CNC Press Brakes - Fast and Accurate Folding

Our skilled team applies the closest attention to detail at every stage so you can be sure your bespoke metal products are of the highest quality in accordance with our quality assurance system.

A CNC press brake uses high pressure to force a metal sheet or wire metal between two parts of a tool to create folds.

A die with a V-shaped groove forms the lower part of the press brake. The punch is the upper part, which presses the sheet metal down into the die, causing the metal to bend..

The angle of the die is slightly smaller than is required for the bend (for instance, a die angle of 85 degrees is used to produce a 90 degree bend). A CNC program precisely controls the punch stroke to force the metal down and bend it through the desired angle. For sheet metal, the press brake can exert a bending power of approximately 25 tons per metre of length.

Precision, accuracy and consistency is programmed in

The press brake is fitted with computer-controlled back stop gauges which position the metal sheet correctly to ensure each particular fold is formed precisely. The CNC program manages and adjusts the position of the gauges, enabling the operator to create a number of different folds to a high level of accuracy within the same program.
