This invention relates to a propeller milling machine, and specifically to a machine tool with milling cutters capable of machining the work in conformity with predetermined pitch and rake angles of propeller blades. The advantages of this invention are as follows: (1) It is possible to minimize the waviness of the machined surface, increase the pitch of machining, and shorten the distance of machining locus, with a remarkable reduction in the number of runs for machining operation. (2) The outer periphery of the propeller hub can be machined by the ball end mill. (3) It is possible to realize automatic propeller operation under numerical control.
