A metal-cutting machine includes a bed with slideways, a movable unit with a headstock and a drive for moving it in a horizontal plane over the bed slideways, a work table with stock guides for moving the pallets carrying the workpieces and provided with coupling members for gripping the pallets, at least one platform installed before the work table in the direction of movement of the workpieces and is provided with stock guides for the pallets. The platform and work table are arranged for movement relative to each other in a horizontal plane so that when the pallet moves to and from the working position the stock guides of the platform serve as a continuation of the stock guides of the work table. The machine also incorporates a device for gripping the pallet in order to move it over the stock guides of the platform and work table to and from the working position. The pallet-gripping device is installed on the movable unit of the machine at the side facing the pallet with the workpiece, the drive moving the pallet to and from the working position with the aid of the pallet-gripping device being constituted by the drive of the movable unit of the machine. |
