PURPOSE: A workpiece flow device of a machine tool is provided to improve productivity by freely moving a workpiece without additional transferring device and adjusting the stroke of a cylinder of a rotating device and to improve the quality of a product and reliability of consumer by reducing production cost. CONSTITUTION: Sprockets(103,104,105) are formed on both ends of a shaft(102) having friction rollers(101) on one face of a base(128). A sprocket(111) formed on a hydraulic motor(112) is connected with a chain(113) at one side of the sprocket(103). A shaft(115) having a fixing block(107) is fixed on both ends of the shaft(102). A turntable(108) for fixing the shaft(115) is formed on the fixing block. A pinion gear is formed on the outer face of the shaft(115). If a workpiece enters a transfer device, the friction rollers are driven by the chain and the sprocket(103). Then, the workpiece touches a stopper on the friction rollers, and the hydraulic motor is stopped. Upon rotating the pinion gear by a cylinder, the turntable rotates 180 degrees with the workpiece. Therefore, the stroke of the cylinder is adjusted.
