Determining the required tonnage is a crucial step before any bending operation. Our tonnage calculator allows you to quickly estimate the force required based on the material, sheet thickness, bend length, and tooling configuration.
This tool is invaluable for preparing your bending operations, verifying that a press brake has sufficient capacity, and selecting appropriate tooling. It also helps minimize programming errors, reduce workshop trials, and preserve the lifespan of punches, dies, and the machine itself.
