A lot of people keep asking questions like this.
I just collect that official definition here for you to under what is press brake. I also put my own understanding here.
The press brake is a machine for sheet metal fabrication, to realize the sheet metal bending function by bending mold.
A press brake is a machine tool for bending sheet and plate material,most commonly sheet metal. It forms predetermined bends by clamping the work piece between a matching punch and die.”

Besides, for the bending in the metalworking industry :
Bending is a manufacturing process that produces a V-shape, U-shape, or channel shape along a straight axis in ductile materials,most commonly sheet metal. Commonly used equipment include box and pan brakes, brake presses,and other specialized machine presses. Typical products that are made like this are boxes such as electrical enclosures and rectangular duct work.
Here we will discuss everything about press brakes or brake presses.
Press brake is divided into below several types:
It is the most common one among press brakes.
Manual press brakes are required to manually adjust the bending dimensions and angles when used. Manual press brake also contains worktable,supporters,and the clamping plate. The worktable is also mounted on the supporters, which consists of a base and a pressure plate.
Manual press brakes are much more complex in operation than other types of press brakes,therefore, to make mass production after confirming bending size and bending angles. When finished one batch of mass production,adjusting bending size and bending angles for continued production.
Classified by synchronization, the hydraulic press brake can be divided into torsion synchronization press brake, hybrid press brake , and electric hydraulic synchronization press brake.
Classified by movement, the hydraulic press brake can be divided into:Up moving press brake, down moving press brake.
Hydraulic press brake contains supporters, worktable and clamping plate. The worktable is placed on the supporters, consist of base and pressure plate. The base is connected with the clamping plate by means of a hinge and it is composed of shell, coil and cover plate. The coil is placed in the recess of the shell while the top of the recess is covered with a cover.
CNC press brake is one kind of press brakes to realize bending function by controlling slider stroke and back gauge.
When using CNC press brake, you only need to input the pieces number of the work piece which required for bending as well as bending angle for each step, the CNC press brake will finish bending according to the steps you just set in the controller.
Advanced CNC press brake mainly adopts hydro-electric servo system and grating ruler to form closed-loop control. It features high control accuracy, as well as bending accuracy and repositioning accuracy.
The operation of CNC press brake can be flexible, both over length plates bending with tandem press brake and short work piece fabrication with normal press brake can be realized, which not only improve press brake utilization ratio but reduce energy consumption.
When someone wants to purchase press brake, sometimes he will be confused with CNC press brake and NC press brake.
