Instructions: Input data into the blue boxes for your material and punch & die configuration. This estimates the tonnage required to complete a 90° bend.
DISCLAIMER: Actual bending force is affected by many factors such as friction between the material and the die, material thickness, material strength variations, rolling direction of the steel, work hardening and other parameters. This estimator calculates a force representative of the press brake requirement for air bending. Sizing of a machine or available die width should allow for up to 20% additional capacity. Garant Machinerie makes no guarantee of actual force required to make a bend in a specific part.
