What press force is needed ?
"Andre Majorel" wrote in message ... Thanks for the hint, Ned. How do you know what press force is needed for a given job ? Specifically, punching holes about 1 cm² in 1 mm steel or 3 mm aluminium. -- André Majorel URL:http://www.teaser.fr/~amajorel/ "Marque nouvelle. Dans le stock. Les navires de FL, les Etats-Unis. Service de client exceptionnel garanti." You can reduce the amount of force by grinding an angle on the punch. |
