Press Brakes

Press brakes are manufacturing tools that are used to bend sand process sheet metal. The material is placed on a V-shaped die and pressed in from above with a punch. Die-press punch These machines can bend simple and complex parts and are used in a variety of industries, from automotive and aircraft to enclosures and cabinets. Whenever there is a need to bend metal panels, a press brake is essential, which makes them very popular in workshops and mechanical workshops.

Simply put, a press brake is a piece of equipment used to bend various forms of sheets, in many cases also steel. Most press brakes are long, narrow pieces of equipment that allow you to insert even larger pieces of sheet metal into them. Generally speaking, the press brake works by lowering the punch against the stock at the top of the die.

Press Brake Structure 

Press brakes come with four main components: mechanical parts, electrical parts, hydraulic parts and NC / CNC controller. These parts are located in the frame that is to support them and the fuel tanks when needed. The press brakes include an upper punch or punch that is lowered onto the lower die that holds the sheet in question. A lot of force is required for bending, and the press brake will use the relative motion of the working table (powered by a hydraulic gearbox) as well as the punch and die shapes to generate this force and obtain the desired component.

There are several different types of press brakes, the simplest and most widely used format is the manual press brake, also known as the press brake. As the name implies, these types require manual adjustment of bend dimensions, angles, and other factors in the process, with components such as clamping plates and various supports in addition to the workbench frame. A base and a pressure plate will also be present to allow for the proper bending to take place.

Press Brakes - Important Considerations

Material Type and Thickness

Make sure you have defined the correct material type in the machine controller of your press brake. This means a lot to the controller as it calculates tensile strength, yield strength, elasticity and a host of other factors based on the type of material. For example, if you bend A36 but program your controller using "mild steel", you will likely get poor results and need to compensate accordingly. The correct type of material you form is critical to a successful edge bending application. As important as the type of material, material thickness is just as important to forming success with your press brake.

Plates are known by gauge thickness, and gauges can vary by up to 5% in thickness from suppliers and still be acceptable and within range. However, 5% of a bend of about 1/2 ° above 10 'can have a huge impact on press brake bending success. Having said that, 5% of a bend of about 1/2 ° above 10 'can have a huge impact on press brake bending success. Measure the material and enter a decimal of the actual material thickness to ensure you get the right results on the press brake the first time.


Many of the press brake bending problems can be directly related to inaccuracies in the tooling. We often find that customer complaints about bending issues are directly related to worn, broken, or simply inaccurate press brake tooling. If you want the best results from a press brake, bet on the most accurate tooling you can buy. Premium tooling is more expensive, but lasts much longer, is extremely repeatable when removed / replaced for a press brake, and is very flexible as it is segmented, allowing you to create any side flange. You will invest 1 time in high quality press brake tooling that will last 3-5 times longer than cheap stuff while providing years of reliable bending.

Hydraulic vs. CNC

The main differences between hydraulic and manual press brakes are in force and timing. For starters, hydraulic press brakes that use mechanical force through hydraulics are typically used in applications where greater amounts of force are needed. Moreover, they provide the possibility of synchronizing the twisting and creating perfectly standardized elements. There are up and down press brakes each with different end products. A CNC press brake refers to something like a combination, an electro-hydraulic press brake with a servo. This piece, which comes with a hydraulic servo, but also a CNC controller and electric control system, is the most accurate available - it includes a spool and a rear stop for the specified accuracy.
