摘　　要：将XB4450仿型铣床改造成四轴三联动数控铣床,并采用交流伺服驱动。配上数控分度头可以加工齿轮、蜗轮等复杂机械零件,同时应用数字化全闭环控制方法,使其具有很高的加工精度。The XB4450 imitating milling machine was transformed into four axes three linkages numerical control milling machines driven by AC servo. The numerical control index head was adopted, so the milling machine can process the machine parts as the gear, the worm gear, with the digital loop control method, it has high processing precision.
