ughh,.. how do you cut stainless steel plate?
I went thru this a few months ago. Someone suggested "burning" it by
putting a disposable saw blade in the table saw. It worked fine, but do clean up any sawdust that's laying around since the fireworks are impressive. The theory is that the blade has time to cool as it moves from the cutting point around the perimeter, but the SS doesn't. I used a 6" plywood blade that had been expended trying to cut Masonite. The cut edges do have to be cleaned up with a grinder. For drilling 1" holes in 1/4" plate, I got to 1/2" but that was the limit for my 1/4 hp drill press. The local machine shop charged a minimal fee and used a machine that's bigger than my car. Roger http://home.earthlink.net/~derbyrm "ready aboot!" wrote in message ... It's 1/8in plate, dull and greasy, probably 304. I buggered the bandsaw blade, then two "hardened carbide, blah, blah" jig saw blades, a file, a diamond file, then got a beefy angle grinder and gouged grooves in it and forced it through what was left of the bandsaw metal blade, dressed it fairly straight with the grinder and ground it to shape on a big bench sander with gnarly grit paper. This took several frustrating hours. There was course language and graphic violence. It won't fit in the power hacksaw because of it's initial shape. Is there an easier way? We don't have a pneumatic metal stamper, cutter, shear thing locally. Thanks as always. |

I do not know what you are exactly cutting? So suggesting the appropriate
method may not be practically feasible. However, be careful when shearing and stamping stainless steel. I had to replaced chain plates that were originally made by shearing and stamping. I detected hair line cracks around the shearing and punching. The probabilities of finding hair line cracks after shearing, stamping and punching are about 50%. It's like flipping a coin in the air. The hair line cracks will develop with time and exposure to saline atmosphere. Conversely if the part is not subject to stress , impact or heavy load stamping, shearing and punching will save you money. Depending what you are making, sometime it is safer to use flat bar stock drill and cut to length with the appropriate cutting compound. If you have access to a shop that uses plasma cutting you may be able to get an affordable quote for getting your work done. ..568291$x96.331154@attbi_s72... I went thru this a few months ago.
