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.

摘要： While the roll being machined is in a rotary feed movement, and its groove arcuate central portion is machined by a tool rotated around a fixed geometrical center of the arc defining the central portion and subsequently receiving a radial feed, the bevel flanks conjugate with the profile central portion are machined alternatively by a shank cutter which is rotated in the groove radial section plane and simultaneously moved in the radial direction until the bevel flank being machined conjugates with the arc of the groove central portion. For this purpose, a slide housing the revolving table operatively associated with the roll drive and carrying guideways with a cutter head and a cutter mounted therein is arranged on the bed at its one side with respect to the means the for accommodation of the roll being machined, and a post having vertical guideways with a means for clamping the tool holder mounted therein is arranged at the other opposite side of the bed.
