To keep the bend angle consistent over the full length of the part, a press brake needs a crowning system, either in the beam, or in the table.


The European & American style Press Brake tooling can make a high performance for sheet metal bends.



Bend lines are reference points for calculating the extended length and creating bend geometry. and You can control the precision for sheet metal bend lines.

Offset dies are designed to form two bends with one stroke. The measurement is needed as the in-to-out dimension from one plane to another. Talk to an engineer at JSTMT to discuss the application and required tonnages.

It depends on the type of lower die. An acute die is measured from center radius to center radius. A 90 or 85 degree die is measured from the theoretical intersection to theoretical intersection. Talk to an engineer at JSTMT for more press brake tooling details.
On a punch it is from the tools shoulders down to the tip of its radius. (Does not include the tools tongue) On a die it is from the tools base up to the top of the die (does not include tools tongue). Check with Power Brake Dies for more press brake tooling details.
The material thickness value is squared, multiplied by 575, divided by the die-opening width inch value and then divided again by 12 inches. The tonnage per inch is now calculated. You can then multiply the value by the bend length.
