Very stiff wear-free slide guiding guarantees utmost precision in slide movement. This is essential to assure the quality of the parts and provide long tool life, while achieving high production rates. Tool changeovers can be performed in a matter of a few minutes. The tool holders are self-centering by means of specially shaped receptacles, eliminating the need to adjust the die relative to the punch.

A precise indexing sequence is essential for production at high speeds. The systems gain flexibility and can be controlled independently due to the uncoupling of the slug feeding and finished part transfer functions. The NC servo drive controls the dial feed plate that provides both slug feed and part transfer. This way the slugs can be guided smoothly in front of the die without vibration.

The finished part removal function is driven by a second servo motor. Here too, the motion has been optimised. It consists of three phases: the part is picked up slowly, quickly transferred out of the punch area and gently deposited onto the exit conveyor.
