Rolling sheet metal radius.

Rounding edges with minium radius 2 mm is a necessity for good adhesion of coating or paint to protect against corrosion. Sharp inside bend radius in sheetmetal parts can cause material flow problems in soft material and fracturing in hard material. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. If copper has to be bent a factor of 1 5 must be used.

To solve this cmrp provides easy to use measurement calculators. Torn workpieces can then no longer be used. For example the minimum bending radius of aluminium is determined by multiplying the sheet thickness by a factor of 2. We also specialize in sheet metal bending and plate bending with a bending capacity up to 500 tons by 18 feet.

Rounding off sharp edges with radius cutters good and accurate rounding of steel constructions according to en 1090 iso 12944 iso 8501 or imo pspc is becoming more and more important in the metal working industry. When it comes to curved steel finding the precise measurements is a challenging undertaking. Bend radii minimum bend sizes. In this case the minimum radius equals the respective sheet thickness.

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. For most applications with stainless steel or aluminum you can get away with a zero radius bend on anything under 0 050 thick. These parts are rolled from 18ga sheet metal that was perforated and are rolled to an inside radius of 6. Crca inside bend radius equal to 0 65 times of sheet thickness is also enough.

Sheet metal rolling is just one of our specialties here at jorgenson metal rolling forming. But for harder materials e g. Protocase tech tip video. Recommended inside bend radius for sheet metal parts should be equal to material thickness.

For steel the factor is 1. This value represents the limit at which the material can still be bent without defects. If you re bending 0 020 thick material use a 0 020 radius.
