The three-axis guide rail is the roller linear guide of Japan THK, which is wear-resistant, easy to maintain, large carrying capacity, and high precision; the three linear axis screw and servo motor are directly connected through the coupling, and the synchronization function is good. Rapid traverse and feed speed up to 40m/min

Features of new structure design of gantry machining center

1. The three-axis guide rail is the roller linear guide of Japan THK, which is wear-resistant, easy to maintain, large carrying capacity, and high precision; the three linear axis screw and servo motor are directly connected through the coupling, and the synchronization function is good. Rapid traverse and feed speed up to 40m/min

2, X, Y, Z, B four coordinate detection components are directly measured by German Heidenhain grating ruler, forming a closed loop control, positioning accuracy and repeat positioning accuracy can reach 0.008/0.005mm

3. The overall layout of the machine tool design is that the vertical and horizontal bed is in an inverted T-shaped structure, the column moves horizontally left and right (X-axis travel 1000mm), the headstock moves up and down (Y-axis travel 900mm), and the worktable moves longitudinally back and forth on the bed. (Z-axis stroke 900mm). The bed adopts an integral forged bed with good rigidity;

4. The column is a gantry frame type front hanging box, which has good rigidity, average force, and good dynamic performance without confusion in accuracy;

In the structural design advantages of the new high-speed machining center, the high-speed electric spindle is the core component of the high-speed machining center, because the electric spindle must have a high speed to be able to achieve high-speed machining, and for the micro milling of the mold (milling cutter diameter is generally 0.1～ 2mm), a higher speed is required. Most high-speed machining centers or milling machines used for mold processing still use servo motors and ball screws to drive linear coordinate axes, while the swing of the rotary table and the swing of the fork-shaped spindle head are combined with Rotation and other motions have been widely implemented by torque motors. Therefore, in the next few years, it is believed that the machine tool industry equipment of high-speed machining centers will definitely become a popular model of machine tool equipment for the development of the industry.
