What are the ways to reduce deformation of gantry milling machine

What are the ways to reduce the deformation of the gantry milling machine? Let me have a simple look:

1. Control temperature rise

After adopting a series of measures to reduce the heat source, the condition of thermal deformation will be improved. However, it is usually very troublesome, even impossible, to completely eliminate the internal and external heat sources of the gantry milling machine. Therefore, the temperature rise must be controlled through excellent heat dissipation and cooling to reduce the influence of the heat source. The more useful method in the middle is to force cooling in the fever part of the gantry milling machine. You can also heat the low temperature part of the gantry milling machine to make the temperature of each point of the gantry milling machine tend to be uniform, so as to reduce the warping deformation caused by the temperature difference.

2. Reduce fever

The key heat source for thermal deformation in the interior of the gantry milling machine should be as far away as possible from the host.

3. Improvement of headstock

Regarding the spindle box of the gantry milling machine, the thermal deformation of the spindle should occur on the vertical target cut by the tool. This can minimize the influence of the thermal deformation of the spindle on the machining diameter. Choose quality machine tool accessories to look for Titanium. In terms of structure, the distance between the spindle center and the spindle to the ground should be minimized to reduce the total amount of thermal deformation. At the same time, the temperature rise of the spindle box should be uniform to prevent the spindle from deforming. Skew appears afterwards.

4. Improved organization of gantry milling machine

Under the same fever conditions, the structure of the gantry milling machine also has a great influence on the thermal deformation. For example, the single-column organization previously used by the gantry milling machine may be replaced by the double-column organization. Due to the symmetry of the control, the main axis of the double-pillar tissue after heating occurs in addition to the translation of the vertical target, the deformation of other targets is small, and the axis movement of the vertical target can be easily compensated by a coordinate correction amount.

The above is the method to reduce the deformation of the gantry milling machine, I hope it will help you.
