[0001] This utility model relates to the field of four-axis machining technology, and in particular to a four-axis machining center. Background Technology
[0002] A four-axis machining center is an advanced CNC machine tool that adds a rotary axis (usually the A-axis or B-axis) to the three-axis machining center to perform more complex machining operations. Compared to traditional three-axis machining centers, four-axis machining centers can perform machining in four directions simultaneously, greatly improving machining efficiency and accuracy.

A moving plate 8 is threadedly installed on the threaded rods 6 and slidably installed on the guide rods 7. The threaded rods 6 are driven by the dual-axis motor 5, enabling... The rotation of the threaded rod 6 drives the moving plate 8 to move, which in turn causes the connecting plate 9 on the moving plate 8 to move the clamping and fixing plate 4.
