Rotary Axis CNC machine tool is a CNC equipment that adds a rotating axis (A/B/C axis) on the basis of traditional three-axis CNC, and realizes the machining of complex surfaces such as cylinders and spheres. Support 360 ° rotation processing, complete complex surfaces (such as threads and reliefs) in one clamping, reduce multiple positioning errors, and improve concentricity and surface smoothness; Automated continuous processing eliminates the need for repeated adjustment steps; Not only suitable for rotating workpieces made of various materials such as wood, metal, and stone, but also suitable for high-end needs such as sculptures, shaft parts, and precision molds.
