The 4 pillars of press brake tonnage limits

May 3, 2015

By:

To ensure you always work within the tonnage limits of your press brake and tooling, first calculate how much tonnage you need. Second, identify your tooling’s load limits. Third, calculate the sinking tonnage limit, which, if exceeded, can embed tooling into the ram or bed. Fourth, determine your press brakes’ centerline load limit.
