I believe that there is- Roper Whitney makes a tool, which I have
wanted for years, called a Radius Master.
It is a corner rounder for sheet metal.

It has different radius dies, so the one machine can do everything
from 1/8" to 1" radiused corners, with up to 3" dies available on
special order.
It is hideously expensive- which is one reason you probably have never
seen one.
I have never seen one used, and I doubt they sold very many new.
I believe they are close to 5 grand new, now.


I have an old 24" DiAcro "Radius Brake" which has interchangeable bars for
bending sheet metal in a smooth curve at a specific radius. It must not have
been very popular as I see little reference to it and have found no
literature on it.

I wonder why these haven't been readily available? It wouldn't be a
difficult tool to make -- heck they make them for paper and thin metal
like the Lassco.

It could be constructed like a corner notcher but obviously to create
a convex round.

A tool and die selection for several sizes.

Oh well -- thanks -- I needed to ask.

I would think that a modern CNC punching machine (eg. Amada) would
typically be equipped with such dies.

Maybe that's what these "cruciform" dies are used for..

anyone know for sure? I've not had a chance yet to play with such a
machine.
