Bending brake not bending crisp edges - why?

[BTromblay]

Hi,

To help with your issue, you can try this. If you pre-thin the material at the bend line, you can get a crisp bend in a machine like yours. To thin the bend line, you can use two tight radius dies in a bead roller, pullmax or with a corking tool by hand. A simple experiment in your material will tell you "how far" to thin, for the tight crisp line you are looking for.
