Abstract: A method for operating a device for automatically feeding bars or half-finished bars to a machine tool such as a computer numerical controlled (CNC) lathe, and automatically unloading workpieces machined from the bars includes loading a bar through the rear into a spindle of a lathe via a loading/unloading device including an integrated bar feeder device, a magazine configured to receive at least one bar to be machined, and a loading/unloading beam; machining the bar in a machining space in front of the lathe; and unloading the bar by actuating the loading/unloading beam after the bar has been completely machined in order to recover a bar end in the machining space and to transfer the bar end to a trash bin for residual material and rejects. The loading/unloading beam is capable of successively or simultaneously moving at least in a vertical Z axis direction and a horizontal Y axis direction.

Abstract: The device for automatically feeding blanks or half-finished workpieces to a machine tool, more particularly a CNC lathe, and automatically unloading the machined workpieces is composed of a gantry loader having an integrated feeder device that allows loading bars into the rear of the spindle of the lathe, thereby constituting a universal automatic feeding device. Furthermore, the latter more particularly allows a controlled removal of the bar end after all workpieces have been machined from a respective bar.
