1.The main foundation parts such as base, sliding seat, work table, column and headstock are made of high-strength cast iron; the base is box-type structure, and the compact and reasonable symmetrical rib structure ensures the high rigidity and bending and shock absorption performance of the base parts; The A-type bridge straddle column and the internal grid-shaped ribs ensure the rigidity and precision of the Z-axis strong cutting. The base parts are resin sand molding and aging treatment, which guarantees the stability of the long-term performance of the machine tool.
2.The X/Y/Z guide rails are heavy-duty 45# linear roller guide rails, which have the characteristics of high speed, high rigidity, low friction, low noise, low temperature rise and other characteristics, and cooperate with automatic forced lubrication to improve the precision life of the machine;
3.Z-direction plus nitrogen balance system ensures smooth and stable headstock movement; Z-direction drive motor has power-off braking device;
4.The X, Y and Z directions are fed by high-precision and high-strength internal circulation double nut preloading large lead (4012) ball screw, and the feed speed is high; the drive motor is directly connected with the lead screw through the elastic coupling. The feed servo motor directly transmits the power to the high-precision ball screw without backlash, ensuring the positioning accuracy and synchronization of the machine tool;
5.Adopting Taiwan's high-speed, high-precision, high-rigidity spindle unit, the axial and radial bearing capacity is strong, and the maximum speed can reach 8000rpm;
