1 . HT300 cast iron is adopted for the main foundation parts such as base, sliding seat, workbench, column and headstock; CNC Vertical Machine Center The substructure is a box structure, and the compact and reasonable symmetrical reinforcement structure ensures the high rigidity, bending resistance and damping performance of the foundation parts; A-span column and internal grid reinforcement effectively ensure the rigidity and accuracy of z-axis strong cutting; CNC Vertical Machine Center The basic parts are molded with resin sand and aging treatment, which provides a guarantee for the stability of the long-term service performance of the machine tool.
2 . The X, y and Z guide rails have the characteristics of high speed, high rigidity, low friction, low noise and low temperature rise change. They cooperate with automatic forced lubrication to improve the accuracy and service life of the machine tool;
3 . Z-direction counterweight is added for balance to ensure smooth and stable movement of headstock; The z-direction drive motor is equipped with power loss braking device;
4 . CNC Vertical Machine Center X, y and Z feed directions adopt high-precision and high-strength internal circulation double nut preloading large lead ball screw, with high feed speed; The drive motor is directly connected with the lead screw through the elastic coupling, and the feed servo motor directly transmits the power to the high-precision ball screw without back clearance to ensure the positioning accuracy and synchronization of the machine tool;
5 . High speed, high precision and high rigidity spindle unit is adopted, with strong axial and radial bearing capacity. 6 . The spindle adopts the central air blowing structure. When the spindle looses the tool, the central high-pressure gas is quickly used to clean the inner cone of the spindle to ensure the accuracy and service life of tool clamping;
