Press Brake Tonnage Calculator (It’s FREE to use)

Maybe you are a manufacturer of the press brake.

Maybe you are a sheet metal processing factory and now you need to buy a press brake.

You may wondering how big press brake do I need? And you urgently need to quickly calculate the required bending tonnage. By using the press brake tonnage calculator we have made for this purpose, you only need to enter the sheet metal thickness, the bending length and our recommended vee opening width, the calculator will show the required bending force.

Of course, if you want to know exactly how the tonnage of the press brake is calculated, you can refer to this article. It details how to get the required press brake tonnage in three different ways.

Let’s start by using the press brake tonnage calculator that we have made for you.

New Bending Force Calculation Method

If the width-to-thickness ratio V/S is not equal to 9 and the diameter-to-width ratio is not equal to 0.16, the above calculator will no longer be applicable.

Please check the new method for calculating the bending force of a press brake machine. The following bending force calculator should be used.

Inner R Formula

The following formula can be used to calculate the press brake bend radius:

Inner R Formula

Allow minimum bend edge size B (mm)

165° 135° 120° 90° 60° 45° 30°
0.51×V 0.55×V 0.58×V 0.71×V 1×v 1.31×V 1.94×V
