Abstract: The invention relates to a machining unit in which the pieces are carried by an electric turning spindle radially arranged on a turret with a vertical axis of rotation. On rotation of the turret the pieces are successively introduced into machining stations, arranged peripherally around said turret and comprising tool support means. A large space is thus available around the periphery of the machine for housing the tools. The electric turning spindles are adapted to selectively hold the pieces at any fixed angle, thus permitting not only turning operations but also other machining operations on fixed pieces.
