CNC milling machine GMC2540 CNC Gantry Machining Center
cnc gantry milling machine is a machine tool that uses milling cutters to mill workpieces.
CNC Gantry Machining Center can process planes (horizontal, vertical), grooves (keyways, T-slots, dovetails, etc.), toothed parts (gears, spline shafts, sprockets, helical surfaces (threads, Spiral grooves) and various curved surfaces.
In addition, it can also be used for machining the surface of revolving body, inner hole and cutting work. Due to the multi-tool interrupted cutting, the productivity of the milling machine is high.

Structural features:
1. The bed of the gantry type machine center is made of high-strength cast iron and has a closed frame structure with stronger load-bearing capacity.
2. There is a balance cylinder on the left and right sides of the headstock of the cnc gantry milling machine. The automatic synchronous balance is realized through the gas-liquid conversion device, and no external power source is required to ensure the smooth and stable movement of the headstock.
3. CNC Gantry Machining Center adopts high-speed, high-precision, high-rigidity heavy-duty spindle unit, with strong axial and radial bearing capacity.
4. The Z axis of the gantry metal cnc milling machine adopts a rectangular hard rail, and the guide rail pair is quenched and plastic-coated and precisely scratched to ensure the kinematic characteristics of the machine tool and the rigidity necessary for cutting.
5. The 5 Axis Gantry Milling Machine Z-direction drive motor has a power-off braking device.

In order to reduce thermal deformation, the following measures are usually adopted in the structure of gantry milling machine:
1. Controlling the temperature rise After taking a series of measures to reduce the heat source, the situation of thermal deformation will be improved. But it is usually very difficult or even impossible to completely eliminate the internal and external heat sources of the gantry milling machine. Therefore, the temperature rise must be controlled by good heat dissipation and cooling to reduce the influence of the heat source. Among them, the most effective method is to force cooling in the heating part of the gantry milling machine, or it can be heated in the low temperature part of the gantry milling machine, so that the temperature of each point of the gantry milling machine tends to be consistent, which can reduce the warpage caused by temperature difference.
2. To reduce the main heat source of thermal deformation when the gantry milling machine generates heat, the heat source should be separated from the host as much as possible.
3. Improvement of the spindle box For the spindle box of the gantry milling machine, try to make the thermal deformation of the spindle occur in the vertical direction of the cutting tool. This minimizes the effect of thermal deformation of the spindle on the machining diameter. In terms of structure, the distance between the center of the main shaft and the main shaft to the ground should be reduced as much as possible to reduce the total amount of thermal deformation.
4. Improve the gantry milling machine Under the same heating conditions, the gantry milling machine also has a great influence on thermal deformation. For example, the single-column mechanism used by the gantry milling machine in the past may be replaced by a double-column mechanism. Due to the left-right symmetry, the main axis of the double-column mechanism after being heated has little deformation in other directions except for the vertical translation, and the vertical axis movement can be easily compensated by a coordinate correction amount.
