Product Description

Heavy Duty CNC Gantry Milling Machine GMF3025R Gantry Machining Center Precision Parts Processing Milling Machine 

Gantry Machining Center Main Feature

Gantry milling machine 5 axis machining center cnc inherits the advantages of rigid rigidity, structural symmetry and strong stability of the traditional gantry machine frame. It introduces the international advanced dynamic rigid design concept and optimizes the design of moving parts. The machine tool has large torque and good fast response characteristics, and is suitable for various mechanical processing fields such as automobile, mold, aerospace, military, and hardware.


Heavy Duty CNC Gantry Milling Machine Overall layout
The overall layout of the machine tool is fixed-column fixed-column gantry frame structure, the base is fixed, and the workbench moves X-direction on the base; the column is fixed on the base, the beam is fixed on the column, and the sliding seat moves in the Y direction on the beam; the ram is in the sliding seat Move in the Z direction.

Structural Features of CNC Parts Processing Gantry Machining Center Milling Machine:
High rigidity and long-term precision retention:

1. The main large parts of the machine tool: the base, the workbench, the column, the beam, the sliding seat and the ram are all made of high-quality resin sand, high-strength high-quality cast iron, with a complete heat treatment process to eliminate residual stress and arrange enough reinforcement. The plate ensures sufficient strength, rigidity and high stability of the machine.
2. The XY axis adopts heavy-duty roller guide rail with strong rigidity and good dynamic precision.
3. The three-axis transmission adopts the Taiwan brand large-diameter grinding double-nut ball screw, which has compact structure, stable movement and high precision. The screw support is supported by a precision screw rod, and the two ends are pre-stretched to eliminate the loss of precision caused by thermal elongation.
4. The beam adopts a stepped structure. The cross section of the beam is large, the span of the guide rail is large, the distance from the center of the main shaft to the surface of the guide rail is short, the turning torque is small, and the structural rigidity is good.
5. The high-rigid Taiwan brand gantry special spindle, which is lubricated with grease, can make the spindle bearing have constant and reliable lubrication, which is economical and environmentally friendly and realizes long-term maintenance-free.

High precision, high dynamic response characteristics:
1. The spindle adopts high-precision angular contact ball bearing to achieve high rigidity and high spindle rotation accuracy.
2, XY axis roller guide, high precision, large load. The friction is low, the low-speed crawling phenomenon of the machine tool is reduced, the positioning accuracy is good, and high dynamic response characteristics are obtained at the same time.
3. The Z-axis adopts a dual-motor drive structure, and its dynamic response speed is higher than the traditional nitrogen balance and hydraulic balance structure, with stable operation and high precision.

high efficiency:The spindle speed can reach 5000rpm, and the three-axis rapid movement can reach 10/12/10m/min.

Large processing range:Compared with the same specification machine, the machine's 2.5m door width ensures a wider processing range.

Design For Quality

Structure:CNC Gantry Type Milling Machine Center

The structure of machine tool is analyzed with ANSYS at all stages from foundation design to guarantee of high-speed and high-precision continuous machining. A simulation test for deformation produced when the center of machine tool bears load is conducted to guarantee excellent bending rigidity of machine tool.
