8' or 6' brake press...something 3' to 4' will do for robotics.

We would like a new one or something in like new condition. It will be used mostly for R&D. Keep in mind this is not for robotics, we might use it on the robot but only as another piece of equipment from our sponsor.

Don, thanks for the info. All we are looking to do are 90 degree bends. So this should be fine.

The main item we need this for at the moment is a 40" wide 0.090" thick aluminum 5052.

How do you get these numbers? at what gauge?
As I mentioned before, we do have a Promecam RG 103, which is a 100 ton press. However, all we do on it is bend 3/4" thick steel and all very high quantities when we run it. I got a quote to get some Gooseneck Punch dies and a Staged Block die, however these dies are over $3k. Not to mention we would have to change dies on the machine every time we want to do something for R&D. I am trying to weight our options and determine what is best. If we got the dies we would be able to make bends up to 100 inches wide which is a plus.
Does any one have experience with the brakes from Baileigh?
I am looking at:
http://metal.baileighindustrial.com/...brake-bb-4816e
and:
http://metal.baileighindustrial.com/...-brake-bb-4816
But, even the heavy duty one can only do up to 50 thousands. Unless I am not looking at the specs correctly.
Any other suggestions?
