摘要： A milling machine is designed for machining the curved surfaces of propelling screws and comprises a turntable with the screw set on it and a fixed gantry along the horizontal guide of which two carriages move to mount bars capable of vertical movement. The lower end face of each bar gets in contact with a vertical cylindrical insert turnable round its axis. The lower end face of the insert is made inclined to the horizontal plane. An overarm is connected to the lower end face of the insert. The longitudinal axis of the overarm is parallel to the lower end face of the insert. A spindle head with a milling cutter held therein is connected to the overarm coaxially to its longitudinal axis. The spindle head is capable of turning round the longitudinal axis. A milling cutter rotation drive is mounted on the overarm.
