Hi all.
I've just bought a set of 6mm x 1250mm capacity 3 roll initial pinch rolls and i'm having trouble with the pre bending. After 4 or 5 attempts at getting the radius right, i'm making a mess of the rolling in between. I am trying to roll a 180 degree segment with a 400mm outside rad @ 600mm long in 5mm plate.
I am chalking a line at 200mm in from either end and then pre bending and rolling to this line (I stop the rolling when the line is directly in between the 2 pinch rolls). Once the 2 ends are at the right radius I then start to roll the remainder of the plate by rolling back and fourth in small increments and changing direction when the chalk lines are in between the drive rollers.
I am doing something wrong because i'm left with something resembling a 50p piece!!
Anyone out there got any advice please?
