The modularity of the PRONIC tapping solution provides you with the choice of a mechanical or servo driven system. However, each of these technologies has its own application cases. The use of the servo driven tapping unit makes sense for: dies running with very large press stroke, over 500mm (20”) dies with very short press stroke, less than 50 mm (2”) dies with short Shut Height tapping units running in transfer presses Fineblanking applications Multi slide presses Stand alone / off line tapping Progressive dies running with several different press strokes. The Mechanical tapping unit is the preferred choice for most progressive dies, and it is sometimes also a good choice for tranfer presses.
