The device (1) for sensing the position of the work-piece (3) to be turned pushes and detects the "zero" position (2) of the work-piece. Situated on the lathe turret (4), attached by means of a support plate (5) to one side of the tool-holder disc (4'), it also comprises a pedestal (7), a pusher head (9) coupled behind the pusher head (6) on its side opposite to that of the work-piece (3), and generating an electrical signal indicating the position (2). The lathe turret (4) slides in direction Z and the head (6) pushes the work-piece (3) up to a position stop in the chuck (11). The tool-holder disc 4' revolves and the turret carries out a movement "z" in reference to said "zero" position of the work-piece (3). <IMAGE>
