introduction： Cutting-milling method(plunge milling)Also known as...ZShaft milling method，It is one of the most effective machining methods to achieve high metal cutting rate。Surface machining for difficult materials、Grooving machining and machining with large tool overhang length，The machining efficiency of insert milling method is much higher than that of conventional face milling method。In fact，When a large amount of metal material needs to be removed quickly，Milling method can shorten the machining time by more than half。In addition，Milling machining also has the following advantages：①It can reduce the deformation of the workpiece；②The radial cutting force acting on the milling machine can be reduced，This means that worn spindles of shafting can still be used for insertion milling
