Crowning System

The crowning system is a motorized or hydraulic axis which adjusts the curvature of the lower beam automatically during the bending phase. The crowning effort is calculated from a specific formula and from machine's setting adjustments. Depending on the type of part to be bend (bending on one side of the machine rather than bending on the center of the press brake…..) corrections can be made.   CNC press brake hydraulic crowning table – Some press brakes come from the factory with hydraulic crowning already built in. Hydraulic crowning uses hydraulic cylinders located in the bed of the machine. As the cylinders are filled with hydraulic pressure, they exert an upward force on the bed of the machine to compensate for deflection. Modern hydraulic crowning systems often feature what is known as dynamic crowning. Dynamic crowning provides a unique benefit of monitoring inconsistencies and resistance during the bending process, allowing for it to make real time adjustments to correct not only inconsistencies in the press brake but inconsistencies in the material as well. – Some press brakes come from the factory with hydraulic crowning already built in.

Press brake crowning is a critical compensation technology that addresses deflection issues in sheet metal bending operations. When bending long workpieces, press brakes naturally deflect under load, creating inconsistent bend angles across the material length.   Mechanical wedge crowning system - By far the most common solution to compensating for deflection is mechanical crowning systems. Mechanical crowning systems are installed in place of a bottom tool holder, as they also serve this function. They typically feature either mechanical or hydraulic clamping as options. They also typically feature different drive designs, from analog to digital readouts and from hand crank assemblies to CNC motors. Mechanical crowning systems can typically be outfitted to the press brake at the time of purchase, as well as after the purchase in the form of a retrofit. Mechanical crowning systems vary in design, accuracy, and ease of use from product to product.   If your press brake didn't have a hydraulic crowning system, then a mechanical crowning system will probably be the solutiont what you need to compensate for deflection.
