The principle of five-axis gantry machining center is to add two rotation axes A/C on the basis of the linkage of the three linear axes of X, Y and Z in the original CNC gantry machining center, so that the machining head can obtain two degrees of freedom to rotate (or swing) on the two linear axes of X and Z respectively. Under the control of the numerical control system, the above five axes realize five-axis linkage, so that the tool is always perpendicular to the machining surface of the workpiece during machining, and the so-called "normal machining" is realized. Therefore, it is especially suitable for machining workpieces with particularly complex surface shapes, but at the same time, the accuracy must be ensured by machining.

The difference between five-axis gantry machining center, three-axis gantry machining center and four-axis gantry machining center;

The so-called four-axis NC machining center usually adds a rotating shaft, which is usually called the fourth axis. The corresponding machining center is a four-axis machining center. The most effective machining surface of the machining center (three axes) is only the top surface of the workpiece, and the gantry machining center can only finish the four-sided machining of the workpiece with the help of the turntable. At present, the high-grade machining center is developing in the direction of five-axis control, and the workpiece can be machined with one clamping. If equipped with five-axis high-grade CNC system, you can also process complex spatial surfaces with high precision.
