The structure of the gantry machining center is very different from the traditional machining center equipment with similar stroke. Generally, the X axis stroke is more than 2 meters. It is recommended that users use the CNC gantry. First of all, workpieces above 2M are generally large. The rigidity and stability of the machine tool must be guaranteed to ensure the machining accuracy and the service life of the gantry machining center machine tool. In addition, from the perspective of processing stability, cost, practicability and use status of the machine, gantry type is generally recommended.
The structure of gantry machining center equipment is more stable. Its gantry type double column structure is more solid and stable than the C-type single column structure, and its accuracy and machine rigidity are more guaranteed. The overhang of the machining box of the gantry machining center is shorter than that of the C-shaped steel, which ensures that the original machining accuracy of the gantry machining center is higher than that of the C-shaped steel, and it can be used for a long time.
What are the factors affecting the machining accuracy of gantry machining center
Gantry machining center screw vacancy: the positioning accuracy of the gantry machining center directly affects the processing accuracy of the workpiece, and the temperature is crucial to the positioning accuracy. If there is no machine with constant temperature working environment, it is necessary to let the machine idle before processing every day to make the machine temperature match the outside temperature. When the gantry machining center processes, it is necessary to frequently check the reverse position of the lead screw.
