Bending Sheet Steel With A Small Radius

Bending sheet steel with a small radius. In other words if you re bending 1 8 sheet use a tool with a 1 8 radius to form the inside of the bend. If you re bending 0 020 thick material use a 0 020 radius. 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. To ascertain your k factor inside radius and material thickness expressed as a decimal you should use an bend allowance chart.

As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be. Generally speaking the thicker a piece of sheet metal is the wider the internal bend radius will have to be. 24 gauge 0 025 0 635 mm 0 265 6 73mm. 22 gauge 0 031 0 787mm 0 265 6 73mm.

Minimum bend bend radius. For most applications with stainless steel or aluminum you can get away with a zero radius bend on anything under 0 050 thick. As you can see below the difference between 3 and 6 bends is rather significant. You can use this to put a perfectly clean 90 degree inside bend in steel bar or sheet of any width use a cutting disc to slot down through the plate at the.

The thickness of the metal. It should be noted that the bend angle is also halved from 30 to 15. 24 gauge 0 025 0 635 mm 0 2 5 08mm. 24 gauge 0 025 0 635 mm 0 5 12 7mm.

The bend step is the number of bends which will be used to form the radius.
