Maximum dimensions are 2980 x 1200 mm. Maximum sheet thickness for all other steel is 6 mm. Maximum sheet thickness for aluminum and stainless steel is 6 mm. If the product contains one or more sharp bends use the dimensions from the sharp tables for all bends in.

In a previous bending basics article you mention a material s tensile reduction percentage used for calculating the minimum inside bend radius of various metals. Bend radii and k factors for 304 stainless steel sheet metal components share. Determining the minimum internal radius for a bend in sheet metal. The thickness of the metal.

Hi my machine bending in radius 3 mm k faktor is 0 45 is it correct or not. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. There are a two major factors that affect how tight you can make the internal radius of a bend in a piece of sheet metal. Generally speaking the thicker a piece of sheet metal is the wider the internal bend radius will.

To keep it simple i also use a 2 mm inside radius. Recommended minimum bend radii for steel and aluminum. Let s say i have a 2 mm thick sheet and i want to bend it. You described a rough rule to find a steel s minimum bend radius.

The following tables showing the minimum bend radius allowable in air bending process for aluminum and steel or stainless steel. It is possible to choose other bends if you require but additional lead time and tooling charges may apply. I have a sheet metal bending table for most gages of sheet metal but not many for ss which is why i was asking this forum. Since commercial sheet metal bending can be done with less concern for stresses caused during forming operation the radius can be near zero for thin sheet metal.

We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. 22 gauge 0 030 0 76 mm 0 5 12 7mm. Aluminum where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t.

Table 1 preferred recommended 90 degree bend radii for various sheet metals. A general guideline the minimum metal bend radius is approximately equal to the material thickness. Divide 50 by the material s reduction percentage as specified by the material supplier subtract by 1 and then multiply by the plate thickness. Category thickness minimum bend bend radius.

22 gauge 0 030 0 76 mm. Steel 304 1 mm thick. Steel american iron and.
