Problems solved by technology

Five-axis linkage CNC machine tools have always been restricted by western developed countries. They are expensive and maintenance costs are high. Once a collision occurs, it will cost a lot
Most of the domestic manufacturers only produce small and medium-sized five-axis machine tools, and there are few large-scale five-axis linkage machine tools, and the control method rarely achieves true five-axis linkage. Low collision avoidance factor
