What is the rotary axis CNC router?

Rotary axis CNC router is also called 4th axis CNC router who refers to these wood carving machine with rotary device. And it mainly processes cube or cylindrical work pieces. During the processing of the 4th axis CNC router, it is not necessary to repeatedly rotate and process the work piece manually to reduce the number of clamping times and complete the processing of the work piece at one time. Compared with ordinary 3 axis cnc router, 4th axis CNC machines reduce manual workload and improve production efficiency. In addition, since the tools of the rotary axis can be processed in layers, it is possible to ensure higher processing quality. Besides that the rotary axis can also realize the processing requirements of local processing without being limited by the size of the object.
