The 4-axis CNC Router machine refers to the computer numerical control equipment including X, Y, Z, and additional rotation axis. It has 3 straight coordinates and 1 rotating coordinate. 4-axis CNC Router engraving machines are usually equipped with rotating axes or rocking spindles, so they can contact the workpiece from different angles and effectively work, so as to realize the 3D processing of cylindrical, curved and circular surfaces.

The 4-axis CNC Router is divided into the rotary type and spindle swing type, including right rotary axis engraving machine (customizable front rotary device), 2D&3D CNC engraving machine, 3D stereoscopic engraving machine, four-axis CNC machining center, foam carving machine, spindle swing engraving machine, and lock hole machine. The 4-axis CNC Router is also known as 4-axis CNC wood router, 4-axis CNC router machine, best -axis CNC router, 4-axis CNC milling machine, 4-axis CNC machine, 4-axis milling machine, 4-axis CNC engraving machine, 4-axis CNC router engraver machine, 4th axis CNC router, 4-axis machining, 4-axis engraving machine, 4-axis wood CNC machine, 4-axis wood carving machine.

How does the 4-axis CNC Router work?

The first one is similar to the 3 axes CNC Router machine with X, Y, and Z axes, but it also includes a rotating device called A axis. The moving path is X-Z-A, Y-Z-A.

The other is a four-axis linkage CNC Router, which realizes 180-degree machining by swing the spindle. Its motion path is X-Y-Z-A, X-Y-Z-B, and X-Y-Z-C. 4-axis CNC router engraving machine, at the time of carving, according to 360 degrees, each step takes 0.000* degrees. At the same time, the high speed rotating spindle on the carving machine cuts the processed material fixed on the table by cutting tools according to the material processed. We can carve various 2D or 3D relief graphics and characters designed in the computer to realize automatic carving. In daily application, the 4 axis milling machine worktable can not only achieve plane engraving but also realize irregular 3D machining and 3D carving of the irregular workpiece.

How is a 4-axis CNC Router used?

The application of the 4-axis CNC Router machine includes drilling, milling, carving, cutting, slotting, and hollowing on wood boards (such as wave boards, MDF, composite wood, solid wood). It is also suitable for leather, foam, PVC, steel, aluminum, acrylic, EPS, copper, and other soft materials. Common solid wood: softwood, hardwood, modified wood. Common wood composite materials: plywood, particleboard, hard fibreboard, MDF(medium-density fiberboard), high-density fiberboard, blackboard, and so on. Mold industry: casting mold, foam mold, automobile mold, train mold, aviation mold, ship model, paraffin mold, etc. Sculpture industry: keel, Buddha, gourd; Woodworking industry: 3D(three-dimensional) wave board processing, solid wood door, cabinet door, craft wooden door, wooden screen, paint-free door, craft window processing, musical instrument board surface, panel furniture processing; Advertising industry: advertising signs, acrylic processing, logo production, plastic molding, various materials decorative parts production; Craft gift industry: stigma, bamboo tube, and so on.
