torque generated deflection temperature, so as to maintain optimum accuracy condition. Z axis variable  heavy oil cylinder uses suspension support , close to the moving center of gravity position, with the optimal configuration of the center of the symmetrical spindle and drive screw motor , to eliminate unbalanced torque, to ensure the micro feed of the fixed line and long-term precision. Y-axis square rail slide with all travel sustained  is to ensure the best stability.(X,Y,Z hard rail)
