High-Speed Heavy CNC Double Column Machining Center GMM-2217

① Base structure
Compared with the double-guideway design, the rigidity is 50% higher;
Compared with the four-guide ways design, it is more symmetrical and evenly distributed, reducing the power loss caused by the resistance of the multi-guideway slider;
3m wide worktable, 2.1m base linear guideway. It is best ratio span of 0.7.
② Gantry moving nut structure
The X-axis is driven by a moving nut, and three-point support is used in the middle to maintain the rotation accuracy of the ball screw rod. At the same time, the load capacity is large, and the cutting vibration resistance is good. It can improve the dynamic characteristics of the machine tool and increase the accuracy, stability, and service life of the machine tool.
③ Square ram
Bigger dimensions 500*500, the original size is 460*460. It is a more heavy-duty design;
The built-in direct connection design reduces the power transmission consumption from the spindle motor to the spindle.
④ Slide features
The large-size and heavy-duty design ensure that the upper part of the ram is firmly hugged by the three elongated sliders, and the lower part is supported by the four standard sliders.
⑤ Nitrogen counterweight
Reduce the load of the motor and the bearing force of the ballscrew, increase the life of the ballscrew and the motor, and the acceleration of the Z axis to ensure processing accuracy.
⑥ Beam structure
Stepped L-shaped design improves rigidity;
The concave C-shaped structure has better bending resistance;
Large section design;
Finite element analysis.
⑦ Ballscrew support frame system
⑧ Column structure
The 1.28m ultra-wide design of the column reduces the overall cutting vibration and makes the machine tool stable.
