Calculate the Press Brake Tonnage for Any Part

Every time a new part needs to be bent, there always seems to be a small trace of doubt: “will we have enough tonnage to bend it?” Bending sheet metal is all about breaking the molecular structure of the metal. The idea is to provide at least enough power to achieve “plastic deformation.” This type […]

Heat Treatment to Improve Tooling Durability

When manufacturing high quality press brake tools, selecting the correct materials and shape are only the first steps in the process. ROLLERI then improves the durability of our tools by hardening them. But hardening is just a small part of the process when we talk about resistance to compression and buckling. It helps, but it […]

Bending Types – Air Bending (or Partial Bending)

Today, “air bending” is the most frequently used bending technique thanks to the improvement of modern press brakes and their CNC’s, which can better manage the sheet metal springback. This name comes from the fact that there is always air between the sheet metal and the die bottom. It is also known as “partial bending” which […]
