In the field of metal processing, sheet metal bending is an extremely critical process, which determines the final shape and structure of metal products. And to achieve efficient and accurate sheet metal bending, choosing the right bending equipment is crucial. Today, we will discuss in depth the two common sheet metal bending equipment – press brake and finger brake, to help you make a clear understanding of how to make the right choice according to their own needs.
Press brake is a widely used power equipment in the metal processing industry, its working principle is to place the sheet metal between the matching convex and concave moulds, through the application of strong pressure, so that the convex and concave moulds together, so as to bend the sheet metal into a specific angle. This precise bending process is able to meet a variety of complex metal processing needs, and is an important means of manufacturing various types of metal parts.
Hydraulic Press Brake :Hydraulic press brakes use hydraulic cylinders to control the movement of the slide. It is very powerful and can easily cope with metal sheets of various thicknesses. At the same time, its speed is controllable, and it can be flexibly adjusted according to the material and thickness of the plate in the bending process to ensure the accuracy and quality of the bending. Moreover, the hydraulic press brake has good stability and can maintain stable performance during long working hours. Its key components include hydraulic cylinders, slides, clamps, moulds and punches, which work together to achieve efficient and accurate bending operations.
Mechanical Press Brake: The mechanical press brake relies on a mechanical flywheel to generate the force required to bend the sheet metal. It has the advantage of being fast and ideal for mass production. When manufacturing metal parts of the same specification in bulk, a mechanical press brake can greatly increase productivity and reduce production costs. Its main components are flywheel, slider, fixture, mould and punch. Through the clever design of the mechanical structure, it achieves a high-speed and stable bending process.
Servo-electric Press Brake：servo electric press brake is driven by servo motors, which makes it a qualitative leap in control accuracy. It can achieve extremely precise positioning and bending control, to meet the needs of metal processing with high precision requirements. At the same time, the servo electric press brake has low energy consumption, which meets the requirements of modern industry for energy saving and environmental protection. Its main components include motors, sliders, fixtures, moulds and punches, and the advanced servo motor technology gives it excellent performance.
Electro-Hydraulic Servo PRESS BRAKE
finger brake, also known as box and plate press brake, is a machine tool specially designed for metal fabrication and sheet metal processing. It is mainly used for bending thin metal sheets, and is capable of generating a variety of angles and shapes on demand, with three-dimensional parts like boxes and trays being easily produced. finger brakes have a wide range of applications in industries such as HVAC (Heating, Ventilation and Air Conditioning), metal fabrication, and sheet metal working in general. Its main components include fixtures, segmented finger parts, moulds and punches, which work in conjunction with each other to achieve accurate bending of thin sheet metal.
finger brakes, as a special type of box and disc press brake, are unique in that they have segmented finger parts or rods. These finger parts can be flexibly adjusted to different bending needs, demonstrating great versatility and precision when making complex custom sheet metal parts. Whether it is a complex shape with multiple bends or a sheet metal part with special specifications, the finger brake can cope with it.
Press brake is suitable for larger, thicker plates for accurate bending. For example, in automotive manufacturing, the need to bend thick steel plate into the shape of the body frame, the press brake will be able to rely on its strong pressure and precise control, along a single axis for consistent bending, to ensure that the size and shape of each component meets the strict standards.
finger brakes, on the other hand, excel at creating complex box, disc and tray shapes with multiple bends and edges. In the case of electronic products, which often require multiple bends and fine edges, the finger brake can take full advantage of its strengths by flexibly adjusting the finger-shaped parts to achieve the precise production of complex shapes.
finger brakes equipped with CNC technology offer a high degree of precision in terms of bending angle, depth and length. Precise control through computer programmes ensures that the dimensional error of each bend is extremely small, meeting the needs of industries with stringent requirements for precision, such as the aerospace industry.
finger brakes do not have high-end CNC systems, but with adjustable finger parts, they also offer good precision when shaping and bending custom shapes. When creating small metal crafts, finger brakes can bend a variety of unique shapes with precision, depending on the design requirements.
The press brake usually needs to change the mould when facing different bending angles and shapes. The process of replacing the mould is often cumbersome and requires a certain amount of time and manpower, which to a certain extent affects the production efficiency.
finger brake’s finger-like parts can be quickly positioned, the operator only needs to make simple adjustments, you can quickly switch between different bending operations, greatly improving the flexibility and efficiency of production.
press brakes are more suitable for bending thicker materials thanks to their powerful hydraulic or mechanical power. In the construction industry, thick steel plates used to make large steel beams require the strong pressure of a press brake to achieve the bend.
finger brakes are designed for thinner materials, and their structure and power system are better suited to handle light sheet metal. When making ventilation ducting for thin sheet metal, finger brakes can handle it with ease.
finger brakes are ideally suited to the mass production of consistent parts with the same bending specifications. In mass production of automotive parts, the press brake can follow a pre-set programme to produce a large number of parts with the same specifications quickly and accurately, increasing productivity.
finger brakes, on the other hand, are more suitable for small batches or one-off designs, and they can flexibly produce products in a wide range of shapes and sizes to meet individualised production requirements.
Many press brakes are equipped with CNC control, the operator only needs to enter the program on the computer, the machine can automatically complete the complex bending sequence, greatly improving production efficiency and accuracy.
finger brake, although some of them have similar manual CNC control, but overall, it is still mainly manually operated, requiring the operator to have a certain degree of experience and skills.
press brakes are capable of handling a wide range of bending tasks, but perform much better at simple bending. When manufacturing a large number of simple shaped metal components, the press brake is able to do the job efficiently and consistently.
finger brakes are highly versatile when making complex shapes, especially those with multiple bends and edges. In the production of artistic shapes of metal decorations, finger brake can show unique advantages.
The different bending requirements of a press brake may require more specialised tooling, which are more expensive to design, manufacture and maintain, and will increase production costs to some extent.
The adjustable finger parts of a finger brake reduce the need for additional tooling and lower tooling costs, making it an affordable option for small businesses or individual studios with limited budgets.
