PURPOSE: A workpiece supply device of an NC(Numerically Controlled) lathe is provided to easily control chucking regardless of the size of the outer diameter of workpiece since the installation locations of upper and lower pliers change according to the outer diameter of workpiece. CONSTITUTION: A workpiece supply device of an NC lathe comprises a turret mounting body(10), upper and lower slide units(20,25), and upper and lower workpiece pliers(30,35). The upper and lower slide units are slidably coupled through the groove(12) of one side of the turret mounting unit. The upper and lower slide units are slidably coupled to the groove of the turret mounting body. The upper and lower pliers are coupled to the upper and lower slide units and make contact with the upper and lower parts of workpiece to fix the workpiece from upper and lower sides.
