Good morning to all,
I need to cut a flat test for a traction test from a thick sheet up to 6mm. cutting must be done online, in a sheet metal production plant. I had thought of a laser or plasma thermal cut, but I'm afraid the thermal alteration of the material could be significant. Alternatively, you can use a shear (shaped, because the profile is concave) or a die cutting machine.

Is someone able to suggest me some producer to contact on the second street, or for the shears/fustellar?

Thank you very much

even a cut with a shear alters the material
you have a "unscrupted" area in the proximity of the cut edge that would alter (in some measure) the result of the traction test
Think of using a waterjet?

the request is of an "auxiliary implant". if we offer a waterjet with the plant complications of control, management and disposal water pull me cuppitielli behind.. .

Mah... control of a waterjet or laser/plasm are virtually identical
in plasma as in laser you still have operational and maintenance practices to respect, other than waterjet but not less important
on water disposal, I do not expose myself. I know that in many plants the water is closed and is only integrated.
Moreover, in the laser/plasm you have a nice fume extraction system that still needs its maintenance and disposal of the aspiring products

Hi.
tampo fà in the workshop from a friend we did some aluminum tests for traction tests.
we "recut" them under a cnc frieze (recommended by guard-rail pieces).

Usually, even at the suggestion of technical norms and relative to the test of traction I tell you that normally you take a hydraulic chisel with inclined blade and cut into pieces the material obtained from the main process processing and then it is brought on a working center to realize the classic form according to the traction test.

guillotine shears can also have concave/convex blades.

look for manufacturers of:
- guillotine shears
- headers

in Italy there are several small and large builders of plants for the processing of sheet metal and certainly someone sells it to you the shears
