Common Pass Height adds Advantages

Operations varying from large automotive and tandem line dies, transfer press dies to small progressive dies should be set up to run at a common feed or pass height. Generally, this should be as high as possible for the following reasons:
 
1. Presses operated near their maximum shut height adjustment wherever possible maximize adjustment screw engagement, which avoids uneven screw wear.
 
2. A common pass height will avoid the need to make vertical adjustments to the feeders or loaders in both coil and cut blank fed presses.
 
3. Making the pass height as high as possible provides for steep scrap chutes to improve dependable scrap discharge.
