Following these precautions will ensure safe operation of the press brake and high-quality machining results. If in doubt, consult a professional or the equipment manufacturer.
What is a folding machine
A folder is a precision machine tool used to bend and fold metal. Unlike traditional press brake machines that use punches and dies, folding machines use a unique operating concept.
Folding machines use upper and lower beams to clamp the workpiece to ensure its stability. The upper and lower beams are located above and below the workpiece respectively, and are clamped by a hydraulic system. In this way, the workpiece is able to maintain a firm position on the table of the folding machine.
During the operation of the folding machine, a third beam is also introduced, called the folding beam. This beam is mounted on the side of the machine and is able to swing. The swinging of the folding beam is carried out along the desired folding line, thus realizing the folding of the metal. The angle and position of the folding beam can be adjusted according to the requirements of the workpiece to obtain the desired folding shape.
By using a folder, the operator can precisely control the metal folding process. A control system on the machine tool allows the operator to set the motion parameters of the folding beam, such as swing angle, speed and position. The adjustment of these parameters can be optimized according to specific folding needs to ensure the best folding results.
Features of the folding machine
There are various levels of folders, but they all follow the same sequence to airbend to the desired angle: position -> clamp -> bend. The process is ideal for flexible applications, as the tooling is not specific to the desired material thickness or angle. The "universal" cutter geometry allows unlimited angular possibilities and reaches maximum machine capacity and height. Thanks to the unique process of folding the swing beam, these tools should last for many years. Use a flat tool to bend the flange to the correct angle, eliminating scratches or slippage on the workpiece. Not only does this mean higher quality parts, but it also means virtually zero tool wear.
There are many types of folders. On systems equipped with segmented clamping tools, new parts can be set up by rearranging the tool segments on the tool rail. Machines without an automatic tool changer still simplify the setup process by telling the operator where to place the tool stations. This common tool enables quick changeover between parts and makes it easy for a single employee to program, operate and set up machines for any compatible part.
The clamping tool of the folder allows the folding beam to be bent at an acute angle for hemming applications. This acute angle is then positioned under the clamping tool foot to close the hem to a specific height. This height can be selected for parallel hems, teardrop hems, or even open hems used in assemblies.
When a part needs to be formed into a large radius, the same tool can be used on a folded beam to smoothly make incremental bends until the desired radius is reached.
Application range

Bend Radii and Flanges
Both folding machines and press brake machines are capable of creating radii and hems, but they do so differently. The folding machine can produce any radius without special tools, and the bending process is invisible from the outside. In contrast, press brake machines require special hemming tools, and producing radii through the bending process can be more difficult.
Therefore, although folding machines and press brake machines have similar functions, there are still significant differences in operation, set-up, material handling and tool wear. Understanding these differences is critical to choosing the right metalworking machine.
Working principle
The working principle of the folding machine is to realize the folding of the metal by clamping the workpiece and using the swing of the folding beam. The folding beams are oscillated in such a way that they follow the desired folding line so that the sheet metal is folded at the desired location. Folding machines usually use a hydraulic system or an electric drive system to provide the clamping force and the kinematic force of the folding beam to achieve precise folding operations.
The working principle of the press brake machine is to bend the metal plate by using the punch and the die. During bending, the punch applies force to bend the sheet metal to the desired angle, while the die provides support and shape constraints. press brake machines usually use hydraulic or mechanical systems to control the movement of punches and dies to achieve precise bending operations.
