In the intricate landscape of modern manufacturing and fabrication, one indispensable tool stands out – the press brake machine. Whether you’re shaping metal sheets with precision or bending them to exact specifications, the press brake machine is the silent hero behind countless products we encounter in our daily lives. 

Modern press brakes have increased automation and CNC controls, allowing for greater precision and repeatability compared with traditional machines.  It’s not unusual for contemporary devices to come with multi-axis computer-controlled back gauges, optical sensors, and programmable controls that use real-time data to inform the machine when to make adjustments without an operator needing to intervene.

Introduction To Press Brake Machines

What is a Press Brake Machine?

A press brake is a fabrication machine that shapes metal sheet and plate.  It works by creating predetermined bends in material placed between an upper and lower die.  Force is applied to the die and the metal bends at the desired point. Depending on the machine and the type of die being used, there are a variety of shapes that can be created.

The basic design of most press brake machines starts with a robust press frame made up of two outside uprights, a worktable across the bottom and connecting plate across the top. There are two tools, one attached to the table and the other attached to the ram.  The ram consists of a whole steel plate positioned above the worktable between the uprights; the upper die is attached to the ram’s lower edge and cycles downward to force the workpiece into the lower die and initiate the desired angle.  A press brake is usually described by the type of force that’s being applied; there are mechanical, pneumatic, hydraulic and servo-electric press brakes.

Basic Understanding About Typical Press Brakes

(1) A mechanical press brake, which was the most popular option until the 1950’s, uses a flywheel with an electric motor.  The operator employs a clutch that engages the flywheel and powers the crank mechanism forcing the ram down.  Mechanical presses offer both speed and accuracy, making them an efficient machine for simpler jobs.

(2) A hydraulic press brake employs two synchronized hydraulic cylinders that are attached to the uprights and move the ram.  A servo-electric press has a servomotor that propels a ball screw or belt drive, which then applies pressure to the ram.  Finally, a pneumatic press operates thanks to air pressure that forces the ram into the workpiece.

(3) Among modern machines, pneumatic and servo-electric press brakes are best suited for applications that require a lower amount of force.  Hydraulic press brakes are extremely accurate and do not consume a lot of energy, making them a good option when sustainable operations are a priority.  Another benefit is that the action of the ram can be halted on command, making them extremely safe.

(4) Modern press brakes have increased automation and CNC controls, allowing for greater precision and repeatability compared with traditional machines.  It’s not unusual for contemporary devices to come with multi-axis computer-controlled back gauges, optical sensors, and programmable controls that use real-time data to inform the machine when to make adjustments without an operator needing to intervene.

What Types of Dies Can Be Used With Press Brakes?

Factors To Consider When Choose A Press Brake Machine

There are many factors to consider before purchasing a bending machine. Below I will provide some practical guidelines from the most basic aspects.

How To Select A New Press Brake

  • Tonnage: This is referred to as the bending capacity of a press brake. Hence, is the most important consideration to be made while selecting the press brake for your facility:
    • Type of Material
    • Thickness of Material
    • Length of the Material
    • Process Employed
    • Die Opening

    If you are unable to calculate the tonnage of the machine then it is always better to approach the manufacturer whom you are considering. They will help you calculate the bending force of every task.

  • Length of the Material to be Processed: Next, consider the maximum length of the sheet metal to be processed. If you wish to bend the sheet metal by employing multiple stations on the press brake then you need to alter the length of each station. For maximum efficiency, you can select a press brake that allows you bending short and long sides effectively through two stations. This will reduce your processing time.
  • Daylight or Open Height: The choice of open height will depend on several factors such as the type of metal bending to be performed, the sheet metal bending tools used, and the stroke needed for the activity. For instance, if a customer is using a press brake with standard daylight, he may find difficulties to move the finished part while bending flanges that are large in size.
  • Deflection: You must consider the deflection that a machine may undergo. For instance, a 5-foot machine will endure four times less deflection in the ram and bed than a 10-foot machine when subjected to the same load.


In addition to the above-mentioned factors, it is important to check on other factors such as the desired angular accuracy, type of tooling used, flange width, and the workpiece used. By now you might have understood how a press brake can be an asset to your facility. Hence, it is important that you source it from a reliable manufacturer or supplier.
