In order to make a metal roller you need an advanced machine casing from Industrial Craft 2.

Now you're starting to see the problem. In order to make an advanced machine casing, you need refined iron plates.

And you need an advanced machine casing to make the metal cutter and metal roller, therefore it is
My guess at this problem is that the recipe was changed, from the original which I found on the IC2 wiki.

This recipe instead uses basic machine blocks which only require refined iron.
Hopefully this can be resolved.
