slitting spring bronze

Lloyd E. Sponenburgh · 2013-05-20T17:09:40+00:00

Ok, 'solutions guys'... I have some 0.010" phosphor bronze (spring temper) in rolls 6" wide x 80" long. I need to cleanly slit some 3/8" strips x 80" from this without any edge distortion. We tried taking one a sheet metal house that had a long scissor-type shear, and it cut it, but also curled the edge too much for our application. It has to wind flat in a coil when finished. I've tried sheet metal hand shears without much joy, a nibbler just chews it, and sawing it on anything we've got is impossible. We must not heat it. Also cost is an issue, or I'd have it done at a waterjet and laser house down the road, but they want a couple-hundred just to set up a job. For only five strips, that's not in budget. A virgin roll has perfect edges, and rolls tightly. The mill that makes the rolls from larger sheet stock cannot go narrower than 1". Any ideas? Thanks, Lloyd

Apparently with cheap Chinkalloy cutters, stacking two 1" cutters end-to- end doesn't get you anything smaller... I tried. The stupid math keeps coming out 1 TIMES 2 instead of 1 divided by 2. But they're cheap cutters... probably defective cutters. I'm sure that good American cutters would divide by length when stacked.

The VAR who actually _does_ the conversion of that stock probably doesn't know how to use slitting cutters. And they aren't wealthy enough to have cutters "stored in the back", they have to keep theirs in use.

But I still believe them when they say they cannot slit anything narrower than 1", I tend to believe them.

Andy is a slitting genius, and a nice guy. Give him a call and I'm sure he'll have a suggestion.
