What is a bending machine?
A press brake is a machine tool primarily used for bending sheet metal and sheet materials such as metal. It forms predetermined curves by clamping the part between a corresponding punch and die, providing precise manufacturing for various industries.
A press brake is mainly used in the manufacturing industry to bend and fold metal sheets into desired shapes. This versatile machine harnesses the power of hydraulic or mechanical energy to transform flat sheets into complex shapes, enabling precision and efficiency in metal fabrication tasks.
Are a brake press and brake press the same thing? Yes, a brake press and a press brake are essentially the same machine. Both are used in metallurgy to bend and bend sheet metal into specific shapes. The terms are often used interchangeably in the industry, highlighting their identical functions and characteristics.
Pressure Brake Fundamentals
Press brakes are essential tools in the metal fabrication industry that facilitate the bending and shaping of sheet metal to create various structures and products. There are three main types of press brakes: mechanical, hydraulic and electrical. Each type has its unique features and benefits, so it is essential to understand these distinctions when choosing the right press brake for your operation.
Mechanical press brake
Mechanical press brakes operate using a mechanical drive system powered by a flywheel and clutch. The flywheel gains energy from a motor and then releases it to power the press ram. These machines are typically less expensive than their hydraulic counterparts, making them an attractive option for smaller shops with limited budgets. However, they often lack the precision, strength, and control that hydraulic or electric press brakes can provide.
- Advantages: Lower cost, simpler operation.
- Disadvantages: Limited accuracy, strength and control.
Hydraulic press brake
Hydraulic presses use a hydraulic system to move the ram, allowing for greater pressure and force during the bending process. This increase in power provides more precise bending and greater control compared to mechanical bending machines. Additionally, hydraulic press brakes can be easily adjusted to accommodate various thicknesses of metal and are capable of performing complex bends with one smooth motion. These machines tend to be more expensive, but are generally preferred for their greater performance and versatility.
- Advantages: Greater precision, control and strength, adaptable to different materials.
- Disadvantages: Higher cost, more complex operation.
Electric press brake
Electric press brakes use servo motors to control the movement of the ram, enabling fast, precise and energy-efficient bending operations. These machines offer several advantages over their mechanical and hydraulic counterparts, such as reduced energy consumption, fewer moving parts, and lower maintenance requirements. However, electric press brakes are often more expensive and may not provide the same level of force as hydraulic models.
- Advantages: Energy efficiency, greater precision and reduced maintenance.
- Disadvantages: Higher cost, potentially lower force capabilities.
By understanding the components and benefits of each type of press brake, you can make an informed decision when selecting the most suitable press brake for your shop.
Main components and functions
Frame and bed
The frame and bed are the basis of a press brake. They are made from strong steel designed to withstand the force exerted during the bending process. The base is a horizontal surface on which the workpiece is placed, while the frame supports the ram and die.
Hit and die
The ram and die are critical components in a press brake. The ram is a vertically moving part that applies pressure to the workpiece, causing it to bend around the die. The die is a specially designed interchangeable tool that determines the bend angle and radius. Common types of arrays include:
- V-dies : used for air bending and bottom bending
- U-die : suitable for U-shaped bends
- Gooseneck dies : designed for bending flanges or channels
Back gauge
The backgauge is an essential component of a press brake that ensures the workpiece is accurately positioned for bending. It consists of several fingers that align with the fold line, guiding the workpiece into the correct position. The backgauge can be adjusted manually or automatically to accommodate different flexure dimensions.
Controls
Press brakes use several control systems to manage and monitor the bending process. These systems range from simple manual controls to advanced CNC systems that provide accurate and consistent bending results. The control system's main functions include setting bending parameters, monitoring pressure, and ensuring the machine operates within its specifications.
Safety features
Safety is crucial when operating a press brake. Various safety features are integrated into the machine to minimize the risk of accidents and injuries. Some of these features include:
- Light curtains : infrared beams that create a perimeter around the machine, stopping it if the beam is interrupted
- Security guards : physical barriers that prevent access to the ram and sow area
- Emergency stop buttons : easy-access buttons to immediately stop the machine in case of emergency
- Interlocks : prevent the machine from operating if the doors or panels are not closed properly
These key components and functions work together to ensure the efficient, accurate and safe operation of a press brake.
Different Types of Press Brake Machine
How many types of press brakes are there?
There are several types of press brakes, but the most commonly used are hydraulic down-motion press brakes and CNC press brakes, depending on the classification method used.
Let's learn more about this through the following classification methods:
1. Classified by source of bending force
According to the source of bending force, the press brake is divided into: Mechanical press brake, Pneumatic press brake, Hydraulic press brake, Servo-electric press brake.
(1) Mechanical press brake
For the mechanical press brake, the vertical movement of the ram is driven by a crank mechanism that is driven by the flywheel.
(2) Pneumatic press brake
And the pneumatic press brake uses air pressure to move the ram.
(3) Hydraulic press brake
The hydraulic press brake uses two synchronized hydraulic cylinders to move the ram.
(4) Servoelectric press brake
The servo electric press brake uses a servo motor to drive a ball screw or belt to apply force to the ram, causing it to move vertically. Before the 1950s, mechanical brakes were the dominant choice in the global market.
However, with advances in hydraulic technology and computer controls, hydraulic presses have become the most widely used option across the world.
2. Classified by Operation
From another point of view, the press brake can be divided into: manual press brake, hydraulic press brake, CNC press brake.
(1) Manual press brake
It is the most common type among the various bending machines, also known as plate brakes. Manual press brakes require manual adjustments of dimensions and bending angles during use.
It consists of a work table, supports and a fixing plate. The work table is mounted on supports, which consist of a base and a pressure plate.
Manual press brakes are more complex to operate than other types of press brakes, so it is necessary to confirm the bend size and angles before starting mass production.
After completing a mass production batch, adjustments to the size and bending angles must be made to continue production.
(2) Hydraulic press brake
The hydraulic press brake uses the principles of hydraulics to generate a considerable amount of force that can be used to manipulate the material being worked.
Hydraulic presses are more advanced than mechanical presses. They use hydraulic fluid, which is controlled by a hydraulic pump, to exert pressure on the piston, causing it to move and create the bending action. The pressure exerted is proportional to the amount of fluid pumped, which allows precise control of the bending process.
(3) CNC press brake
An electro-hydraulic servo press brake is a type of sheet metal processing equipment that offers high precision and efficiency. The following components are included in its design:
- Machine structure
- To knock
- Workbench
- Oil Cylinder
- Hydraulic proportional servo system
- Position Detection System
- CNC Controller
- Electrical control system
The CNC press brake is a highly efficient and precise sheet metal processing equipment that performs bending by controlling the stroke of the ram and the back gauge.
The operator only needs to input the number of parts to be bent and the bending angle for each step, and the CNC press brake will carry out the bending process according to these specifications.
Advanced CNC press brakes adopt hydroelectric servo systems and grid rulers to form a closed-loop control system, ensuring high control accuracy, bending accuracy and repositioning accuracy.
With advancements in technology, electro-hydraulic servo synchronization technology is being adopted to upgrade the system, providing numerous advantages.
- CNC press brakes use an electro-hydraulic servo system to control the synchronization of two cylinders, with the international standard grid ruler to achieve full closed-loop control. It has high precision synchronization, high bending precision and high repeat positioning precision.
- The press brake is equipped with an automatic hydraulic clamp or quick clamp for the upper die and a lower plug die, according to customer requirements, to reduce labor intensity and improve production efficiency.
- The back gauge can be extended to 6 axes, and the crowning is automatically adjusted by the controller, providing convenience and accuracy.
- The press brake is equipped with components such as Bosch-Rexroth valve block from Germany, linear motion guide and ball screw manufactured by BLIS, Taiwan HIWIN or other international companies to ensure positioning accuracy.
- The upper die, which comes in different lengths, can be assembled to a certain width to meet special part requirements.
- An automatic cylinder crowning system overcomes the impact on part quality caused by ram deformation and guarantees the straightness and curvature angle of the final products.
3. Sorted by Sync
Classified by synchronization, the hydraulic press brake can be divided into:
- Synchronized torsion press brake
- Electro-hydraulic synchronized press brake
- Hybrid press brake
4. Sorted by Movement
Classified by movement, hydraulic presses can be divided into:
- Press brake in upward movement
- Press brake in downward movement

Working principle of bending machine
How does a hydraulic press brake work?
In simple terms, the press brake works by using the relative movement of the punch and die, which are fixed on the upper and lower work table, to achieve the bending of sheet metal materials through hydraulic transmission.
A more detailed explanation:
The hydraulic press brake incorporates numerical control technology, servo and hydraulic technology.
The left and right cylinders are driven to extend and retract by controlling the valve action. This movement causes the press brake ram to move up and down.
The synchronous action of the ram is achieved through the combination of grid signal feedback and proportional valve flow, which is controlled by the CNC system.
The numerical control system also has a screen for human-machine interaction and simulation of the bending process.
The CNC system controls the opening of the two valves on the left and right cylinders.
If necessary, the flow in the cylinder can be redirected by the servo valve, causing the upper beam to move linearly in the vertical direction.
The amount of movement is determined by the newly measured pulse count.
The signal from the CNC controller is converted into a hydraulic signal to control the valve action through the servo valve.
Each cylinder in the hydraulic system has its own independent control circuit, servo valve and filling valve.
Bending the part at different angles can be achieved in a single operation.

Advantages and disadvantages of press brake
Advantages of the press brake
(1) Suitable for small batch and multiple variety production:
The press brake allows versatility with a single punch and die assembly, making it suitable for producing a wide variety of materials and parts.
(2) Low cost and long service life of bending dies:
Each set of bending molds costs only a few thousand yuan, and the manufacturing process is simple, eliminating the need for repeated testing.
Additionally, each set of dies can last at least 10 years, reducing the overall die manufacturing cost.
(3) Capable of producing “S” and “U” shaped parts:
In stamping molding, the production of “U”-shaped parts is particularly challenging. Press molding requires a certain amount of rebound, which can lead to difficulties in mating the punch and die.
The bending machine, on the other hand, solves this problem by performing multiple bending operations.
(4) Ideal for trial production of new products:
The versatility of a press brake allows the production of parts with different shapes, sizes and angles using a single punch and die set.
This makes it ideal for trial production of new products without incurring additional costs.
(5) Able to form a variety of polygonal shapes with different heights:
The bending machine can produce multi-fold parts with different edge heights by adjusting the material and angle settings.
(6) Deflection compensation function:
When bending long parts, there may be a significant deviation between the forming angle of the middle and sides, leading to irregular angles.
The press brake, however, has a deflection compensation function that allows you to adjust the angle in each position, ensuring straight bending and reducing the need for manual adjustments and repairs.
This speeds up the production of long parts, reduces labor intensity and improves product quality.
Disadvantages of the press brake
(1) Requirements for Material Thickness
The materials used in bending must meet certain thickness requirements.
As a general rule, materials no thicker than 50mm can be easily bent, but those thicker than 50mm require substantial bending force.
Press brakes commonly used in companies have capacities of 400t, 300t, 160t and 80t.
(2) Risk of fracture during bending
During the bending process, the edges and corners of the material may develop burrs or oxide layers, which can cause the material to crack or fracture during bending.
This makes ensuring the quality of the final product a challenge.
(3) Recoil during bending
Indentation is a frequent quality problem that occurs during bending. In some cases, the chosen bending die may not be suitable or an appropriate die set must be used, resulting in unavoidable indentation.
In these cases, an additional grinding process is required and the thickness of the polished material and parts must be tested.
Deep indentations can result in discarded materials and parts, increasing costs.
(4) Sliding during bending
During bending, some materials may slip, causing the folded piece to come out.
Square materials typically do not face this problem, but irregular materials can easily slip, resulting in non-compliance with process standards.

Press Brake Tools
What are press brake tools?
Press brake tools are an essential component of press brake machines that help ensure the precision and quality of final bent parts. It consists of a punch and a die that are used to shape and bend metal sheets or plates into the desired shape.
Tools are made from high-strength materials, such as hardened steel, to withstand high pressures and forces during press brake operations.
There is a wide variety of shapes and sizes available to suit different applications and workpieces. The die used for forming has a cavity, while the die used for separation has a blade edge.
Press brake tools consist of several components that work together to bend and shape sheet metal. The most important elements in press brake tools are punches and dies, as they directly perform the bending process.
Punches
The punches, also known as the top tool, are attached to the top of the press brake. These tools are responsible for applying pressure to the metal sheet, forcing it into the dies. Punches are available in different shapes and sizes, depending on the desired bend and the type of material to be processed. Some common puncture types include:
- Straight punches: Used for simple bends with large radii.
- Gooseneck punches: Designed to make sharp angled turns and U-shaped channels.
- Hemming punches: Used to bend sheet metal at a continuous angle to create a flat surface.
Matrices
The dies, also known as the bottom tool, are located at the bottom of the press brake. They form a cavity or groove to accommodate the sheet metal and punch. When the punch presses the metal sheet into the die, it forms the desired bend. Some common types of matrices are:
- V-Shaped Dies: The most common type, ideal for bending a wide range of materials and thicknesses.
- U-Shaped Dies: Used to create channels and flanged shapes in sheet metal.
- Displacement dies: Designed to perform Z bends or double bends in a single operation.
Careful selection of punch and die combinations is crucial to achieving desired results. Factors such as type of material, thickness, radius of curvature and tonnage of the press brake must be considered when choosing the appropriate tool. Proper maintenance and handling of tools are also essential, as they directly impact the quality of the finished product.

Instructions on how to use a press brake:
As an example, here is a simple introduction on how to use a hydraulic press brake to manufacture Q235 carbon steel:
First, connect the power, turn on the switch on the control panel and press the pump to start.
You should be able to hear the sound of the oil pump turning. (The machine will not start working at this time)
Pay attention to the stroke adjustment for press brake operation.
This must be tested before bending. Make sure there is a gap equal to the thickness of the plate when the upper punch is at the bottom of the lower die, otherwise the mold and press brake may be damaged.
Stroke adjustment can be carried out via electrical quick adjustment or manual fine adjustment.
For V-width selection, the width of the V-opening should normally be 8 times the thickness of the plate. For example, when bending a 4mm board, you should choose a die with a 32mm V-opening.
The back gauge adjustment generally has electrical quick adjustment and manual fine adjustment.
Lower the pedal to start bending. You can stop the machine at any time by releasing your foot.
If you release your foot, the press brake will stop and you can continue bending by pressing the switch again.
