There are various different types of press brakes described by the means of force application. These are; pneumatic press brake, servo-electric press brake, hydraulic press brake as well as mechanical press brake. The operation Hydraulic presses brake is simply by hydraulic cylinders that are synchronized on the C-frames which moves the upper beam. In mechanical press brake, there is an addition of energy to a flywheel with a motor that is electric. The flywheel is engaged by a clutch in powering a crank mechanism which vertically moves the ram. Speed and accuracy are the two advantage of the mechanical press brake. The pneumatic press brakes uses the pressure of the air in developing tonnage on the arm while as the servo-electric brakes uses a servo-motor in driving a belt drive so as to exert tonnage on the arm.
Press brakes work by simply stamping cold steel into a mold referred to as a die. The machine is fed with the sheet and aligned over a mold that is special. The press brake press or lowers a boom so as to force the metal into the mold. By doing this, a cold formed metal object is formed. Any number of electronic machines is used by this brake for the alignment of the metal sheet. There are some that incorporate the use of CNC type arms which help in positioning the metal over a die. Mostly, a computer is used to time hydraulics and compress through a motor that is uses electricity. Read more in detail for Every Press Brake Operator to Ensure Safety during the Work.

All in all, safety should always be given a first priority in all press brakes operation.
These days CNC press brakes are widely used in comparison to the other types of press brakes since they provide lots of advantages as given below.
Easy Operation
The CNC press brake is very easy to operate and is a less labor intensive machine. The operator can therefore handle many machines at a time. These machines can be simply operated via touch, feel, and sound of the operator. Besides this, they are very user friendly and have a highly powerful controlling system.
Modern Design
The CNC press brake incorporates a modern design which enables the operator to easily arrange the sequence of bends. It also assists the operator to quickly manufacture the required product. Moreover the operator no longer has to estimate the required amount of pressure in order to create a specific degree of bend. Even the other factors such as length of flange, kind of material, amount of thickness, and degree of bend can be directly entered into the CNC control unit. The part to be manufactured can also be viewed in either the 2D or 3D finished version. Besides this, after the first part is programmed on the machine or through an offline PC, a less skilled operator can also easily produce the subsequent parts.
Simple Functions
A CNC press brake is a computer numerically controlled machine where all the required parts can be easily programmed and swiftly manufactured by semi skilled operators. This is possible as the control guides the operator through a stage-wise procedure. Actually the simple functions and programming steps of the machine can be learned and practically implemented in the workshop.
Flexible Programming
The flexible programming of the CNC press brake enables the operator to control the machine in simple English or any other suitable language. The various types of operations that can be performed are also available as options on the menu. Once the required operation is chosen, another list of questions appears on the screen regarding the cycle times, materials, pressures, and other elements related to the production process. And after the operator inputs the replies into the machine, the values are displayed on the screen for confirmation before starting the related task.

Multi Tasking 
The CNC press brake is a multi tasking machine which permits one operator to check the first part and also work on the program related to the second part; while the another operator can simultaneously work on programming the other parts.
Cost Saving
The CNC press brake is basically a highly appealing and very sophisticated machine. Moreover it includes top grade components, minimizes wastage and has higher repeatability and traceability. This equipment also helps to save costs in terms of machine setup around 45 percent; material handling around 35 percent; inspection around 35 percent; work in process around 25 percent; and parts cycle time around 50 percent.
Conclusion
Hence many users are now prefer using the CNC press brakes as they are highly beneficial as compared to the other types of press brakes available in the market.
In a nutshell, the CNC press brake has gained more advantages than the other conventional braking systems. Besides being able to produce more bends than other press brakes they are also user-friendly and easier to install. Their ease of operation offered by press brake manufacturers make them run much smoother with fewer breakdown. The current technology helps as there is a thickness detection software that analyses thickness throughout the piece to ensure that the bend is accurate and uniform. The brake press suppliers also promote them as there is less training needed to be imparted to machinists and much of time consumption is saved while offering supreme specialization.
A Press brake is an indispensable machine tool used for sheet bending and cutting metals in different shapes. With the help of a die the sheet can be molded and shaped into various forms. These machines are available in various sizes to bend sheets of different sizes. They are found in almost all industrial units.
Metals like brass, steel, aluminium, copper, tin etc. can be bent and shaped with press brakes. These are used for making objects like metal enclosures, frames, plates, cabinets etc.
Many different types of press brakes are available like;
Manual Press Brakes – Before the invention of more advanced press brakes, manual press brakes were the only machines for bending metal sheets. Force is applied with a screw for bending the metal sheet.
Mechanical Press Brakes – An electric motor and a flywheel are used to apply force. Dies and machinery used by these machines are more costly. The electric motor powers the flywheel which in turn powers the crank mechanism. This moves the ram to bend the metal sheet.
Hydraulic Press Brakes– These work with the pressure exerted by the hydraulic liquid or oil. They are extra flexible, have high capacity, are more durable and efficient. These are very easy to use and maintenance cost is low.
Hydraulic press brakes do not vibrate and the products made are of high quality. These machines consume less power and the risk factor is low. Compared to mechanical press brakes these are more efficient. You can easily adjust the speed according to the requirement.
