In various engraving industries, we are often focused on tablet engraving, such as door lines, acrylic billboards, etc., there are some need for three-dimensional engraving materials. In this case, we need a 4 axis CNC router machine to operate. The so-called axis of the CNC router refers to the three coordinate axes of XYZ plus the rotating shaft. In fact, whether it is a 3 axis or 4 axis CNC router machine, it has all the shafts, but the different 3 axis CNC routers are used in the process, only three axes are running, but the four axes are more flexible, they can start at the same time And run four axes. 4 AXIS CNC Router Machine produced by Igoldencnc Factory is a four-axis CNC router designed to handle three-dimensional materials.
