Bending Sheet Steel With A Small Radius

The more bends the smoother the roll.

Bending sheet steel with a small radius.

Minimum bend bend radius. To ascertain your k factor inside radius and material thickness expressed as a decimal you should use an bend allowance chart. If you re bending 0 020 thick material use a 0 020 radius. 24 gauge 0 025 0 635 mm 0 265 6 73mm.

Choosing the right bend step is important because while more bends means a smoother radius it also means a more time consuming and technically difficult procedure. 0 017453 x 90 x 0 020 0 33 x 0 024 0 0438558984 inch bend allowance. As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be. The bend step is the number of bends which will be used to form the radius.

The hardness of the metal. For most applications with stainless steel or aluminum you can get away with a zero radius bend on anything under 0 050 thick. 24 gauge 0 025 0 635 mm 0 5 12 7mm. It should be noted that the bend angle is also halved from 30 to 15.

As you can see below the difference between 3 and 6 bends is rather significant. 24 gauge 0 025 0 635 mm 0 2 5 08mm. Generally speaking the thicker a piece of sheet metal is the wider the internal bend radius will have to be. The thickness of the metal.

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.
