These dimensions are all in relation to a 90 angle.
Minimum bend radius stainless steel sheet.
If the product contains one or more sharp bends use the dimensions from the sharp tables for all bends in.
We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.
Getting the actual minimum bend radius for your sheet metal typically requires more detailed knowledge of the alloy being shaped which comes with training and education in metal forming techniques as well as a familiarity with the material s used for a custom sheet metal form.
In steel between 0 5 and 0 8 in.
A general guideline the minimum metal bend radius is approximately equal to the material thickness.
The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels.
This tool allows you to determine tonnage internal radius v die opening and minimum flange you just have to insert the characteristics of the sheet metal to be bent.
Material bend radii and minimum bend size charts please note.
Maximum dimensions are 2980 x 1200 mm.
The gauge inside radius die opening and minimum flange length are all interconnected through different equations and relationships the air bend force.
The following tables showing the minimum bend radius allowable in air bending process for aluminum and steel or stainless steel.
Aluminum 5052 or 3003.
The bend radius you select may not be available if the geometry of the part will not allow us to bend with the specific tooling required to achieve that radius.
It is possible to choose other bends if you require but additional lead time and tooling charges may apply.
Being able to read a bend force chart is crucial for any brake press operator and sheet metal engineer.
An air bend force chart or force chart breaks down a number of key components of sheet metal bending in an easy to reference format.
The minimum bend radius data shown in these charts is measured to the inside of the bend.
The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase.
Thick grade 350 and 400 may have a minimum bend radius of 2 5 times the material thickness when transverse bending while longitudinal bending may require a minimum bend radius that s 3 75 times the material thickness see figure 1.
Maximum weight is 40 kg.
Discover all our calculation tools in the calculators section of the top menu.
Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend.
The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.
Maximum sheet thickness for all other steel is 6 mm.
