Abstract: A tool system is provided that has a stamp or punch adapter including eccentrically positioned stamp receptacles. This system permits a simple exchange of tool inserts in the stamp adapter. These tool inserts are also usable in another tool system. The system also permits combining the stamp adapter with a stamp shaft, which can also be used in another tool system. These features permit stamping (and punching) with minimal tooling and retooling efforts.

Abstract: A method of discharging workpieces cut from a planar material on a processing machine. A workpiece discharge device has several holding elements to receive and carry respective workpieces. After receiving a cut workpiece, the discharge device is moved to a waiting position outside and adjacent a processing region of the machine, and may then be moved back into the processing region to receive a subsequently cut workpiece before being moved to an unloading station.

Abstract: A machine tool that includes a workpiece support and a punching die. The punching die includes a support surface, for supporting a workpiece to be processed, and a discharging slope. The discharging slope is configured such that a workpiece part, severed from a workpiece supported on the support surface of the punching die, is displaced, in at least one of a rotational, tilting, or linear movement, from a processing position at least partially overlying the discharging slope toward a removal position on the discharging slope. The discharging slope is also configured such that a workpiece part, severed from a workpiece supported on the support surface of the punching die, is directed, in a sliding movement, toward a discharging position located beneath the support surface and adjacent the punching die.
