Bending

Bending is a process of folding and bending flat plates, which follow the cutting process in the whole processing chain. The workpiece is placed on a concave die with a V-shaped opening. The wedge cutter (upper cutter) presses the workpiece into the V-shaped opening and in this way bends the sheet to the desired Angle.

Three point bend

Hollow bending, the upper knife will be pressed into the opening of the die, but not to the bottom of the die. The workpiece only rests on the two edges of the die during the whole bending process. The bending Angle is determined by the depth of the upper knife into the die. Hollow bending can achieve different bending angles without changing the mold.

Dynamic deflection compensation technology

KRRASS has been using dynamic deflection compensation technology on MB8 series bending machines for a long time. This unique compensation system automatically adjusts the radian of the working table during bending. The new generation dynamic deflection compensation system performs real-time correction with state-of-the-art sensors. Users can obtain accurate and constant bending results even when machining parts longer than 3 meters.

Accurate

Precision is the most important criterion for measuring the Press Brake. A slight deviation from the desired bending Angle is physically impossible to avoid. Either because the bending Angle is not accurate enough to begin with, or because the bending Angle varies across the entire bending length. In hollow bending, deflection compensation system can offset this defect. KRRASS employs a unique hydraulic dynamic deflection compensation technology on its Press Brake: the upper cutters and die die work in an arc to offset the deformations created during bending.
