Blanking of 4mm SS Strip
Blanking of 4mm SS Strip
(OP)
Does anyone know about the blanking of 4 mm SS strip.We have SS strip of 1250mm X 336mm X 4 mm. We would like to do blanking of this sheet (Blank size = 19mm X 300 mm). Is it possible to do blanking of this strip? What will be the machinery(capacity of press) & tools requirement for blanking this strip?

RE: Blanking of 4mm SS Strip
Here is a formula I use to determine tonnage of the press.
F= .7(thichness)(cicumference)(UTS).
For your application using 304 SS and in inches
F= .7(.157 in)(25.12 in)100000lbs/sq in
F = 275958 lbs
F= 138 tons
